| Abstract: | The dynamic features of multi-shafting antenna stabilizing platform of ship-borne radars are analyzed with the finite element method.The antenna stabilizing platform of ship-borne radars is a complicated multi-DOF flexible system.The modal analysis of each part of the platform is carried out with the sub-structure method,and the results are analyzed with the coupling of boundary conditions.Besides,the dynamic response of the platform system with random load such as the excitation of servo drive system are calculated. |
