摘要
基于分析力学基本原理并结合人体、车辆和路面的实际状况，从动力学普遍方程推导了人体—车辆—道路系统的１２自由度的振动力学模型。通过软件模拟，自动地生成有关非线性微分方程表达式，从而避免了复杂的手工推导；并通过数值分析，模拟了该系统对不同振动类型的响应，研究了人体和车辆的振动特征。所得结果对评价人体在振动车辆中的舒适性以及进一步深入研究该系统的振动，改善道路和汽车的振动特性有一定的指导意义。
On the basis of the theory of analysis mechanics, and combining with the real condition of the occupant, vehicle and road, the 12th degrees of freedom vibration model of the vehicle occupant road are formulated by using the equations of motions. A program is developed to create and analyze the non linear dynamical different equations automatically, avoiding the complex manual deduction. Through the numerical analysis, the response of the system to some kinds of vibrations are also simulated, and the vibration behavior of the occupant and vehicle are studied. The result for illustrating the comfort of human body under vibrating vehicle, and improving the vibration behavior of vehicle and road have guiding significance.
