The health state of the reciprocating mechanism is crucial to the reliability and maintenance of the system.Taking the reciprocating mechanism of a large-calibre naval gun launching system as the specific research object,a set of simulation methods to simulate the reciprocating wear process was established by adopting the improved Archard wear model based on the cyclic jumping technique,which achieved the accurate prediction and analysis of the wear process.The simulation shows that the loop jumping technique significantly improves the simulation efficiency and reduces the consump-tion of computational resources,that the dynamic changes of the wear volume and contact pressure are obtained from the model,and that the key time nodes,wear rate and wear depth predicted by the model are consistent with the experimental situation,which provides reliable data support for the opti-mal design and maintenance strategy of the reciprocating mechanism.
