【Abstract】 In order to improve the polishing performance of domestic grinding head,the acceleration shock was simulated by using ADAMS software during the motion of CAM mechanism with MT268 grinding head. It was proposed that improvement of the cam outline could be achieved through the sine acceleration law. The simulation results show that the improved cam could effectively reduce the acceleration shock from the model seat; meanwhile,with the analysis of the gap between cam and roller by using the software parametric analysis function,the reasonable installation position of the cam,as well as a concrete structural improvement plan,was obtained.更多还原
