For the research of the damping control strategy one type of controllable damper, magnetico-rheological ( mr ) damper, was constructed and tested, the damping force and displacement characteristic curves, the damping force and velocity characteristic curves are obtained, so that the damping force and voltage ( current ) model, or the damping coefficient and voltage ( current ) model can be further obtained 通過特性試驗,得到示功特性、速度特性,經(jīng)轉(zhuǎn)換得到阻尼器的阻尼力??電壓(電流)模型和阻尼系數(shù)??電壓(電流)模型。這樣在研究中,可以采用開環(huán)控制方式或力反饋控制方式實現(xiàn)阻尼力的控制。
