Abstract: Shock analysis framework of shipboard diesel engine was set up, based on shock analysis methods development of shipboard equipments and diesel engine as well as structural features of diesel engine. Two important sho ck analysis methods of diesel engine, which were multi-body dynamics method and finite element method, were analyzed. There were some important contents of shock analysis of diesel engine which were nonlinear problem, shock environment and shock trials. Some key components should be studied in detail were mentioned, which were movement assemblies, gear, bearing, cam, important screws, clearance and pipe.
