【摘要】 本文采用一种改进的Bingham模型描述汽车悬架中的非线性阻尼力,采用平方非线性模型描述轮胎刚度,通过平均法得到了两自由度汽车悬架系统振动的一次近似解和幅频响应曲线,并进行了数值验证。然后,研究了各系统参数对动态轮胎力的影响,可以为减小汽车振动对路面的影响,防止路面早期破坏提供理论依据。更多还原

【Abstract】 In this work,a revised Bingham model for MRF damping is used to describe the nonlinear damping force of vehicle suspension.The nonlinear stiffness of tire is square.An analytical solution for the two DOF vehicle system’s dynamical response is obtained by averaging method,which is verified by numerical solution.In addition,the effect of changing system model parameters on the tire force to road is also studied.The conclusions obtained from this work may be benefit to control vehicle vibration and avoiding pavement premature failure.更多还原
