摘要
螺纹连接的接触特性呈现明显的非线性特征,它的状态直接关系到结构的可靠性。本文简述了螺纹连接状态辨识的方法,从动力学建模、模型参数识别、无模型信号处理方法等几个方面介绍了螺纹连接状态识别的研究现状,针对螺纹连接状态识别有待解决的问题提出了一些建议。
Contact property of screw-connected joint is obviously nonlinear. Its condition is immediately related to reliability of structures. This paper introduces the method of condition identification for the screw-connected joint in the aspects of dynamic modeling, model parameter identification, non-model signal processing method, etc. Some suggestions for condition identification of screw-connected joints are proposed.
