초록 ▼

A mount assembly is provided for mounting a component, such as an engine, to a vehicle for active control of vibration. The assembly includes first and second mounting members and, an intermediate insert with first and second elastomeric systems connecting said first and second mounting members with the intermediate insert in between. An actuator in parallel with said first elastomeric system provides vertical force to said first elastomeric system to provide a relatively soft vertical rate. A controller operates the actuator in response to sensed vibration so that the vertical force tends to avoid or cancel it. A relatively high fore/aft and lateral dynamic rate of the first system protects the actuator. The second elastomeric system connects the second mounting member with the intermediate insert and exhibits a relatively high vertical rate and a relatively soft fore/aft and lateral rate. One or more sensors feeds data to a controller that analyzes the vibrations to determine the harmonics thereof. The controller then constructs one or more output waveforms and feeds them to the actuator so that a force is applied across the first elastomeric system between the first mounting member and the intermediate insert, thereby tending to produce the relatively soft vertical rate for component isolation and noise suppression.

A mount assembly for mounting a component to a vehicle providing active control of vehicle vibration, comprising: a first mounting member; a second mounting member; first and second dynamic means connected in series between said members for vertical isolation and motion control and fore/aft and lateral isolation and motion control respectively; means for sensing component vibration; actuator means in parallel with said first dynamic means for providing a substantially vertical force to said first dynamic means; and control means for operating said actuator means in response to said sensing means so that said vertical force tends to cancel said sensed vibration; whereby a relatively soft vertical rate is effected by said first dynamic means and said actuator means for noise suppression, as well as effective component motion control.
