Article ID: 1003-6326(2005)03-0686-05 Mass transfer mathematical model for one-side plate steady-state ultrafiltration QIU Yun-ren(邱运仁)1, ZHANG Qi-xiu(张启修)2 (1. School of Chemistry...: A mass transfer mathematical model was developed based on one-side plate steady-state ultrafiltration(UF), and the numerical solution was obtained by Crank-Nicolson finite difference method......
J. Cent. South Univ. (2012) 19: 163-167 DOI: 10.1007/s11771-012-0986-5 Pendulation reduction on ship-mounted container crane via T-S fuzzy model JANG Jae Hoon, KWON Sung-Ha, JEUNG Eun Tae Department... of ship-mounted crane is derived and a control method using T-S fuzzy model is proposed. Simulation results are given to illustrate the validity of the proposed design method and pendulation of ship......
Constitutive model for casting magnesium alloy involving spherical void evolution CHEN Bin(陈 斌), PENG Xiang-he(彭向和), FAN Jing-hong(范镜泓), SUN Shi-tao(孙士涛) Department of Engineering Mechanics... of the voids was presented. By introducing the presented void-evolution equation to a nonclassical elastoplastic constitutive equation, a constitutive model involving the void evolution was put forward......
J. Cent. South Univ. Technol. (2011) 18: 285-289 DOI: 10.1007/s11771-011-0692-8 Prediction model of residual stress field in aluminum alloy plate GONG Hai(龚海), WU Yun-xin(吴运新), LIAO Kai(廖凯... was obtained. Based on the measured surface stress, stress value of key points and stress distribution shape, the internal stress distribution can be reconstructed. The experiments show that the model......
Selection model of trip time for rural populationFENG Zhong-xiang(冯忠祥)1, YUAN Hua-zhi(袁华智)2, LIU Jing(刘静)3, GAO Xuan(高璇)4, ZHANG Wei-hua(张卫华)1(1. School of Transportation Engineering, Hefei... of trip time choice were analyzed. Based on the basic theory of disaggregate model and its modelling method, nine grades were selected as the alternatives of trip time, the variables affecting time choice......
Coupled hydro-mechanical analysis of slope under rainfall using modified elasto-plastic model for unsaturated soilsWANG Liu-jiang(王柳江)1, LIU Si-hong(刘斯宏)1, FU Zhong-zhi(傅中志)2, LI Zhuo(李卓)2(1. College... Barcelona model (BBM) are present. One is the replacement of the net stress by the average skeleton stress in unsaturated soil modeling, and the other is the adoption of an expression for the load-collapse......
Article ID: 1003-6326(2005)02-0344-05 Model of magnetostrictive actuator LI Lin(李 琳), ZHANG Yuan-yuan(张媛媛) (School of Jet Propulsion, Beijing University of Aeronautics and Astronautics, Beijing 100083, China) Abstract: The hysteresis of the magnetostrictive actuator was studied. A mathematical model of the hysteresis loop was obtained on the basis of experiment. This model depends......
