摘要
Abstract
To meet the application requirements of airborne radars, a multi-DOF passive vibration isolation platform based on parallel mechanism with redundancy protection ability is designed. The principle design of the vibration isolation platform is introduced, and the multi-DOF motion ability of the vibration isolation is proved based on screw theory and modified Kutzbach-Grubler formula. The capability of damping vibration of the platform is simulated in the case of possible failure based on the design of redundancy protection. The simulation proved that the vibration isolation platform under the failure condition can still protect the radar from overlarge vibration, which can improve the survivability of the radar.关键词
