摘　　要：本文将栅格夹心三明治板等效为均匀夹层板,应用Reissner夹层板理论,采用傅里叶级数法,将局部荷载转化为均布荷载形式,利用均布荷载的求解结果,对四边简支条件下几种局部荷载作用下三明治板的弹性小挠度变形进行了分析,可以得到理论解,通过与有限元分析进行比较,两者结果吻合良好。Sandwich plates with truss cores have been assumed as a sandwich panel with uniform cores. Then the bending deflection of sandwich plates under local loads were studied with Reissner sandwich panel theory by means of the Fourier series expansion. The closed-form solution of a simple supported sandwich plate was calculated, and it agreed well with 3D finite element analvsis.
