Abstract
A vibration insulating apparatus and a vibration insulating method disclosed herein is preferably applied to a vibration insulating mount disposed between a vibrating body and a mounting body. Here, the vibration insulating mount comprises a fluid chamber filled with fluid, an elastic support partly defining the fluid chamber, a movable member partly defining the fluid chamber, a resilient member resiliently supporting the movable member, and an actuator generating displacing force for the movable member according to a drive signal so as to change volume of the fluid chamber. Also, a reference signal indicative of a vibrating condition of the vibrating body and a residual vibration signal indicative of a residual vibration of the mounting body are generated. Thereupon, a driving signal is generated according to the reference signal and the residual signal and is output to the actuator so as to reduce vibration transmitted from the vibrating body to the mounting body by use of low-pass filter processing, and a cutoff frequency used in the low-pass filter processing is set in accordance with a state of a load applied to the vibration insulating mount.
