Anti-shock design of shipboard equipment is an important part to ensure warship vitality. In this paper, based on the multi-body system discrete-time transfer matrix method, shock response calculation model of a diesel generator set is established, and the generation method of system overall transfer matrix based on the topological structure is established. Parameter study of anti-shock of the diesel generator set is carried out. Based on the standard of BV043/85, the shock resistance parameters of the diesel generator set subject to different shock environment are studied. The results show that the multi-body system discrete-time transfer matrix method is suitable for the study of shock resistance of shipboard equipment, and the shock resistance design of the diesel generator set meets the requirements. The research method in this paper can also be used for reference in the field of aerospace, vehicle transportation and other fields.
