| 摘 要： | 讨论受内压椭圆封闭薄壁截面杆的小变形动力学性质。把内压产生的应力作为初应力,利用薄壁杆理论和初应力位形上附加变形的线性理论,研究相对初应力位形产生的附加变形控制方程,由此给出小变形动力学性质的定量分析方法和拉压、弯曲、扭转固有频率用内压表示的数值结果。

| Abstract: | Dynamic property of small deformation of thin walled elliptical bar under pressure was studied.The stresses under pressure were looked upon as initial stresses.Based on the theory of thin walled bar and linear theory of small deformation on the initial stressed configuration,the control equations of the deformation of the bar and analytical method were given.Relation between natural frequency and pressure was present in numerical result. |

| Keywords: | pressure thin walled elliptical bar dynamics |
