摘要:

应用应力波理论, 采用围道积分的方法, 对受均匀内压的圆柱形空腔的应力进行分析, 得到在圆孔中作用一个突加载荷 时平面问题的解。再根据火炮内膛压力的变化, 拟合成动态载荷的曲线方程, 由应力波在炮管中的传播以及在内外管壁的反射 的理论, 通过计算机的优化计算, 获得了径向应力和环向应力沿管壁的分布, 并对厚壁圆筒在动态载荷下的应力分析作一些说 明。

Abstract:

This paper presents a surround - integral approach to the analysis of the stress created by well - distributed pressure in the cylinder in order to calculate the stress on its internal surface by theory of st ress waves when a sudden load is produced. According to the changing pressure of the cannon′s inner face ,the curve equa2 tion of dynamic load is worked out . With the aid of the theory of st ress wave ,the dist ribution of radius st resses and ring st resses was obtained by the optimized calculation in the computer ,and some explanations are given about st resses created by dynamic load in the cylinder.
