## 基于MATLAB的轨道车辆动力学仿真后处理程序设计

Dynamics Simulation and Post-process Programming of Railway Vehicle Based on the MATLAB
Abstract: In the context of rapid development of technology, China has opened the "High-speed railway era" with numerous senior engineers’ efforts. From scratch, from the controversial to its promote, in 10 years, Chinese high-speed rail trains come with unimaginable speed , which changed China and shocked the world. Reflected in the speed of development of high-speed railway, its roots "power" is the most important problem in this subject, speed increasing brought out a series of rail vehicle dynamics performance issues. To address these challenges, engineers will generally do some dynamics simulation tests on well-designed rail vehicle, the corresponding track and related parameters .
This article used the MATLAB matrix laboratory to design program for general SIMPACK data reading into the data file, output calculation of dynamics index, after combine with the corresponding MATLAB / GUI interface ,we can do complete analysis and calculation on round of speed across, yaw angle, lateral wheel rail forces, derail factor, frictional work, Sperling index. 源自六[维^论'文]网.加7位QQ3249'114 www.lwfree.cn
