摘要
文中以某榴弹发射强度的数值计算为例,提出在强度较核中就高不就低的思想,即选取弹丸发射过程中最大膛压时刻弹丸敏感截面的轴向应力与按第四强度理论计算得到的有效应力的较大值,进行强度校核,以确保弹丸的发射强度。
In this paper,a shells launch stress code calculate result analysis method is presented and used in a example of a shrapnel launch stress cal.In fact,The method is a thought of choice higher stress between axis stress and effective stress resulted from the fourth stress theory to insure the shell launch process safety.
