摘要
用分析力学法建立了九自由度轿车平顺性动力学模型,推导出动力学微分方程和加速度功率谱密度函数的计算公式.用MATLAB软件编写了仿真程序,并对某型号的轿车进行了仿真,分析了"人体-座椅"系统对轿车平顺性的影响.
In this paper, Analytical mechanics method is applied to establish a nine DOF dynamic car model. It is inferred to a differential equation set. The calculation formulas of acceleration power spec- trum density function are put forward. The paper has programed an emulator with MATLAB, The influences of the ＂occupant-seat＂ system on ride comfort are analyzed.
