| 摘 要： | 为解决常规减振器控制力小减振效果不理想的问题,设计了一种基于磁流变液—泡沫金属两相结构的新型减振器,在减振器工作原理的基础上推导出了其阻尼力模型。利用MATLAB软件中的Simulink模块建立了该阻尼力的仿真框图,并进行了实例仿真分析,理论分析及仿真结果表明:外界激励、泡沫金属的等效孔数和孔径对阻尼力影响较大,而等效孔长度对阻尼力几乎无影响,这为磁流变液—泡沫金属减振器的设计提供了有益的参考。

| Abstract: | In order to solve the questions that the general shock absorber controlling force is small and the effect of decreasing vibration is not ideal,a new shock absorber based on MRF and foam metal was designed and the damping force model was established on the basis of the shock absorber operating Principle. The damping force simulation diagram of Simulink was established and the simulation analysis of a example was carried out,the theoretical analysis and simulation result indicate that the influence of the ext... |
