1) sheel body with thin wall and deep blind hole
薄壁深盲孔弹体
2) deep hole and thin wall
深孔薄壁
1.
Without the assumption of equally distributed load and thick-wall cylinder,the stress and deformation analysis were made on forward extrusion cavity die for deep hole and thin wall shell by FEM.
针对用于深孔薄壁件挤压的典型正挤压凹模,在不作厚壁圆筒简化并施加非均布载荷的情况下,采用有限元法进行受力和变形情况的分析,计算结果更接近于实际,并进而得到组合凹模配合面过盈量、切向应力和预紧圈外径的关系图。
4) thin-walls projectile
薄壁弹体
1.
A thin-walls projectile has been designed,and penetration depth of projectiles was evaluated by YOUNG Equation.
设计了一种薄壁弹体,采用YOUNG方程预估该弹体侵彻混凝土靶板的侵彻深度,采用SAMPLL程序预估轴向过载。
