摘要
本文以Ｔｉｍｏｓｈｅｎｋｏ－Ｍｉｎｄｌｉｎ假设及Ｈａｍｉｌｔｏｎ原理为基础，建立了中厚板的非线性运动控制方程。应用参数增量法求解了四边简支矩形板在纵横谐载共同作用下的非线性动力稳定性问题，并对影响其动力稳定性的若干因素进行了讨论。
Based on Timoshenko-Mindlin kinematic hypotheses and Hamilton's principle,the governing motion equations for geometrically nonlinear middle-thick rectangular plate are derived. By using incremental parameter method, the nonlinear dynamic stability of simply supported plate under in-plane and transverse harmonic loads is analysized. The effects of some parameters on the dynamic stability are discussed.
