摘要
从悬架系统所需要的最佳阻尼比出发,通过相关参数如车辆类型、簧上质量、车身固有频率、平安比、双向阻尼比、杠杆比的输入,在MATLAB软件环境下进行汽车筒式减振器设计,得到使悬架系统达到最佳阻尼匹配的减振器速度特性曲线。依据该曲线实现对减振器主要尺寸、节流阀系的设计,最后对设计得到的减振器模型进行阻尼特性仿真校验。由于整个设计过程都是在MATLAB软件环境下进行的,可以对输入参数、油路和数学模型等进行及时调整,极大地缩短了减振器的开发设计周期,降低其研发成本,具有一定的应用价值。
On the basis of the optimum damping ratio of suspension system, design of automotive telescopic shock absorber by using MATLAB can be achieved with parameters inputting such as vehicle type, unsprung weight, natural frequency of vehicle body, smoothness to safety ratio, double damping ratio, lever ratio, the speed characteristic curve of shock absorber with suspension system getting optimum damping match is obtained.According to the curve, the major dimension and throttle valves of shock absorber are designed, the simulation validation is conducted on the designed shock absorber model. The whole designing precess can be worked out by using MATLAB software,so the parameters, oil circuits and mathematical model can be adjusted at any time, it is of great application value in shortending development cycle and reducing the research costs.
