Numerical Analysis of Vibration Response of Flexible Multi-Body Dynamics on Mini-radar System

The mini-radar reflector servo system is studied by degenerating structural mode.A study is made of the different parts effect on the whole system mode.Based on the analysis,the first and second transmission system are chosen for a further study.According to actual situation,the system is subjected to the proper constraints.The simulating vibration analysis is made to study frequency response and transfer function.Results show the frequency bandwidth of the first transmission system satisfies the design requirement and its magnitude of angle velocity is much larger than that of angle displacement.While the frequency bandwidth of the second transmission system is narrow.And also its response magnitude of angle velocity is much larger than that of the angle displacement.The second transmission system is obviously 'weaker' than the first one.
