摘要：In this study, a numerical investigation on the dynamic characteristics of a reciprocating mechanism with clearance considering parameter uncertainty is presented. For this purpose, complex space motion between parts is converted into simplified motion of basic component based on the proposed mass substitution model. The contact model in motion parts is established using the Lankarani-Nikravesh model, and the friction effect is considering using a modified Coulomb friction model in the proposed methodology. The comparisons between the numerical results, experimental ones, and virtual simulation ones are carried out. The results show that the proposed methodology has a higher efficiency and calculated precision to predict the dynamic behavior of a reciprocating mechanical system with clearance. In addition, the effects of interval clearance and initial force in the gas-operated chamber on the dynamic behavior are analyzed, respectively. Also, the interaction of two factors is discussed to improve the motion stability.
