The primary goal of this work is to design a novel magnetorheological damper with selectable performance parameters to improve the environmental adaptability of vibration systems equipped with such a damper and to provide a new idea for the design of magnetorheological dampers. The feasibility of the new idea is verified in both principle and experiment. The conceptual design, working principle analysis, magnetic design and prototype development of the magnetorheological damper are carried out. The damper prototype is tested on the dynamic testing system and the results show that the field-off force, peak force and dynamic range of the damper vary with the working modes, which proves that the performance parameters of the proposed damper are selectable during usage. Compared to conventional magnetorheological dampers, this new type of damper has a greater potential to achieve a large adjustment range. In addition, the damper can automatically switch the working channel in accordance with actual stroke, thus improving the response of the vibration system to unanticipated increasing loads.

三种工作模式的多通道旁路磁流变阻尼器设计

这项工作的主要目标是设计一种具有可选性能参数的新型磁流变阻尼器,以提高配备这种阻尼器的振动系统的环境适应性,并为磁流变阻尼器的设计提供新的思路。新思路的可行性得到了原理和实验的验证。进行了磁流变阻尼器的概念设计、工作原理分析、磁性设计和样机研制。阻尼器样机在动态测试系统上进行测试,结果表明阻尼器的场外力、峰值力和动态范围随工作模式而变化,证明所提出的阻尼器的性能参数在使用过程中是可选择的。与传统的磁流变阻尼器相比,这种新型阻尼器具有更大的潜力,可以实现较大的调节范围。此外,阻尼器可根据实际行程自动切换工作通道,从而提高振动系统对意外增加载荷的响应。
