| 摘 要： | 本文研究了电流变液和弹簧所组成的粘弹性型活塞式结构的振动.实验表明,随外加电场强度增加,结构振动幅值减小,系统谐振峰向高频方向移动.这种效应在振动低频区段更为显著.据此可制作阻尼可控结构.

| Abstract: | In the paper, the vibration property of viscoelastic piston cylinder operator is studied, which contains the electrorheological (ER) fluid and a common spring. The experimental results show that the amplitude of vibration decreases and the resonance peak moves to higher frequency as the strength of electric field increases. This effect is obvious at lower frequency band. Following the result, a controlled damper can be made up. |
