Authors: Tan Zhaozhao , Li Chengliang , Shu Guogang , Liu Wei , Li Qiulin
Published: July 2018

The effect of pre-deformation on the precipitation process of Cu-rich clusters in reactor pressure vessels (RPV) model steel is studied. In this research, Fe-1.16wt%Cu binary alloy is selected as RPV model steel to simulate the precipitation process of Cu-rich clusters. The solid-solution Fe-Cu alloys were cold rolled with pre-deformation of 0, 10%, 25%, 40%, 60%, followed by aging at 450°C for a series time. The dislocation density, Vickers hardness and microstructure evolution of Fe-Cu alloys after aging were determined. It is revealed that the Vickers hardness of un-deformed specimens reaches to peak hardness after aging at 450°C for 100 h, while the specimens with larger dislocation density reach to peak hardness faster from the Vickers hardness test result. The result of transmission electron microscopy (TEM) indicates that pre-deformation promotes the process of precipitation of Cu-rich clusters and inhibits the growth of the Cu-rich clusters.

Authors: Zhou Feng , Gan Jianjun , Du Xin , Cui Ligang
Published: July 2018

The damping property of viscoelastic dampers is mainly based on the shear hysteretic behaviorof viscoelastic materials, so as to reduce the dynamic response of viscoelastic materials. Therefore, theviscoelastic damping properties of viscoelastic materials greatly affect the viscoelastic dampers. At present, viscoelastic materials mainly use rubber materials, but in this thesis, the excellent properties of polyurethaneelastomer materials are used to replace rubber materials and applied to viscoelastic dampers. However, purepolyurethane elastomer damping properties are related to poor performance, so it should be modified. Basedon the research of inorganic filler-modified polyurethane elastomer, the research group modified the threekinds of organic chemicals with hydroxyl silicone oil, HTPB liquid rubber and epoxy resin E-51, in the lowfrequency region of 0.025Hz-1.5Hz through the dynamic load test machine to test the dampingperformance.

Authors: Wang Yan-chao , Wang Xiao-ming , Mei Yu-lin , Chang Nai-wen
Published: July 2018

Pentamode (PM) metamaterial is a kind of acoustic metamaterial generally designed from a general material and made by a periodic array of micro-truss structures. The paper presents an optimization method for the design of PM metamaterial structure, and this kind of structure has usually special physical properties to guide the acoustic wave to propagate according to the design path. In order to construct the optimization model, the micro-truss unit cell is firstly investigated deeply, and the relationship between the effective elastic modulus of PM materials and the structural parameters of micro-truss unit cells is established. With incorporating the transformation acoustics algorithm into the optimization process to predict the theoretic material parameters of the current design structure, the constraint of the material property in the design structure is converted into the rod size constraint of micro-truss. As a result, the design of PM material structures can be realized as a problem of structure size optimization, and the optimized result can meet the requirement of PM metamaterial property and the theory of transformation acoustics. And also, the total stability of the PM material structure is also ensured by the balance rod forces constraints in the optimization process. Finally, a numerical example of PM material structure is presented.
The effect of V2O5-WO3-TiO2 electrode thickness on ammonia sensing properties for potentiometric sensor
Authors: Wang Chao , Yang Bin , Xu Jinlong , Xia Feng , Xiao Jianzhong
Published: July 2018

SCR catalyst V2O5-WO3-TiO2 was synthesized for fabricating sensing electrodes of potentiometric ammonia sensor in this work. As an important sensing electrode structural parameter, the influence of the electrode thickness on sensor properties was investigated. The VWT electrodes with the thickness of 9.8, 15.2 and 24.5μm were made by different screen printing frequency. As the thickness increased, the NH3 sensitivity of the sensor decreased from 71.9 to 17.0 mV/decade, and the response/recovery rates also slowed down rapidly. Considering the EIS results, it is believed that with the increase of electrode thickness, more NH3 molecules are consumed by catalytic reactions in VWT electrode, which reduces the concentration of NH3 involved in the electrode reaction at the three phase boundary. The weakened reaction reduces the NH3 sensitivity and increases the interface resistance of the TPB. The increased VWT thickness retards the diffusion of NH3 molecules, and finally prolongs the response/recovery times.

