摘要
根据发动机磁流变型悬置的结构,建立了磁流变型悬置的力学模型和数学模型,应用MATLAB/SIMULINK对磁流变型悬置在低频激励下的动特性的影响进行研究。分析了电流强度和激励幅值、橡胶主簧等效面积、激励频率对磁流变悬置动特性的影响。分析结果表明:磁流变悬置较液压悬置在低频大振幅工况下能获得更大的阻尼和刚度。
The mechanical model and the mathematical model were established according to the structure of magnetorheological（ MR） engine mount,and the influence of dynamic characteristics under low frequency excitation was studied by using MATLAB / SIMULINK. The influences of current intensity,excitation amplitude,the equivalent area of rubber spring and the excitation frequency on the dynamic characteristics of MR mount have been analyzed. The results show that the MR mount can gain greater damping and stiffness than the hydraulic mount under the conditions of low frequency and large amplitude.
