提出了一种基于旋转磁流变阻尼器和电磁感应装置的自供电磁流变座椅悬架。通过将自供电部件应用于MR座椅悬架，半主动座椅的操作成本便宜得多，因为不需要外部能量来控制MR阻尼器。本文在绪论部分介绍了座椅悬架的结构、设计和分析。在MTS试验机上进行了自供电座椅悬架的性能试验。采用鲁棒控制算法对自供电磁流变座椅悬架进行了控制，并对座椅悬架在简谐激励和随机激励下的减振性能进行了测试。试验结果表明，在合理的控制下，自供电磁流变座椅悬架可以改善乘客和驾驶员的乘坐舒适性。
This paper proposes a self-powered magnetorheological (MR) seat suspension on the basis of a rotary MR damper and an electromagnetic induction device. By applying the self-powering component to the MR seat suspension, the operation cost of the semi-active seat is much cheaper because no external energy is required to control the MR damper. In this paper, the structure, design and analysis of the seat suspension were presented following the introduction section. The property tests of the self-powered seat suspension were conducted using an MTS machine. A robust control algorithm was developed to control the self-powered MR seat suspension and the vibration attenuation performance of the seat suspension was tested under two different vibration excitations, i.e. harmonic excitation and random excitation. The testing result verifies that the self-powered MR seat suspension under proper control can improve the ride comfort for passengers and drivers.
