Abstract

In order to meet the need of modern warfare, improve the accuracy and reliability of gun shooting, scholars have started research on the barrel bore parameter detection equipment. The centering device of detection equipment will directly affect the accuracy of it. A kind of adaptive diameter flexible expansion centering device was designed to ensure the centering accuracy of detection equipment. The process of expansion centering was simulated by using the ABAQUS finite element software non-linear analysis technology which can obtain the amount of taper-lock radial expansion under different expanding mandrel body axial displacement, find out the relationship between expanding mandrel body axial displacement with the amount of taper-lock radial expansion. That provides the basis for designing centering device. The stress concentration area of taper-lock during centering process was found out by analysis the stress value of flexible taper-lock under different expanding mandrel body axial displacement, which can put forward the optimization scheme. The phenomenon of stress concentration of taper-lock is reduced effectively through optimizing processing.
