| Abstract: | The method of applying multibody system dynamics to the simulation of valve trains' kinematics and dynamics properties is presented, and used in the analysis of 4102QB engine's side-mounted valve train. The results show that it is needed to optimize its cam profile. Thus four style Ⅰ multiple cam profiles with different parameters, two polynomial profiles and one multi-cycloid profile are designed and applied to the valve train's multibody system dynamics model. By comparing the analysis results, a reasonable cam profile is obtained. |
