Abstract:

The theory of modulation was applied to the existing cam curve. With the adjustment and control effect of modulation function on the shape of cam curve, the mathematical model of cam curve modulated with the multi-objectives  optimization was established, which consisted of characteristic values of the cam curve. In addition, the solving procedure of the model using particle swarm optimization technique was present. A new method that modulated and optimized cam curve was proposed. To illustrate the method, a corrected sine acceleration movement cam profile was modulated and optimized. The optimization example illustrates that the presented new method can adjust the shape of cam curve, improve dynamics characteristic of cam profile and achieve cam profile with good synthetic performances．

Key words: cam curve, modulation, particle swarm optimization, multi-objective optimization
