【Abstract】 In order to explore the influence of dynamic parameters of cam mechanism on the motion error of slave units,the measurement indexes describing the motion error of slave units of cam mechanism are defined by establishing a two-mass dynamic model of cam mechanism and considering the absolute error and shape error comprehensively. They are verified by some examples. The simulation curve after solving the equation with Matlab is used to obtain the influence law of dynamic parameters on motion error of cam mechanism′s slave units. The influence law is validated by parametric modeling and analysis in Adams software. The results are of great significance for the selection of dynamic parameters of cam mechanism.更多还原
