Abstract: A cam driving a lumped inertia through an elastic slider-crank follower linkage with its actuator, a D. C. motor, has been considered in this work. An iterative procedure utilizing the finite element method developed by Midha et al. (1978) is used to synthesize the cam profile to produce a desired output motion at a given design speed and damping ratio. The elastic deflections induced by the large inertia of the linkage operating at a fluctuated high speed of the driving cam are taken into account in synthesizing the cam profile. Responses of the synthesized linkages are simulated and found to be satisfactory at the design conditions.
