摘要
为提高麦弗逊式独立悬架分析与设计效率,建立悬架受力分析以及进行刚度与阻尼计算的数学模型,给出按选定的偏频和相对阻尼比确定螺旋弹簧刚度和减震器阻尼参数的设计步骤,并研制了方便实用的麦弗逊螺旋弹簧悬架系统刚度和阻尼参数分析与设计计算软件.虚拟样机试验结果验证了数学模型和计算软件的正确性.
To improve the analysis and design efficiency of McPherson-strut suspension,a mathematical model of suspension based on force analysis and damping calculation was established.The design procedure of confirming parameters of coil spring stiffness and shock absorber damping based on designed offset frequency and relative damping ratio was put forward,and a set of special software of stiffness and damping parameter analysis and design for McPherson-strut suspension system was designed.The test results of virtual prototype verify the accuracy of mathematical models and calculating software on stiffness and damping characteristics analysis.
