Simulation On Anti-skid Braking System Of Emu Based On Amesim

On April18,2007, the Harmony EMU was officially put into use in China,which indicates that our country has entered into the ranks of high-speed railway countries. Since then, China’s high-speed railway business has developed very quickly.With the continuous improvement of the speed, the train put forward higher requirements on anti-skid braking system. Developing a new generation of anti-skid braking system, has become an urgent task, while simulation and analysisis on the train anti-skid braking system is an effective way to assess the performance.Anti-skid braking system is very important to traffic safety of high-speed train. It does real-time detection of the speed of each axis when the train is in the process of brake, and it then judgment that the train whether occur slide or not with the speed difference between shafe speed and reference speed and other basis. When it considers that slide is occured, the corresponding brake cylinder will take stage exhaust. When adhesion restores, the brake cylinder will puff again. In addition to achieve the anti-skid purpose, the train anti-skid braking system can also take full advantage of adhesion, shorten the braking distance and increase traffic safety.This paper gives brief discription to the development of the train braking system; intrduced brake control methods; described the composition of the anti-skid braking system;given a more detailed description of CRH2type EMU’s anti-skid braking system; described the use of the simulation software whice named AMESim; described the method of using AMESet’s custom modeling in detail; with CRH2as the object, using AMESet, the various parts of the anti-skid braking system were custom modeling; with custom modeling components, the anti-skid braking system model was built and simulated. The simulation results show that we can do good simulation and analysis of anti-skid braking system by using AMESim, and because of the characteristics of the software itself, the process of simulation is concise and efficient.
