汽车碰撞安全协同仿真网格系统

Vehicle collaborative crash simulation based on grid system

为了在分布异构环境下,使整车商与部件商能有效进行汽车碰撞安全协同设计仿真,并保护各自的知识产权,分析了汽车协同碰撞仿真的原型,基于GOS2.1提出并建立了汽车碰撞安全协同仿真网格系统,利用Web服务技术构建了模型自动装配、结果分解等服务,使用WS-BPEL和BPEL4 People建立了协同碰撞仿真Web服务工作流,实现了计算资源的动态共享,保护了整车商与部件商的知识产权.最后通过某汽车的碰撞协同仿真实例在系统中运行,验证了其可行性.

In order to make OEM and suppliers would carry out collaborative design simulation of vehicle crash safety more effectively under distributed environment,and to protect their intellectual property,this paper analyses the process of vehicle crash simulation,designs and builds a vehicle collaborative crash simulation grid system based on GOS2.1,which implements model assembling and result extraction services using Web services technology.It also builds collaborative crash simulation Web services orchestration based on WS-BPEL and BPEL4People.In the end,a vehicle side impact example runs in the system and checks its feasibility.
