Semi-empirical Method for Force Specification in Force Limited Vibration Test
摘要
Abstract
The force limited vibration test can alleviate the over-testing phenomenon generated by the resonant frequency in the acceleration-controlled vibration test. Force specification estimation is a prerequisite for the force limited vibration test. The principle of force limited vibration test was introduced. And the calculation method for semi-empirical coefficient was derived by the two degree of freedom system. Furthermore, the force specification of some spacecraft payload was caculated in the random vibration test. The results show that this method is reasonable to estimate the force specification.关键词
