Authors: Selman Abbas M. , Hassan Zainuriah
Published: August 2014

Effects of annealing treatment on growth of rutile TiO2nanorods on structural, morphological and optical properties of TiO2nanorods were investigated. The nanorods were fabricated on p-type (111)-oriented silicon substrates and, all substrates were seeded with a TiO2seed layer synthesized by radio-frequency reactive magnetron sputtering system. Chemical bath deposition (CBD) was carried out to grow rutile TiO2nanorods on Si substrate at different annealing temperatures (350, 550, 750, and 950 °C). Raman spectroscopy, X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) analyses showed the tetragonal rutile structure of the synthesized TiO2nanorods. Optical properties were examined by photoluminescence spectroscopy. The spectra exhibit one strong UV emission peak which can be seen at around 390 nm for all of the samples. In the visible region, TiO2demonstrated two dominant PL emissions centered at around 519 and 705 nm. The experimental results showed that the TiO2nanorods annealed at 550 °C exhibited the optimal structural properties. Moreover, the CBD method enabled the formation of photosensitive, high-quality rutile TiO2nanorods with few defects for future optoelectronic nanodevice applications.

Authors: Zhang Lin Lin , Li Xiao Yang , Chen Rong , Zeng Yan Jun
Published: August 2014

The main objective of this study is to analyze the influence of joint interface on mechanical behavior of two cylinders by modeling different geometry with Finite Element Method (FEM). The structures are continuum model (CM), joint interface model with different materials (JIM1) and joint interface model with same materials (JIM2). The displacement-load relationship, equivalent plastic strain (EPS), deformation and contact pressure based on three models are gained. FEM results indicate that under the same load, the displacements of three models are various in loading and unloading processes. The EPSCM is relative stable originally and then decerase quickly while the EPSJIM1 and EPSJIM2 grow rapidly and fall slowly later.The deformation of CM, JIM1 and JIM2 under 300Mpa are 62.5μm, 33μm and 68.13μm respectively. The contact pressure of JIM1 is smaller than JIM2. The effects of frictional coefficients (vary from 0 to 1.0) on deformation and contact pressure are also investigated. Results show that joint interface make the structure’s behaviors different compared with continuum structure and this study can provide reference for the design of structures with joint interface in machinery.

Authors: Liu Fu Pei , Shang Jian Zhong , Luo Zi Rong , Zhang Tao , Yu Nai Hui
Published: August 2014

Unlike commercial sliding rails, space sliding rails need to meet complex mechanical requirements in the state of ground tooling, launch and on-orbit. The former could slide smoothly while their carrying capacity is low. As a result, they cannot be applied directly to the space stations, manned spacecrafts and other space probes. Hence, it is necessary to design a kind of full-pulling sliding rails which can be suitable for three completely different mechanical conditions. In this paper, we firstly built the mechanical models of the ground tooling, launch and on-orbit state, then a kind of sliding rails is designed according to the mechanical models, finally, a simulation analysis was carried out on the designed sliding rail. The result shows that this kind of sliding rails meets all the design requirements, which verifies the validity of the models.

Authors: Li Jia Bin , Zhu Gui Bing , Ou Zhi Shan
Published: August 2014

The length of the anchor chain released directly influence the holding power of anchor and holding power of anchor decides the safety of the ship in the state of anchoring. In order to calculate the length of the catenary for anchored vessel in static hydraulic condition, Parabola and catenary mathematical model has been used in this paper to the data processing. These two kinds of thoughts are both based on the infinitesimal dividing model. The parabola method is using the Taylor series expansion to calculate the results of former 3~5 terms respectively, while catenary one uses the differential solving method. Through the example analysis to compare the accuracy of results obtained by these two methods, the conclusion can be obtained that parabola method is closely related to Taylor expansion terms. For a certain range of the anchored catenary length, the more Taylor series expansion, the more accurate results we can get; the gap of the results calculated by these two methods can be neglected. The catenary method is more accurate than that of parabolic one when the length of the catenary beyond this range.

