磁流变阻尼器在多维减振平台上的应用
|
摘要
自行设计并制作了一款磁流变阻尼器,通过对实验数据和特征曲线的分析,研究了该阻尼器的磁场强度和阻尼性能,验证了该阻尼器应用于半主动控制的优越性.根据减振平台主体机构的并联机构机型的选择原则,以三平移减振平台为例,提出了将磁流变阻尼器应用于多维减振平台上的设想,并构思了初步方案,为此类阻尼器应用于多维减振平台提供了数据基础和技术支持.
A magnetorheological damper is designed and manufactured independently.Through the analysis of experiment data and characteristic curves,research on its magnetic magnitude and damper performance was conducted.Then,the advantage of applying this damper in semi-active control is validated.According to the principles of selecting parallel mechanisms in the main mechanism of vibration absorber,taking three DOF vibration absorber as an example,the assumption of applying MRD in multi-DIM vibration absorber is put forward.This paper provides data basis and technical support for the application of this damper in multi-DIM vibration absorber.
