[Objectives]As bolts and pins are important connector for installation of shipboardequipments,using properly simplified method for anti-shock evaluation can reduce the computation costand improve the simulation efficiency.[Methods]On the basis of time domain analysis on the anti-shockproperty of shipboard equipment,a marine generator with a large amount of connectors(e.g. boltss andpins) is chosen as research object. Firstly,installation simulation of connection with bolts and pins iscarried out to obtain t...
