摘要
研究了模拟振动环境中螺纹连接在不同预紧力下的松动情况。对实验数据的差量分析发现,从信号差值的有效值的增大或减小可以判断螺纹连接松动的情况。
The looseness situations of threaded connection under various pretightening force in simulative vibration environment have been researched.By analyzing experimental data difference,the threaded connection looseness situation could be estimated according to increase or decrease of signal difference effective value.
