Research and Simulation of ABS Control Method
Authors: Zhang Wei , Xu Guan Neng , Guo Xue Xun , Zhang Wen
Published: February 2015

Based on the ABS model of a single wheel system, the traditional logic threshold, PID and fuzzy control method have been used to study the control system of commercial vehicle’s ABS. As the most important task of commercial vehicle’s ABS is to prevent the two front (steering) wheels from locking, the slip ratio should be controlled strictly in the safe range. A very short time of locking may cause the failure of steering, so control method which can keep slip ratio in the secure scope accurately can help vehicle avoid the danger of runaway. Set up the model on Simulink platform. Then, use the three control methods to control the ABS. By comparing and analyzing the processes and results under the control methods, find an appropriate way that can provide the most secure and effective control. From the perspective of processes (slip ratio changes), the simulations under the three control methods show the PID control gives the best slip ratio curve. The curve is almost coinciding with the ideal slip ratio curve. The oscillation of slip ratio given by fuzzy control is the most sever. From the point of view of the results (braking distance), the braking system with PID control has the shortest braking distance while with the fuzzy control has the longest. That is not to say fuzzy control is not advanced but the actual experiences difficult to get. And with the long response time, the fuzzy control is not suitable for commercial vehicle’s ABS. As a result and with the development and decreasing cost of PID controller, it is competitive in today’s ABS market.

Published: February 2015

Sorption selectivity of a number of REE ions (Pr3+, Nd3+, Sm3+, Yb3+) was studied with the help of the KB-2E macroreticular carboxylic cation exchanger with a different content of a crosslinking agent. Selectivity was weakly dependent on the degree of crosslinking of the cation exchanger and concentration of the sorbed metal ion, which could be explained by the macroreticular structure of the cation exchanger. An increase in sorption selectivity of heavier REEs (Yb3+) correlated with a decrease in their crystallographic radius. It was concluded that a coordinate link of REE ions and oxygen donor atoms - a part of the cation exchanger - had been formed.

Novokuibyshevsk refinery vacuum gasoil (VG) with a high sulfur content (2.02 % wt.) thermocracking results are represented in abstract. Its density is 909.8 kg/m3. Material balance and fractional composition of liquid products cracking and reduction of sulfur containing in every component of it was established. Based on experimentally measured parameters we calculated gas, liquid, coke yields depending on process conditions. The amount of hydrocarbons and resins-asphaltens components increased in the vacuum gasoil cracking products, but these products have lower molecular weight in comparison to initial object. Cracking liquid products composition, which were gained after vacuum gasoil benzoyl peroxide (BP) oxidation pretreatment, specific differences from VG thermolysis products with BP used as radical forming addition were established.

This paper introduces a new technique to test fatigue cracks in concrete that occur during its maintenance. The principle of the technique consists of exposing the object to pulsed mechanical excitation. As a result, acoustic waves start to propagate in the sample. Under the action of acoustic waves the dipole moments of double electric layers on the boundaries of components in concrete are changed and piezoquartz which is a part of sand and gravel is polarized. The external electric field occurs and is registered by a signal receiver placed near the object under study. The possibility of using this technique for crack nondestructive control is studied in the paper. The technique capabilities are shown by comparing the parameters of electric response on pulsed mechanical excitation when testing the defectless concrete and the same sample after developing the artificial crack in the concrete.

Cuprum-zinc catalysts with chrome and zirconium additives were obtained by continuous codeposition within this study. XRD showed the presence of cuprum, zinc, chrome, and zirconium oxides phases. Catalytic activity was studied under the mixed loading with HZSM-5 zeolite as a catalyst for methanol dehydration during the STD-process reaction. TPR method was used to show that the reduction of catalysts takes place up to 350 °С. The maximum СО conversion value for sample CuZnAl amounts to 60 %, for sample CuZnAlСr - 83 %, and for sample CuZnAlZr it is 68 %. DME yield amounted to 18 % at a temperature of 240 °С for sample CuZnAl, for CuZnAlZr – 15 % (Т=240 °С), and for CuZnAl – 11 % at 220 °С.

Humic substances are the major components of soil, peat and brown coal. They can be fractionating into fulvic acids (FA), brown humic acids (BHA) and gray humic acids (GHA). In this work we investigated the influence of mechanochemical modifications on structural composition of HAs main fractions using the methods of IR and 1H MRS spectroscopy. The IR spectroscopy results has shown that HA has different chemical composition in comparison with GHA and BHA. Potentiometric titration showed that mechanoactivation (MA) with thiourea increases the amount of oxygen-containing groups up to 2.5. For the first time we studied the impact of modifying agent of thiourea on the structural composition and acid-base properties of HAs major fractions - GHA and BHA during the mechanoactivation process.

The results of investigation of the structure, physical and mechanical properties of the Ti-Nb alloy ingots with different composition obtained by arc melting are presented. X-ray diffraction and microstructural analyses were used. Microhardness was measured and the Young’s modulus of the alloys was evaluated. When the content of niobium in the alloy changes from 10 to 40 mass.%, phase composition of the alloy varies from α-and α'-phase (10 mass.% of Nb) to α'-, α''- and β-phases (25 mass.% of Nb), to the β-phase (40 mass.% of Nb). The alloy containing 40 mass.% Nb has the lowest Young’s modulus.

The paper assessed the possibility of using acoustic emission from the dielectric sample during stepwise loading. The electromagnetic signal from the sample was detected by using an apparatus of mechanical repeatedly pulsed excitation of the sample at each stage of loading. It was found that the response consists of a deterministic component (due to the excitation pulse) and random components noise and acoustic emission. It were allocated random components, calculated their standard deviations. The influence of the electromagnetic emission on standard deviation of the random component of response under step load on the specimen was evaluated. It has been shown that the component of the electromagnetic emission can be an informative parameter to evaluate defectiveness of the object of a dielectric material under load.

Preliminary evaluation of toxic effect of commercially manufactured carbon nanostructured material based on multi-walled carbon nanotubes (MWCNT) upon laboratory mice C57B6/DBA2 males was carried out. It was found that thirty-day oral administration of nanotubes in doses of 0.3 and 3 mg/kg has no effect on liver condition, while administration of 30 mg/kg leads to formation of inflammatory infiltrates together with hepatocyte structure modification. The obtained results are of potential interest for development of industrial safety standards in nanomaterial handling and for development of standards for reproductive toxicity of carbon nanomaterials.
