摘要

针对某型复合材料螺栓连接件，研究其在高温环境下的振动特性，为表征其松动特性提供理论和试验依据。本文利用振动控制系统，温度控制系统和非接触式激光测量系统实现了1000°C高温环境下的复合材料螺栓连接件振动试验。并利用短时傅里叶方法提取高温环境下的振动响应特征量，结合复合材料连接件的振动基频，二倍频幅值和二倍频与基频幅值的比值对连接结构的松动状态进行综合评判。试验结果表明，在连接件宏观松动现象非明显情况下，本文所提评判方法能够综合评估复合材料螺栓连接件在高温振动环境下的松动特性。

Abstract

Here, vibration features of a certain type composite bolted connector were studied under high-temperature vibration environment to provide theoretical and test basis for judging its loosening features.Using a vibration control system, a temperature control system and a non-contact laser measurement system, vibration tests of the connector under 1 000 ℃ high-temperature environmentwere conducted.The short-time Fourier transformation method was applied to extract its vibration response characteristic quantities under high-temperature environment.The fundamental natural frequency, the amplitude of the second natural frequency component and the amplitude ratio between those of the second one and the fundamental one of the bolted connecter were used to judge its loosening state.The test results showed that under the condition of its macroscopic loosening phenomenon being not obvious, the proposed method can be used to comprehensively evaluate loosening features of the composite bolted connector under high-temperature vibration environment.
