摘要
研究了磁流变液在阻尼通道处的流变特性,利用COMSOL、Fluent软件对阻尼通道进行了流体仿真,分析了阻尼通道处磁流变液的速度、压力分布情况。结果表明:环形槽可以有效提高阻尼器的阻尼力,当深度为0.55 mm、宽度为2.2 mm,间隙为1.4 mm时,可使阻尼器的阻尼力达到最大,同时也证明了该理论模型的正确性。
The rheological properties of magneto-rheological fluid at the damping channel was studied. The COMSOL, Fluent were used to simulate fluid properties and the velocity, pressure distribution of magneto-theological fluid at the damping channel were ana- lyzed. The results show that the annular groove can effectively improve damper damping force, and the damping force of the damper can achieve maximum when the depth is 0. 55 ram, the width is 2. 2 ram, the gap is 1.4 mm, also proves the theoretical model is correct.
