内燃机配气机构系统刚度的虚拟设计
Virtual design of rigidity for valve train system in internal combustion engine
摘要
Abstract
In order to define the stiffness of the two-mass valve train model which is the key parameter of the valve train system, the finite element calculation was carried out by using different methods of compartmentalizing component based on the creation of the 3D models of every component of the valve train of WD615. The stiffness values of various valve train systems were calculated by using the simulation method mentioned above. After the calibration of the test system, the simulation results were tested by using the technique of laser measurement. The simulation and test result showed the reasonability and accuracy of the FEM method and the measurement error was limited to 5%. It coule be concluded that there was a quadratic polynomial increase between the valve train stiffness and the quality of the valve while the natural frequency of valve system waved between 30 000 to 50 000 times/min based on the statistical results. This research could provide the theory basis of developing the new valve train system.关键词
