车辆座椅悬架用磁流变阻尼器的阻尼特性实验研究

摘要

在分析磁流变阻尼器的工作原理和简化模型的基础上,以座椅悬架用磁流变阻尼器为实验对象,在不同控制电流和不同激振频率输入下,对磁流变阻尼器的阻尼特性进行了台架实验研究.结果表明,该磁流变阻尼器耗能效果明显,而且阻尼力随着控制电流、激振频率的增加而增大,并趋于平衡.%Based on the analysis of working principle and simplified model with magneto-rht ological damper, targeted magneto-rheological damper used in vehicle seat suspension, under different control currents and different excitation frequency inputs, test studies on the damping characteristics of magne-to-rheological damper are completed. The results indicate that the magneto-rheological damper has a good effectiveness for energy dissipation. The damping force increases with the increasing of control current and excitation frequency and tends to balance.
