摘要

磁流变液 (Magnetorheological fluid, MRF) 作为一种磁场响应型的智能流体, 在阻尼减振领域受到广泛关注。MRF的流动状态对阻尼器中的振动控制起到关键作用。本文通过多物理场模拟对MRF在阀式阻尼器中的流动行为进行了研究, 目的在于全面的了解磁场如何改变沿磁流变阻尼器通道内MRF的速度分布和压降。通过创建通电线圈实现磁场的产生, 随后通过调整电流改变磁通密度。磁场计算表明, 在阻尼器流道最窄处, 磁场几乎垂直于MRF流动方向。接着, 基于流体流动、电场以及磁场间的多物理场耦合计算, 计算分析了不同磁场下MRF在流道中的流速变化以及压力等特性。结果表明, 在MRF流动方向垂直于磁场方向的流道最窄处, MRF的流动使其受到体积力, 进而使流速出现降低的趋势, 在流道左右两侧产生较大压力差。此外, MRF的流速随磁场的增大而减小, 磁场强度从0. 5T增加到1. 5T时, MRF流体在流道最窄处的流速降低大约0. 18m/s。

Abstract

Magnetorheological fluid (MRF) is a kind of magnetic field responsive intelligent fluid, which is widely concerned in the field of damping and vibration reduction. The flow state of MRF plays a key role in vibration control in dampers. In this work, the flow behavior. of magnetorheological fluid (MRF) in a valve damper is studied through multi-physical field simulations. The objective is to comprehensively comprehend the influence of the magnetic field on the velocity distribution and pressure drop of the MRF within the damper channel. The magnetic field is generated by creating an electrified coil, and the magnetic flux density is subsequently changed by adjusting the current. The magnetic field calculation shows that the magnetic field is almost perpendicular to the MRF flow direction at the narrowest part of the damper channel. Next, based on the coupling calculation of multiple physical fields between fluid flow, electric field, and magnetic field, the flow velocity and pressure characteristics of MRF in the flow channel were calculated and analyzed. The results indicate that at the slit where the MRF flow direction is perpendicular to the magnetic field direction, the volume force acting on the MRF reduces its flow velocity, resulting in a significant pressure difference between the left and right sides of the flow channel. Additionally, the flow rate of MRF exhibits a decrease as the magnetic field strength increases. When the magnetic field strength increases from 0. 5T to 1. 5T, the flow rate of MRF fluid at the narrowest part of the flow channel decreases by about 0. 18m/s.
