航天器随机振动试验振动台驱动力估算方法
An estimation method for the driving force of the shaker used in spacecraft random vibration test
摘要
Abstract
This paper proposes a new method of estimating the shaker force in the spacecraft random vibration test, based on an improvement of the classical modal contribution theory with consideration of the characteristics of the spacecraft random vibration test. It is shown that the method can be applied to calculate the vibration force under the non-white-noise exciting condition. Furthermore, a simplified method with three frequency bands is proposed for engineering estimations.关键词
