摘要 针对差动自感式磁流变阻尼器中的绕线缸体结构参数对阻尼器工作磁场和感应磁场的影响进行电磁场有限元仿真分析。通过横向对比由导磁材料和不导磁材料制成的绕线缸体应用不同结构参数所产生的磁场强度和感应电动势,得到材料参数、结构参数与磁场的关系。分析结果表明:随着缸体厚度增加,工作磁场强度最大值降低,但在导磁材料缸体中的平均磁场强度明显提高;绕线区深度增加会显著提高感应电动势幅值,但会显著降低最大磁场强度、削弱磁化能力。根据以上结论,可分别从满足磁化强度要求及满足感应电动势幅值需求两方面入手,优化差动自感式磁流变阻尼器绕线缸体结构参数,达到满足预期条件的目的。 In order to solve the problems that the working magnetic fields and induced magnetic fields of the differential self-in- duced magnetorheological damper (DSMRD) were influenced by the structure parameters of the winding cylinder, the finite element model was established. By comparing the magnetic fields and induced voltage amplitude in different kinds of materials and structure pa- rameters of winding cylinder, the relationships among materials, structure parameters and magnetic fields were obtained. The simula- tion results show that the maximum values of the working magnetic field will decrease with the increasing of the thickness of the cylinder body, however, the average magnetic field in the cylinder body with magnetic material will increase. On the other hand, the induced voltage amplitude will increase with the increasing of the depth of the winding cylinder, but the maximum value of the magnetic field will decrease. Finally, the optimized DSMRD was obtained.
