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 the vehicle builders and component manufacturers effectively carry out the crash safety collaborative design simulation and protect their own intellectual property under the distributed heterogeneous environment, this paper analyzes the prototype of the automobile collaborative collision simulation, proposes and establishes the automobile based on GOS 2.1 Collision safety collaborative simulation grid system, the service of model auto assembly and result decomposition is constructed by using Web service technology, the collaborative collision simulation Web service workflow is established by using WS-BPEL and BPEL4 People, the dynamic sharing of computing resources is realized, The intellectual property of the vehicle manufacturer and the component manufacturer.Finally, the collision simulation of a car was run in the system to verify its feasibility.
