| 摘 要： | 本文用Levy法和有限差分法相结合,研究了两对边简支、另两对边为三种典型支承任意组合的六种弹性矩形薄板在切向均布随从力作用下的动力稳定性问题.通过数值计算,给出各种支承板的失稳形式及相应的临界载荷,并分析了泊松比、板的边长比对板的失稳形式及临界载荷的影响.

| Abstract: | The daynmic stability of six typical rectangular plates with two opposite edges simply supported under the action of uniformly distributed tangential follower force is investigated by using Levy's method and the finite difference method. Type of instability of the plates by flutter or divergence, critical load and flutter frequency are obtained. Studied are the effects of the Poisson's ratio and aspect ratio on the dynamic stability of the plates. |
