| Abstract: | On the basis of dummy prototype technology, the dynamics model of valve train system of a marine diesel engine is established by the use of Virtual Engine software. By the use of discrete flexible dynamics model, the simulative calculations on kinematics and dynamics characteristics of valve train system are carried out, and the dynamic performance of valve train system has been evaluated. After simulation, some techniques are used to improve the design of the roller tappet. The simulated results show that the dynamic performances of the valve train system are good. The contact stress of the improved roller tappet is lower than the original and the reliability of the roller tappet is improved. |
