| 摘 要： | 基于电流变液体特殊的阻尼可调的力学性能,针对电流变隔振器的结构特点,论述了其工作原理,采用键合图方法仿真和模拟评价隔振系统性能的两个参数--动刚度和响应滞后角.从理论的角度证明了电流变隔振器在低、高频段均有良好的隔振效果,该隔振器可利用"智能"的电流变液体,依靠外电场的控制及时准确地调控液体的粘度,实现对系统阻尼力的干预调节,达到发动机宽频带范围内主动隔振的目的.

| Abstract: | Based on the particular characteristics of the Electrorheological Fluids (ERF) tunable damping, the structure of ER isolator and its working principle are discussed. The two estimative parameters of isolation system-dynamic stiffness and loss angle are determined applying bond graph theory to dynamic simulation and modeling. It is proved that ER isolator will work well in both in the low and high frequency zones. The "smart" ER fluid can tune its viscosity instantly with controllable electric field and thereby gain ends in active isolation and enlarge the isolation frequency domain efficiently by measuring the system damping. |
