摘要
基于磁流变液的流变特性,设计应用于减振系统的双出杆磁流变阻尼器,详细讨论了双出杆磁流变阻尼器设计过程中主要构件参数的确定以及磁路尺寸计算。通过Work bench有限元软件对饱和磁路问题进行分析,表明活塞轴心区域和磁流变液工作区域的磁路基本同时饱和,验证了设计尺寸的合理性,从而提高阻尼器的工作效益,获取较大出力。基于Bingham模型,将实验测试得到的力学性能数据与理论计算数据进行对比,结果保持一致,验证了设计方案的可行性。
Based on the rheological properties of magnetorheological fluid(MRF),the two-way pusher-overmagnetorheological damper(MRD)is designed for damping systems.The determination of main components parametersand magnetic circuit size in the design of the MRD is discussed.The saturation magnetic circuit problem is analyzed bymeans of the finite element code Workbench.The results show that the magnetic circuits of the piston core area and the MRFwork area are basically saturated at the same time.Thus,the rationality of the size design is confirmed and the workingefficiency of the MRD is raised.The results of the experimental test and the results of the theoretical computation based onthe Bingham model are found to be consistent.The feasibility of the design is verified.
