摘　　要：板的振动问题一直受到理论和工程界的重视,有关板在各种形状、构造、激励以及各种非线性因素下的振动问题仍然是振动研究领域的热点之一。以内部为弹性点支承简支梁的挠度函数为依据,采用multiple domain approach与Galerkin approach分析了内部为弹性点支承的四边简支矩形板的振动问题,获得了较好的精度。该方法适用于内部为弹性点支承的其它边界条件的简支板分析。The engineering and theory circles have attached importance to the vibration problems of the slab all the time. The vibration of the slab under all kinds of shape, structure, power and sorts of nonlinear factor is one of the hotspots in the vibration research field. According to deflection function of the beam simply supported by internal elastic point, the vibration of slab simply supported by internal elastic point were analyzed and some better results had been gained, adopting multiple domain approach and Galerkin approach. The method is suitable for vibration analysis of the slab simply supported by internal elastic point under other boundary condition.
