Modeling and Analysis of 9 Degree-of-Freedom Plate Structure with Active Mounting System

摘要

In recent years, the automotive industry has been interested in NVH performance for increasing quietness and driving comfort. In this study, an analytical study is performed on an active mounting system with three active structural paths between source and receiver. The active structural path has a series connection structure of a piezoelectric stack actuator and a passive mount. A mathematical model for the overall model is derived and the force and phase of the actuator in each path are calculated for vibration isolation. In order to determine whether the vibration of the receiver is reduced, simulations are performed and it is confirmed that the vibration transmitted to the receiver through the active structure path is reduced.
