摘要
本文按非线性大挠度弹性屈曲理论对广泛应用于工程中的“圆板─扁圆锥壳─圆环板”组合结构的弹性突跳现象进行了分析，并对典型算例用积分法与MWR－CM的伽辽金法相结合的方法进行了数值计算，结果表明了几何参数对弹性突跳的影响。本文工作可为工程应用设计提供一定的依据。
The structure composed of circular plate, conical shallow shell and annular plate is used widely in the engineering. And one of its important characteristic is elastic jump. Thisarticle analyzed this structure by the nonlinear theory of elastic buckling. Besides, it used integral method and Galerkin method to calculate some bypical examples. The resultS highlight the effects of geometric parameter on the elastic jump characteristic of this strUctUre. The article can provide a basis for the engineering design.
