Introduction of the speaker:Di Wu, doctoral candidate from College of Transportation Engineering, will give a lecture titled “The calculation model of saturated porous media and suspended particles’ deformation, transfusion and coupling diffusion”. Wu will mainly introduce the modeling method of displacement field, seepage field and diffusion field in the Suspension-Filtration system and discuss the solving algorithm for the model which is aims at describing the universal phenomenon of Engineering and Nature by the mathematical language.
Chao He, doctoral candidate from College of Transportation Engineering, will give a lecture titled “Application of coupling infinite BE&FE method in the analysis of vibration response of subway tunnel vehicle”, he will analyze the application situation and idea of the method of coupling infinite BE&FE which is aims at solving the problem of system response from subway tunnel vehicle in the soft soil area.
Yuan-Jin Ji, doctoral candidate from Institute of Rail Transit, will give a lecture titled “Research on the mechanism and influence factors of guide rail wearing of Tramcar”, he has investigated the rail wear situation of Zhangjiang tramcars and inferred two contact status of guide wheel and guide rail. On the basis of it, Dr. Ji will put forward the equivalent mechanical model which described the contact relationship of guide wheel and guide rail, he will also calculate the contact situation of wheel-rail of Translohr tramcar in different radius curve by a simulate method and measured the guidance force of Zhangjiang tramcars in practice. By the comparing of simulation data and measured data, Dr Ji will analyze the influence of guide wheel pressure and length of guide peg to the guide rail wearing.
Dr. Yi-Hong Yuan, doctoral candidate from Institute of Rail Transit, will give a lecture titled “Detection technology of maglev rail line type”, he will mainly introduce the theories of high speed maglev transportation system and the principle of the error detection including the related equipment. In the principle part, Dr. Yuan will explain the inertia reference method and its application in the track geometry car and detection equipment for the maglev guide way. By using the inertia reference method, the non-contact measurement of maglev guide way in high speed situation can be realized.
Looking forward to your participation!
