【摘要】 采用系统仿真方法及MATLAB软件,建立汽车减振器的详细模型,并进行仿真研究。模型能反映减振器的详细物理结构,如考虑油液特性影响、阀片刚度影响、摩擦力影响等。模型经试验校验/阻尼特性计算精度达90%,模型精度能满足实际工程问题的需要。经二次开发形成一套能进行参数化自动建模和仿真分析的软件系统,最终在汽车减振器设计过程中形成一套阻尼特性研究的系统完整的方法。更多还原

【Abstract】 The system simulation method and the MATLAB software were used to build a detailed model of a vehicle shock absorber. The detailed structure includes in the model, such as the hydraulic properties, the valve stiffness and the friction force. The absorber model was validated using test data and the precision is above 90%, which can fulfill the engineering requirement. An automated modeling and simulation software package based on MATLAB was developed, which could support a systematic research of vehicle shock absorbers in its design.更多还原
