摘　　要：用有限元软件MARC建立了具有脱层和无脱层的两端固支层合板模型,并进行了模态分析。文中分别研究了双金属粘接、复合材料与金属粘接、复合材料与复合材料粘接三种类型的层合板脱层对其固有频率的影响,并绘制了脱层与固有频率关系曲线图,为工程应用提供了科学依据。In this paper, the lamination board models with fixed ends were established with MARC and the mode analysis was carried on. The bimetal cementation, the compound material and the metal cementation, the compound material and the compound material cementation three types of lamination boards delaminates on its natural frequency had been separately studied and delaminating with the natural frequency relations diagram of curves had been drawn up.
