The tendency to design lighter structures and the increasing demands of customers for comfort, increases requirements of the resilient mounting of machinery (e.g. engines) in vehicles. The conventional passive vibration isolators might not be sufficient to reduce interior noise levels. Additionally, active isolation techniques can be used to obtain a better isolation performance. This research deals with the application of a combination of passive and active isolation (so-called hybrid isolation) for resilient mounting of machinery. Methods are introduced to model this kind of hybrid isolation system and in particular to investigate the different actuator configurations and sensor strategies of the active isolation part. |
