| 摘 要： | 通过对椭圆形封头与筒体连接处的受力分析,计算了筒体与椭圆形封头连接处的边缘力、边缘力矩和边缘应力,结果表明,边缘应力恒为负,这能改善内压作用下边缘连接处的受力状况。结合制造因素,提出了椭圆形封头直边设置的要求。

| Abstract: | Through analysis the receiver force between elliptical head and cylinder at juncture location , the force and moment and stress in boundary region were calculated The result indicates that the boundary stress is constant negative value,under interior pressure it can improve the receiver force state in boundary zone Base on this discovery,as well as consider manufacture aspect factor , some proposal about setting skirt length of elliptical head were put forward |
