| 摘 要： | 以内部预充较高压力气体的封闭弹性薄壁圆筒为承载构件，讨论预充压力的强度对这种构件力学性能的影响。在外界载荷的作用下，内部充有较高压力气体的封闭弹性圆筒受力变形时容积发生改变，因而影响到内部气体压力的变化，对圆筒的受力与变形产生影响，使圆筒的刚度不再是常量。本文分析有内压封闭弹性圆筒承受轴向载荷时其刚度的变化情况。

| Abstract: | Taking a closing elastic thin wall tu be within preparing higher pressure air as loaded component,dis-cusses the influence of value of prep aring pressure on mechanical properties of this component.By the action of outside load the cubage of this tube c an change with distortion,thereby t he pressure of inside air may transfo rm,the stress and distortion of the tube may be infected,and the stiffness is con stant no longer.In this paper the change of stiffness of the closing elastic thi n wall tube with inside pressure by th e action of axial load is analyzed. |
