摘要
运用Simpack建立了高速列车动力学模型,分析了高寒地区列车制动过程中的受力情况,设计了400 km/h高速列车紧急制动与最大常用制动减速度曲线,并进行了黏着校核。结果显示所设计的减速度曲线能满足400 km/h高速列车的制动需求。运用MATLAB/Simulink建立制动系统模型,通过仿真计算得到高寒地区干燥和冰雪条件下紧急制动距离和最大常用制动距离。
The dynamic model of high-speed train was established by Simpack.The force of the train braking process in the alpine region was analyzed.The emergency braking and the maximum common deceleration curve of the 400 km/h high-speed train were designed and the adhesion checking was carried out.The results show that the designed deceleration curve can meet braking requirements of the 400 km/h high-speed train.The model of braking system was established by MATLAB/Simulink.Through the simulation and calculation,the emergency braking distance and the maximum common braking distance were obtained under the dry and snow conditions in alpine region.
