RIGID-FLEXIBLE COUPLED DYNAMICAL ANALYSIS OF ANTENNA PEDESTAL DRIVE SYSTEMS
天线座驱动系统刚柔耦合动力学分析

In order to analyze the dynamic characteristics of an antenna pedestal drive system, a new dynamic model called a rigid-flexible coupled model is proposed. In the new model, the deformation of spinnings and the supporting of bearings are considered. Gear tooth mesh is also taken into account based on an advanced contact model. The traditional multi-body transmission system model is improved, where the deformation of spinnings and the supporting of bearings are neglected. The simulation results reflect the dynamic characteristics of the antenna pedestal drive system, consistent with the theoretical analysis. The dynamic model and results may provide a guidance to engineering design and capability checkout.
