An explicit dynamic algorithm was adopted to perform detailed modeling and refined simulation for dynamic anti-shock problem of diesel engine.Individual and synthesized analyses were conducted so as to achieve the mechanical motion and dynamic shock simulations under different working conditions. High-performance computing (HPC)resources were 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 was analyzed to explore reasonable parallel acceleration strategy.The results show that such dynamic simulation method makes for the integrated kinetic and dynamic characteristics research of diesel engine,and HPC resource provides imperative guarantee for deeper investigation.
