Abstract

The embodiment of the invention discloses a method for determining whether the bolt type selection is correct or not. The method comprises the steps of obtaining a vibration signal of a bolt under theactual working condition through an acceleration sensor arranged on a connecting plate; establishing a finite element model of the bolt and the connecting plate; carrying out parameter configurationon the finite element model, wherein the parameters are determined according to the actual working conditions; performing data processing on the vibration signal, and taking the processed data as theinput data of the finite element model; outputting the maximum stress of the bolt through the simulation calculation of the finite element model; and comparing the maximum stress with the parameters of the bolt of a national standard to determine whether the type selection of the bolt is accurate or not. According to the technical scheme, the situation that the fault is fed back to the engineers only after the bolt goes wrong, so that the bolt type selection period is shortened, and the efficiency is improved.

Description

technical field [0001] The present disclosure relates to the technical field of bolt selection, in particular to a method for determining whether the bolt selection is correct. Background technique [0002] Bolts have the advantages of simple structure, convenient installation and disassembly, and low cost, and are widely used in various fields. But the disadvantage of bolts is that under the condition of vibration, shock, load fluctuation and excessive temperature difference, the bolt connection tends to loosen and cause mechanical failure. Therefore, when selecting bolts in engineering, it is necessary to consider the material, performance and how to prevent loosening of the bolts. In the prior art, the bolt type is usually selected based on experience, and to judge whether the bolt type is selected correctly, it is often necessary to wait until the bolt is deformed or loosened before reaching the conclusion that the bolt type is wrong. Using this method to determine the...
