Research on the low-frequency vibration characteristics of the adaptive isolator based on MR damper

Based on the idea that combining traditional vibration-reduction components parallel with intelligent components, a new approach to the design of isolator which acts as vibration isolator and impact buffer is presented in this paper. With the application of magnetorheological damper (MR damper) and wire rope spring, an adaptive isolator is designed, whose dynamic characteristics is adaptive and controllable. By using this adaptive isolator into a structural system, the system vibration response or impact effects can be reduced. Furthermore, the experimental research on the isolator´s vibration characteristics is carried out. It shows that the performance of vibration reduction is favorable, especially in the low-frequency stage. The effect of vibration reduction is better than traditional components evidently.
