摘要

中国空间站（以下简称空间站）大量科学仪器设备需要松不脱螺栓锁紧。针对空间站主动隔振器研制过程中松不脱螺栓锁紧诱发的频率漂移问题，探索了空间站主动隔振器锁紧状态非线性连接动力学机理建模与试验验证。对基于松不脱螺栓的隔振器锁紧释放装置进行力学分析，并根据松不脱螺栓接触面应力的非线性分布建立基于Iwan模型的系统等效动力学模型，分析动力学响应的非线性特性。研制空间站主动隔振器样机进行正弦振动试验，验证所建立动力学模型的准确性和有效性，为空间站精密科学设备环境适应性设计提供参考。

Abstract

A large number of scientific instruments and equipment in the space station need to be locked by unloosening bolts. Aiming at the problem of frequency drift induced by unloosening bolt locking during the development of active vibration isolator for space station, the dynamic mechanism modeling and experimental verification of nonlinear connection of active vibration isolator for space station in locking state are explored.The mechanical analysis of the locking release device of the isolator based on the unloosening bolt is carried out, and the equivalent dynamic model of the system based on the Iwan model is established according to the nonlinear distribution of the stress on the contact surface of the unloosening bolt, and the nonlinear characteristics of the dynamic response are analyzed.The prototype of the active vibration isolator of the space station is developed for sinusoidal vibration test to verify the accuracy and effectiveness of the established dynamic model, which provides a reference for the environmental adaptability design of the space station precision scientific equipment.
