A simulation model has been developed to estimate belt load by replacing the layout (L/O) around the engine synchronous drive belt and cam pulley with a simple vibration model based on the spring-mass system. Verification of the belt load generation mechanism was made between calculated and measured belt load values based upon DOHC engines with different number of cylinders. Another verification was made for the belt load generation mechanism in the SOHC engine with different initial belt tension value. This report describes the specifications of our simulation model and the results of verification.
