摘要
本文分析形状不规则旋转平板的应力状态．利用完备的双重三角级数作为试函数，运用数学规划加权残值法求得旋转板的位移和应力．数字计算结果表明尺寸不均匀旋转结构上的应力分布状况与尺寸匀称结构有很大的不同，因此更应注意其安全问题．
This paper presents the strase analysis of rotating plates with trregular shapes. Thecontributions of displacements and stresses in the plates are obtained by the use of themathematical programming on method of weighted residual and the complete test function of double trigonometric series. The numerous results show that the stress contributions in rotating structuresof irregular shape are much different from regular structures. Thus more attention should be paidto the safety of the structures in engineering.
