变刚度气门弹簧组固有特性对配气机构性能影响的研究

An Investigation into Effect of Intrinsic Property in Variable Stiffness Valve Spring Group on Dynamic Performance of Valve Train

通过试验研究，介绍了不同类型、不同压缩状态的变刚度气门弹簧组的固有特性变化规律，及其对配气系统动态特性的影响，为配气系统动态理论分析和变刚度气门弹簧的造型设计提供依据。

The intrinsic property change law of the variable stiffness valve spring group in various types and different compression states and its effect on dynamic performance of valve train are presented in this paper. It provides a basis for the0retically analysing the dynamic performance of the valve train and designing the variable stiffness valve spring.
