The explicit dynamic algorithm is adopted to perform detailed modeling and refined simulation for dynamic anti-shock problem of diesel engine. Individual and synthesized analyses are conducted as to mechanical motion and dynamic shock simulation with different working conditions. High-performance computing(HPC) resources are utilized to meet the challenge of large scale computing requirement due to debugging and load cases. Through multi-core parallel computing and performance data comparison on different platforms, each parallel speedup phenomenon is analyzed to explore reasonable parallel acceleration strategy. The results shows that such dynamic simulation method makes for integrated kinetic and dynamic characteristics research of diesel engine, and HPC resource provides imperative guarantee for solving and deeper investigation.
