Computer Aided Kinematic and Dynamic Analysis of Cam and Follower

Cam and follower are widely used in regulating, opening and closing of valves (inlet and exhaust) in the internal combustion engines. Proper design of cam and follower is required for perfect tuning between opening and closing of valves with cam shaft speed. In this paper, the complete kinematic and dynamic analysis of cam and follower is done and critical angular speed is determined for each design to predict when the follower jumps off the cam. Analytical method is used, as it is more accurate and less time consuming and if programmed for the complete solution. The dynamic force analysis determines the cam contact forces and values of kinematic parameters at which the design fails. The analytical calculation is done in excel sheet for both kinematic and dynamic analysis of cam follower system for any rotational speed and angle of rise. Cams are commonly used in opening and closing of valves in internal combustion engines. Both the inlet and outlet valves are regulated using cam and follower. The study of cam and follower mechanism becomes important for desired and required performance of the engines. In this paper, complete kinematic and dynamic analysis of cam and follower mechanism is carried out using analytical method. The equations for governing motion of the follower have been taken from the literature.(3) The kinematic analysis of mechanism helps in answering many questions related to motion of the follower. In this present work displacement, velocity and acceleration values are calculated at each 10
