The impact analysis of the gaps in kinematic pairs on dynamic processes in cyclic mechanisms

Abstract

Cyclic mechanisms (cam, crank and others) are most vulnerable to the growth of dynamic (oscillatory) processes, especially at high speeds of their movement. Many factors affect the reliability and performance of these mechanisms, determined primarily by their dynamic characteristics. The main ones are the elastic-inertial and dissipative properties of the links, external forces acting on the elements of the mechanisms, as well as the gaps in the kinematic pairs of the links of the links. The paper studies impact of gaps in the kinematic pairs of link, design features of these links, all other things being equal, on the cyclic mechanical systems dynamics. Three computational models of kinematic pairs are considered in the article, the results of studying the influence these models parameters on the level of dynamic processes in the cam-lever mechanism during transfer workpieces between the cold-stamping automatic machine (CSAM) AB1818 positions.
