| 摘 要： | 本文对中心带轴匀速旋转圆盘在均布压力作用下的受力及变形问题进行了摄动分析，得到了受载条件为Ｊ＾２／ＪＨ＜＜１时，圆盘应力及形变的渐近解。其形变渐近解为Ｗｈｉｔａｋｅｒ函数形式比较表明，渐近解与Ｃｈｅｂｙｓｈｅｖ数值解有较好的一致性。

| Abstract: | In this paper, the problem of a steadily spinning disk under uniformly distributed pressure is investigated by the use of perturbation method. The asymptotic solutions of stresses and deformations under the loading condition of JV2/JII< <1 is obtained. The asymptotic of deformation can be described with the Whillakcr function. Comparation shows that the asymptotic solutions are in good agreement with the Chebyshev numerical solutions. |
