Abstract：

The moving pair of pressure machine is often prone to produce movement gaps due to the recoil force, which leads to the increase of impact for mechanical system and the decrease of stability for stamping forming. Therefore, the dynamic modeling and simulation of moving pair clearance for triangular toggle press mechanism were optimized. Based on its working principle, the variation rules of motion characteristics for the executive connecting rod of upper triangle type and lower triangle type toggle press mechanisms were analyzed, and the displacement, velocity and acceleration of the upper triangle type were optimized by 30%, 59% and 390%, respectively, compared with the lower triangle type. Then, based on moving pair clearance model MLSD, a dynamic simulation model of upper triangular type toggle press mechanism with moving pair clearance was established by virtual prototype technology ADMAS, and the influences of collision and wear caused by moving pair clearance on dynamic characteristics of the mechanism were analyzed. The results show that when the relative clearance value of moving pair exceeds 20%, the operation of the mechanism is accompanied by great impact, as well as vibration and noise to a certain extent, which affects the stability of the mechanism. Thus, the research results provide theoretical basis for the structural design of toggle press press mechanism.
