| 摘 要： | 采用有限元软件对磁流变阻尼器间隙磁场进行仿真计算,并设计正交试验对剪切阀式磁流变阻尼器的结构参数进行了优化研究.分析了阻尼间隙磁场强度的影响因素,并对主要因素进行了细化研究.计算结果表明,在考虑阻尼器边界漏磁的前提下,磁极宽度是影响阻尼间隙磁感应强度的主要因素,阻尼间隙磁感应强度随着磁极宽度的增大线性降低,随激励电流线性增大.因此在设计大阻尼力减振器时,宜将阻尼器活塞分为三阶段或更多阶段.

| Abstract: | The gap magnetic induction intensity of magnetorheological fluid damper was calculated by finite element methord. Orthogonal test was conducted to optimize the magnetic pole structural parameters of the damper. The factors affecting the gap magnetic induction intensity were analysed and the major factor was analysed in detail. It can be found out that, the width of magnet pole is the main factor after considering leakage magnetic flux. The magnetic induction intensity of damper gap decreases linearly with t... |
