Taking theoscillatory slider as a moving reference frame, relative motion relations of the cam-rocker mech-anism are established in the kinematic analysis. A non-linear equation is solved by indirectmethod to obtain its numerical solutions expressed in algebraic power series for the six-barlinkage. In dynamic analysis, the authors have set up dynamic equations for the entire mecha-nism to find the solutions. From the results of dynamic analysis, it can be seen that the mecha-nism is suitable for operation at high speed and under heavy load.展开更多
