摘要

为研究液压自紧身管的力学性能

利用ANSYS软件对普通身管发射时的各项应力进行数值模拟;对9个不同液压作用下的身管的液压自紧进行了数值模拟

得到液压自紧身管的各项残余应力;再对9个不同液压自紧后的身管施以相同的膛压

模拟了液压自紧身管在发射时的各项应力.最后对普通身管和液压自紧身管在相同膛压作用下的等效应力进行了对比.通过对比等效应力分布

找出了最佳的液压范围和最佳的超应变.

Abstract

To study the mechanical property of hydraulic autofrettaged gun tube

the stresses of ordinary gun tube firing were simulated by ANSYS.Also

the numerical simulations of the hydraulic autofrettage were run for nine different hydraulic pressures and the residual stresses of hydraulic autofrettaged gun tube were obtained.Nine different hydraulic gun tubes were applied to same gun chamber pressure and the stresses of hydraulic autofrettaged gun tube firing were simulated.The Von-Mises stresses of ordinary gun tube and hydraulic autofrettaged gun tube applied to same gun chamber pressure were compared.The optimum hydraulic range and super strain were obtained by comparison.
