力限振动试验技术进展综述

Overview on research progress of force limited vibration technology

力限振动试验技术在国外航天飞行器振动试验中广泛开展,主要目的是减轻或抑制振动试验中的过试验现象。介绍了力限振动试验技术的国内外进展情况,并回顾了解决振动试验中抑制过试验的方法,重点针对力限振动试验条件设计方法中力限谱的设计方法及力限参数获取方法方面,对力限振动试验技术进行了综述。最后,对力限振动试验技术的应用前景进行了展望。

In vibration test of aerospace flight equipment overseas, force limited vibration technique implement abroad. Its main purpose is mitigating or restraining the ＂overtest＂ phenomenon in vibration test. The paper present the development of force limited vibration test technique in overseas and domestic domain, and review the solving methods of ＂overtest＂ in history. Mainly for acquiring force limited power density spectrum and parameters of the specification design methods In force limited vibration, force limited vibration testing technique is summarized. Finally its application is prospected.
