Abstract

The invention provides a pre-tightening force change curve processing method, and a thread anti-loosening performance testing method and device. The processing method comprises the following steps: dividing an obtained pre-tightening force change curve into a plurality of change stages according to a preset interval; fitting the pre-tightening force change curve of each change stage to obtain a change slope corresponding to each change stage; and according to a preset characterization slope determination rule, obtaining a characterization slope for determining the loosening condition of a to-be-tested threaded connection structure. The pre-tightening force change curve is obtained, change stage division is carried out, the pre-tightening force change curve if fitted to obtain the change slope of each change stage, and the characterization slope for characterizing the loosening condition of the threaded connection structure is obtained according to the preset characterization slope determination rule, so the technical blank that whether the threaded connection structure is loosened or not cannot be accurately judged at present is filled up, and quantification and evaluation of the threaded connection structure are facilitated.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a pretightening force variation curve processing method, a thread anti-loosening performance testing method and a device. Background technique [0002] The threaded connection structure is widely used in machinery, transportation, construction and other fields due to its low cost, convenient disassembly and assembly, and large connection force. However, in actual use, due to the existence of complex working conditions such as various vibrations and shocks, the threaded connection structure is prone to loosening and failure. Therefore, engineers often use some anti-loosening measures to improve the anti-loosening performance, such as using anti-loosening fasteners. In order to make the optimal choice between different anti-loosening measures, or to optimize the design and manufacturing process of specific anti-loosening fasteners, it is necessary to quantitatively evaluate the an...
