中文摘要: |
冲击—接触计算模型在汽车碰撞、金属成型等的模拟计算中有着广泛的应用,鉴于冲击—接触计算过程复杂和计算量大,本文在分布式可扩展的并行计算平台上,设计并实现了冲击—接触的并行计算。算例证明,计算平台稳定可靠,算法简单实用,且具有较好的并行效率和可扩展性。 |
英文摘要: |
The contact\|impact model was widely used to simulate vehicle crashworthiness and sheet form process. Due to the considerable cost of contact\|impact computation, a parallel algorithm was presented and implemented on the distributed scalable parallel platform in this paper. From numerical examples, effectiveness and scalability are proved for the parallel algorithm. As well the stability of parallel platform is tested, which can be reliable to carry on parallel research and application in the developing countries because of its relatively lower cost than large parallel machine. |
