1/4车辆磁流变悬架非线性振动分析
Analysis on Nonlinear Vibrations of Quarter Vehicle Suspensions with Magnetorheological Damper
【摘要】 采用非线性Bingham模型,研究基于磁流变阻尼器的1/4车辆悬架的非线性振动特性.在合理假设的基础上,首次得到简谐激励下悬架簧上和簧下质量的非线性振动响应,并给出磁流变阻尼车辆悬架的簧上和簧下传递系数的理论解,并用数值模拟的方法验证了理论分析的正确性.
【Abstract】 The nonlinear Bingham model is adopted,and the nonlinear vibrations of quarter vehicle suspensions with magnetorheological(MR) dampers is analyzed.After reasonable assumptions and formulations,the harmonic responses of the nonlinear dynamic system are firstly obtained.Then the formulas of spring and unsprung transmittances for vehicle MR suspensions are presented.Numeric simulations verify the validity of the theoretical analysis.
