Vehicle traffic accidents are causing increasing public concern, and are perceived and identified as a major cause of injury and death, resulting in substantial social and economic cost to the community. Finite element simulation is an effective and low-cost method that improves the crashworhiness and is applied to reduce the R&D cost and shorten the design time in the developing stage of vehicle design. Vehicle impact is a complicated nonlinear dynamic contact process because automobile structures experience dramatic impact loads in very short time (usually in 100 ms). The research presented in this paper deals with explicit nonlinear finite element calculation with domain decomposition for vehicle crashworthiness simulation. This is very important for vehicle design. Parallel computing is an efficient solution method to speedup and enhance the solving ability of large-scale numerical simulation. In this paper, a cost-effective domain decomposition method based on contact balance is presented, and the algorithm flowchart including contact computing is provided, and the parallel computing process and communication overhead are analyzed. Furthermore, scalability of the parallel computing method on different hardware platforms, the SGI Onyx 3800 and the ShenWei cluster, is studied. Finally, the effect of different domain decomposition strategy on vehicle crashworthiness simulation computing efficiency is presented. To end users, the research results should provide a reference for vehicle design and choosing appropriate hardware platform and computing software.
