铁道车辆运行稳定性虚拟试验系统研究

Research on Virtual Test System for running stability of railway vehicle

铁道车辆运行稳定性对保证铁路运营安全具有重要影响。采用基于Web的技术方案,对铁道车辆运行稳定性系统总体设计方案进行分析。利用MatLab分析计算车辆运行稳定性,在三维CAD软件和VRML语言支持下建立虚拟试验场景。通过Asp.Net和SAI,控制和操纵网络虚拟环境中车辆运动状态。系统运行实例表明,建立的虚拟实验系统能在网络环境下有效地分析与仿真铁道车辆运行稳定性。

The running stability of railway vehicles played an important role on train operation safety. On the Web-based technical scheme, the total architecture proposal for the Virtual Test System of running stability for railway vehicles was analyzed and explained. The running stability was calculated by MatLab, and virtual test scene was constructed by CAD and VRML. The motion state for railway vehicles in network virtual environment was controlled and operated by Asp.Net and SAI. The system running example showed that the developed Virtual Test System in network environment could analyze and simulate railway vehicle running stability effectively.