Authors: Zhao a Maoyu , Meng Zhengzheng , Tian Chunyan , Li Ping
Published: July 2018

The relation between residual stress and tensile strain is an important factor for evaluating plastic formation grade of steel sheet. The degree of plastic deformation (Δl) and elastic recovery (δ) were obtained by measuring the length of DP600 steel sheet sample under different tensile test conditions, i.e. five tensile strains (ε). Furthermore, the average residual stress value in the surface middle (the diameter of 10 mm) region of above tensile samples was analyzed by x-ray diffraction (XRD) in the crystal plane of (211). By processing the diffraction peak angle (2θ) with half width high method (FWHM), the relationship between sin2(ψ) and diffraction angle is attained by least squares method. On this basis, a mathematical model was established to correlate the tensile strain with the residual stress in the present study. The results show that the residual stress decreases and the elastic recovery increases with the increase of tensile strain (ε≤0.205). The relation between residual stress and tensile strain can be described with an exponential function . Finally, a function of tensile strain, elastic recovery and surface residual stress is established, by which a reasonable forming condition, viz. ε=0.205, δ=2.65 mm is determined for achieving the smallest σψ.

Authors: Ren Zhong , Huang Xingyuan , Xiong Zhihua
Published: July 2018

The effect of compression angle of die on the extrusion forming of plastic pipe was numerically studied by using the finite element method. Based on the geometric models of plastic pipes with four different compression angles, the extrudate swell results of plastic pipe under the different compression angles are numerically simulated. Numerical results show the extrudate swell phenomenon for the little compression angles are larger than that of the large compression angles. To eliminate the extrudate swell effect and keep the wear-resistant strength of the plastic pipe, the gas-assisted extrusion method was used in this paper. The numerical results fully show that the shear stress of melt was greatly eliminated and the high pressure was still maintained by using the gas-assisted method.

Published: July 2018

In order to improve the working efficiency of hot blast stoves, reduce environmental pollution, reduce labor intensity and improve combustion efficiency, this paper uses ANSYS software to simulate the temperature field and flow field of the hot blast stove, and uses the PID controller to realize the automatic control of the hot blast stove. The model and working principle of the hot blast stove are briefly introduced. The operating parameters (blowing fan air flow, coal intake) of the hot blast stove are briefly studied. The results show that the amount of air flow of the blast furnace depends on the coal intake of the hot blast stove, which is generally per kilogram of coal. 8m3-10m3- air is required. When the coal intake is 120kg/h and the air volume of the blower is 1200m3/h, the hot blast stove can work stably with high efficiency. The results obtained are input into the database for later combustion. The work provides a theoretical basis.

Authors: Lang Yuxiao , Jia Lianguang
Published: July 2018

In order to study the seismic performance of wedge-shaped light steel castellated portal frame, the finite element analysis software Abaqus is used to simulate the seismic behavior of the portal frame with a single span hexagonal hole with a span of 24m. The influence of the opening ratio and the distance between the first hole of the near column and the end to the column edge on the hysteretic curve, skeleton curve, stiffness degeneration, ductility and energy dissipation capability are analyzed and the ultimate destructive form is also obtained. The results show that under the low cycle reciprocating load, the castellated light steel portal frame forms the plastic hinge on both sides of the structure near the first hole, and the structure loses its carrying capacity. The greater the opening ratio is, the lower the ultimate bearing capacity is, and the stiffness degeneration is more notable, ductility and energy dissipation are worse. The distance between the first hole of the near column and the end to the column edge has great influence on the ultimate bearing capacity, stiffness degradation and ductility. The greater the distance is, the better the ultimate bearing capacity and the ductility are.
Research on Stresses of Narrow Joints Caused by Construction Process of CRTSIISlab Track
Authors: Zhu Yongjian
Published: July 2018

A separate finite element model of 1/4 unit track slab of CRTS IIslab track was established for the analysis of the influence of construction process on stresses of narrow joints. When track slabs were connected by tension and when wide joints hardened, the impacts of the longitudinal connection of CRTS IIslab on stresses of narrow joints were analysed. The results show that when track slabs are connected by tension, the bonding states between track slab and mortar layer have little effect on track slab expansion displacement and the re-compression of narrow joints caused by the tensioning force cannot be ensured. If track slabs are connected by tensioning force after the concrete hardening of narrow joints, compressive stresses of narrow joints can be increased by 3.03 MPa. Due to the influence of longitudinal connection of CRTSIIslab, the respective track slab temperature for wide joints hardening Tk and narrow joints hardening Tz are difficult to keep consistent. When wide joints hardened, it potentially makes the compressive stresses of narrow joints zero or very large. In order to keep the narrow joints compressed when wide joints hardened, the measures to control Tz and Tk should be taken to make Tk slightly higher than Tz.

