| 摘 要： | 针对海洋工程结构物在工程上的应用逐年增多的趋势,采用连续介质力学一般理论,由弹性动力学基本方程出发,将运动方程与静态屈曲问题的本征方程相结合,推导了承压结构的压力载荷与结构固有圆频率相关联的运动方程.得到了屈曲问题的临界荷载与固有频率之间的关系表达式,最后给出了耐压结构稳定性的无损检测分析方法.

| Abstract: | In allusion to apply year after year manifold trend of the ocean engineering structure,the commonly theory of continuum mechanics was adopted to derive the associated motion equation of pressure and structure natural frequency by elasticity dynamics essence equation for compressed structure.The relation expression of flexure problem between critical load and natural frequency was given.The no damage testing method of compressed structure stability was given. |
