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 been attached importance to vibrant problems of slab all the while. The vibrant of slab is one of the hotspots in the vibrant researching field under all kinds of shape, structure, power and sorts of nonlinear factor. According to deflection function of the beam supported by elastic Faint of interior, the vibrant of slab simple-supported by elastic point of interior were analyzed and got better results, adopting multiple domain approach and Galerkin approach. The method is the same with vibrant analysis of slab simple - supported by elastic point of the interior to other boundary condition.
