With the social development and scientific and technological progress in order to improve product quality and productivity, as the core components of the cam mechanism of the machinery and equipment necessary to further improve the design level, on the basis of the analytical method designed to carry out the study of computer-aided design and application. Therefore, to carry out the analysis of motion of the cam mechanism to reveal the kinematic performance, the optimal design of the institutions and dynamics analysis has important practical significance. This paper first introduces the overview of the development of the cam mechanism, put forward the background and significance of the topic, then pointed out that research trends at home and abroad and domestic universities cam mechanism experiment is only limited to the measurement and analysis of motion parameters, and then put forward to the most commonly used in real life cam based design of an innovative test platform to conduct a series of experiments to design, analysis and testing of the cam mechanism. Cam profile design computer software to draw on the basis of the analytical method. Cam processing method with the most common line cutting, with CAXA line cutting software to assist write code. Platform to measure disk cam, cylindrical cam, direct-acting the motion characteristics of the follower and oscillating follower cam mechanism. The restoring force of the driven member with constant gravity gravity reply movable straight track with a linear guide, and further improve the measurement accuracy. In the experimental Taichung sensor design, allows students intuitive to observe the follower velocity, acceleration; richer, in order to allow the measurement data of the bench, and rotary encoders, can be observed in the experimental stage, and research the cam mechanism in the operation of the speed of the input shaft, so that the entire bench more powerful experimental richer, the movement of the cam mechanism is also helpful.
