Dynamic Simulation of High Speed Cam Mechanism (1st Report)

One Mass Model Obtained by Introducing Preliminary Experiment

Abstract

Dynamic simulation method of high speed cam mechanism is newly proposed to improve the defects of known analytical simulation methods. In this method, preliminary experiments on dynamic properties of cam mechanism itself are carried out in the same manner as its practical use, and their experimental results are analyzed by conventional FFT analyzer. On the basis of the natural frequency obtained as the above and other dynamic quantities by known methods, the dynamic properties are simulated by one mass model irrespective of the structure of its mechanism. Then, the follower motion and the cam contacting force are simulated by utilizing the model, and their simulated results are compared with their experimental results. As a result, it is ascertained that this simulation technique is usefull except follower jump phenomena.
