摘　　要：分别对网格尺寸、表层薄板厚度、肋的截面高度和夹层板总厚度等四种参数进行改变,得出楼盖的自振频率,分析对刚度的影响,进而得出影响正交斜放空腹夹层板楼盖的自振频率的主要因素。The four parameters of grid size,thickness of surface sheet,height of section of rib and total thickness of sandwich panel are changed respectively. The natural frequency of the floor is obtained,and the influence on the stiffness is analyzed,so as to make the conclusion of the main factor in the natural frequency of the empty sandwich panel floor.

关 键 词：自振频率 网格尺寸 空腹夹层板厚度 上下肋高度 表层薄板厚度