Published: July 2018

The contact performance of various mechanical parts has important influence on the static, dynamic and motion response of mechanical equipment. The characterization of rough surface topography is the basis for the study of friction, wear and contact deformation between mechanical bonding surfaces. By analyzing the various models of the characteristic parameters of mechanical interface, we provide a systematic research idea for the model of mechanical joint surface in the future. For further details on rough surface profile, the G-W model is put forward. Then the M-B model perfects its lack of scale independence. The relationship between actual contact area and load is derived from the M-B model based on fractal geometry theory. These formulas are used to study the characteristic parameters of mechanical interface, and the fractal model of contact damping and loss factor is established. Since fractal parameters are not limited by sampling length and resolution of measuring instrument, the new models are more reasonable than before. However, just as the M-B model needs to be improved, the model based on this need to be further studied, and the application of the model also needs to be explored more.

Published: July 2018

To effectively enhance the service life, the research of milling machine scraper structure design and welding process are optimized. Through the structural optimization analysis, the improved structure is obtained, and the working resistance force is reduced. The full factor test is used to optimize the brazing process, and the best parameters are obtained, which improves the shear strength. The accuracy of the model is verified by experiments. The results show that compared with the working resistance force, the improved scraper tends to be slow and the peak value is smaller. The cutting rake and relief angle of the scraper are optimized. When the cutting rake angle is 6° and the cutting relief angle is 9°, both working resistance force and impact force are minimum. It proves the accuracy of the simulation results. Using CT861 solder, brazing temperature is 75°C, and the brazing time is 10s. While the cooling method uses furnace cold, the minimum value of shear strength is 200MPa. The average working life of the scraper is raised from 800 hours to 1600 hours after the optimization design. Research results have guiding significance for the structure design and the welding process optimization of the scraper.

In order to improve the efficiency of community mining algorithm and the accuracy of community classification, a community mining algorithm based on structural similarity is proposed in this paper. The algorithm uses the structural similarity as an edge weight to perform the operation of the loop deletion, and implements community merging for isolated nodes, thus improving the precision of community division. The algorithm is compared with GN and SSNCA algorithm in classic data sets such as Zachary network, football data and dolphin social network. The experimental results show that the algorithm can effectively detect the community structure in complex networks, and the accuracy of classification and operation speed are obviously improved.

Ziel der Studie Die Studie analysiert Schmerzverhalten und Ergebniskonsistenz im Rahmen der arbeitsbezogenen Leistungsdiagnostik mit dem FCE-Assessmentsystem Sapphire®.

Methodik Insgesamt wurden 129 stationäre orthopädische Rehabilitanden untersucht. Die Probanden wurden nach den Sapphire-Testergebnissen in 4 Gruppen unterteilt: (1) auffälliges Schmerzverhalten ohne Inkonsistenz, (2) Inkonsistenz ohne Selbstlimitierung durch Schmerz, (3) Schmerzverhalten mit Testinkonsistenz (komplexe Auffälligkeiten) und (4) keine Auffälligkeiten von Schmerzverhalten und Testkonsistenz (Referenzgruppe). Mittels multinomialer logistischer Regressionsanalysen wurden die Faktoren bestimmt, die mit dem Auftreten der Auffälligkeiten zusammenhängen.

Ergebnisse Das Rentenbegehren erwies sich als Kernprädiktor von negativer Befundverzerrung mit auffälligem Schmerzverhalten. Es ergab sich kein Zusammenhang mit dem Rentenwunsch bei alleiniger Auffälligkeit des Schmerzverhaltens.

Schlussfolgerung Konsistenz- und Schmerzverhaltensanalyse erwiesen sich als nützliche Instrumente, um negative Befundverzerrungen und mögliche Schmerzbewältigungsstörungen zu identifizieren. Weitere Forschung zur Klärung der Schmerzbewältigungs- und Motivationsproblematik bei Personen mit auffälligen Testergebnissen erscheint vielversprechend.

Published: July 2018

Lepra ist eine chronische bakterielle Infektionskrankheit durch Mycobacterium leprae, derzeit leiden weltweit circa 3 Mio. Personen daran. Lepra ist nicht hoch kontagiös, für die Übertragung steht die Tröpfcheninfektion im Vordergrund. Die vielfältigen klinischen Symptome sind durch den Immunstatus des Betroffenen, die aktuelle Bakterienladung sowie Bestandsdauer der Krankheit vor der Diagnosestellung bestimmt. Zwecks Behandlungsstrategie wird die Krankheit in bakterienarme (tuberkuloid, borderline-tuberkuloid) und bakterienreiche (borderline-borderline, borderline-lepromatöse und lepromatöse) Formen unterteilt. Erregernachweis erfolgt durch mikroskopisches Direktpräparat, Histopathologie beziehungsweise mittels PCR. Die Kombinationstherapie mit Dapson, Rifampicin und Clofazimin gilt als Standard (WHO).
