铁道车辆运行稳定性虚拟试验系统研究

Running stability is a key performance indicator of the modern railway passenger vehicles .To solve the problem that there are some shortage in traditional evaluation method ,the paper, put forward a new way to evaluate railway vehicle running stability by using virtual prototyping and virtual reality technology.The system could not only ensure the calculation accuracy ,but also recreate the good real experiment environment through the establishment of a realistic virtual scenes and test virtual model of the railway vehicles.
