The virtual prototype and dynamic model of 16VPA6STC diesel engine's valve actuating mechanism are built by using ADAMS software and the PRO / Engineer software, and the kinematics and dynamic characteristics of the diesel engine valve actuating mechanism are simulated The displacement, speed, acceleration, force and other parameters of kinematics and mechanics of the inclusive and exclusive valve, and other key components are obtained. Through comparing simulation data with the theory date to verify the accuracy of the model, then by changing rotate speed, the effect of valve speed with different rotate speed are analyzed. The result provides the foundation for further finite element structural analysis and optimization of system.
