CAD of Parallel Indexing Cam Mechanism Based on Matlab

摘要

Cam mechanism with variable inputting speed, its driving force will change along with the profile of cam, thus make the design of cam mechanism becomes a difficult problem. In this paper, a three-dimensional CAD system of cam based on Matlab was developed. A CAD program is developed to simulate the profile of the plate cam. The system brings about the integration of calculate and draw, enhances quality and efficiency of cam mechanism design and create a favourable condition for movement simulation and machine of the cam. Based on tabu search algorithms and Matlab, optimization simulation has been done. The change of acceleration became more stable and the optimization effect was better than that of genetic algorithms. One design example is demonstrated in this paper.