Published: August 2014

Now a day’s sustainable development becomes an increasingly significant goal in the evaluation and promotion of Industries. There is currently considerable interest in developing sustainable acoustic absorbers. This research aims to develop and characterize composite materials made of Epoxy resin reinforced with luffa fibres as sustainable acoustic absorbers. The fibres where chemically modified by alkaline treatment and its effects on the fibre-matrix interaction were also evaluated. The effect of chemical modification on fibre morphology was studied by Scanning electron microscope (SEM). Likewise, the sound absorption coefficient of composites were studied using 2 types of Impedance tube methods namely Two microphone transfer function and standing wave method. The thermal analyses of composites were made using Thermogravimetric analysis. The sound absorption coefficient of untreated and treated composites across a range of frequencies was very similar. To be more specific, untreated composites appeared to perform better than those of treated ones. After chemical modifications, the SEM characterization showed that the alkaline treatment changed the morphology of fibers, resulting in decrease in sound absorption coefficients of composites. This is probably due to the new morphological aspect. The thermal characterization of composites shows that dehydration and degradation of lignin occurred around 40 - 260°C and maximum percentage cellulose was found to decompose at 380°C.

This paper discusses MWDSP under hybrid uncertain environments where the weights of vertexes are random fuzzy variables. First, random fuzzy theory is introduced to describe these hybrid uncertain variables. Then we propose three decision models based on three different decision criteria to solve MWDSP under hybrid uncertain environments. To solve the proposed models, we present a hybrid intelligent algorithm where random fuzzy simulation and genetic algorithm are embedded. Numerical experiments are performed in the last to show the robustness and effectiveness of the presented hybrid intelligent algorithm.

The objective of this research is to study the mechanical properties of recycled wood particles epoxy matrix composites through the manipulation of composites wood particles size and weight fraction for tensile tests with different strain rate. Wood saw dust has been collected from a saw mill, dried and sieved into 300 and 600 μm. Unsieved wood particles were also used in this study. Each of the categories of wood particles was mixed into Epoxy resin with weight percentage of 20% and 40% of total composites to produce dumbbell-shaped tensile test specimens. Result shows that there is an optimum wood particles size where the tensile properties are at the highest before the properties start to decrease with increasing particles size, except for 20% wt. wood particles whereby the Young’s modulus is the highest with mix (largest) wood particles. With increasing wood particles weight percentage, tensile strength decreased while young’s modulus increased. A wood plastic composite (WEC) was shown to be strain rate sensitive whereby tensile properties increased with increasing strain rate. Our study proves that WPC can be very advantageous due to its higher average tensile strength and also high young’s modulus compared to commonly used materials in the industries.

Oil is an important energy and chemical raw materials and strategic materials. Nowadays, the layered water injection test technology become the key factor of oilfield production. According to different types of formation and for the artificial fracturing injection wells, this paper studied the infinite boundary, uniform flow and vertical cracks well, infinite diversion vertical fractures and conductivity vertical fracture wells’ absorbent law. The method to do all of the above work is to solve the equation of dimensionless bottomhole pressure in different formation and boundary conditions. The indicating curve of infinite uniform flow formation, unlimited conduction and limited conduction vertical fractures wells are almost identical, which means that the type of vertical fracture has little effect on the indicate curves of injection wells.

In order to find out the infiltration rule of expansive rock canal slope, take the expansive rock in south-to-north water diversion project as sample. First, soil-water characteristic curve of expansive rock test was carried out. It predicts the unsaturated infiltration coefficient. Then, based on the test result and the saturated-unsaturated seepage theory, the varying law of seepage field under different rainfall intensity was studied. The results show that when the rainfall intensity is less than the slope material saturated permeability coefficient, with the increase of slope rainfall duration, the underground water level rises gradually, but the increase is very small. Meanwhile, there isn't saturation zone on the surface of the slope. When the rainfall intensity is greater than or equal to the slope material saturated permeability coefficient, after one day's continuous rainfall, saturation zone appears in the slope surface. After 5 days' continuous rainfall, saturation zone appears in the middle of the slope (elevation: 89m). After 12 days' continuous rainfall, the underground water level arrives at the slope toe. So, in order to prevent slope sliding under the rainfall infiltration condition, both the slope toe and the middle of the slope should all be given enough attention, and it is not only necessary but also essential to take drainage measures in the relevant position in advance.
