一种卫星天线的力限振动半经验系数研究
Evaluation of Force Limited Vibration Semi-empirical Constant for a Kind of Antenna
摘要
Abstract
The semi-empirical method,which is an important method to formulate force specifications for force-limited vibration tests,is introduced in this paper.Three successfully launched DFH-4 satellites＇ ground sine vibration tests are simulated by using the finite element method and their ground sine vibration test specifications.The fix points＇ acceleration and force responses of six antennas which are fixed on the three satellites are extracted from the simulation results,and the force limited vibration semi-empirical constants for this kind of antenna are evaluated.The results reveal the range of the semi-empirical constants for that kind of antenna,and they are useful for deriving force specifications for that kind of antenna in the future.关键词
