摘要：To calculate the residual stresses of swage autofrettage thick-walled cylinder, some simulations were run for different friction coefficients. It was found that the friction coefficient did not influence the residual stress and plastic radius. Thus, it is unnecessary to consider the effect of the friction coefficient on plastic radius and residual stress. Also utilized all equations of the spacial axisymmetric problem and boundary condition and continuity condition of swaging, the formula of plasic radius and the stress and strain of thick-walled cylinder and swage were deduced. Eventually by using the results of elastic analysis of unloading gun barrelthe formula of residual stress of gun barrel was derived. In oder to verify the accuracy, the theoretical value and the results of experiment were compared. The theoretical value shows good agreement with results of experiment.
