摘要

以单自由度非线性磁流变阻尼器系统为研究对象，通过变换磁流变阻尼器的外加电压，对系统实施半主动开-关控制。在分析系统运动特征基础上，给出了系统的运动微分方程，利用平均法进行分析求解。根据奇异性理论得到系统基的普适开折以及特例情况下的转迁集。并将磁流变阻尼器应用到转向架横向动力系统的振动控制中，分析了系统参数对幅-频特征曲线以及稳定性的影响

Abstract

Nonlinear single degree of freedom magnetorheological damper system is study in the paper. The system can implement the semi-active on-off control strategy through the transformation of the MR damper voltage. In the based of analyzing the dynamic characteristics of the system, it gives the differential equation system. And the solution is obtained by the averaging method. According to singularity theory, the universal unfolding of system and transition set under a special circumstances are studied. Then the magnetorheological damper is applied in the lateral bogie dynamic system as the vibration controller. And the effects of system parameters on amplitude frequency curve and stability are analyzed in detail
