摘　　要：针对桌面端铁道车辆动力学仿真软件在计算资源利用效率、多任务并行等方面存在的不足,基于云仿真理论和模型,提出以网络为基础的铁道车辆动力学云仿真系统框架并开发相应的原型系统。上述系统将算法求解器抽象为服务接口,通过Web技术提供跨平台能力,将WebGL渲染与云渲染技术应用到模型查看和结果可视化。以某型号动车组列车动力学仿真过程验证该系统,结果表明,上述系统能够提供传统桌面端仿真软件的大部分功能,在实时的结果渲染、可扩展性、多人协作效率和硬件计算资源利用效率等方面具有明显优势,系统框架对其它行业仿真软件向云仿真迁移具有一定的借鉴意义。s the algorithm solver as a service interface,provides cross-platform ca-pabilities through Web technology,and applies WebGL rendering and cloud rendering technologies to model viewing and result visualization,The system was verified by the train dynamics simulation process of a certain type of EMU,and the results show that:the system can provide most of the functions of the traditional desktop simulation software,and has obvious advantages in real-time result rendering,scalability,multi-person collaboration efficiency,and hard-ware computing resource utilization efficiency;the system framework has certain reference significance to the migration from simulation software to cloud simulation in other industries.
