    摘要:

    以包含三层黏弹性材料、二层纤维增强材料和金属外层的多黏弹性层纤维增强(MVFLM)层合板为例,建立其在基础激励作用下的动力学模型。将坐标系设置在层合板结构的中心层,使用高阶剪切变形理论(考虑多个黏弹性层的剪切应变影响)和经典层合板理论分别对纤维层和金属层进行建模,进而获得MVFLM层合板的位移场函数;将基础激励等效成均布惯性力载荷,基于能量法获得系统的动能、势能和外力功,并利用正交多项式法表示边界条件对应的振型函数,成功求解具有多个黏弹性层的MVFLM层合板的固有频率、模态振型和振动响应;分别通过与已有计算结果进行对比以及实例测试,验证了所建立的动力学模型的有效性。

    Abstract:

    A dynamic model of MVFLM plate with three viscoelastic layers,two fiber reinforced layers and metal outer layers isestablished.The coordinate system is set in the central layer of the laminated plate structure.The high-order shear deformation theory is used to consider the shear strain effect of multiple viscoelastic layers,the classical laminated plate theory is employed on themodelling of fiber layers and metal layers,consequently the displacement field function of MVFLM plate can be obtained.Thebased excitation is equivalent to the uniform inertia force load,the kinetic energy,potential energy and external work of the systemare obtained based on the energy method,and vibration mode functions corresponding to the boundary conditions are expressed bythe orthogonal polynomial method.In this way,the natural frequencies,modal shapes and vibration responses of MVFLM platewith multiple viscoelastic layers can be successflly solved.The validity of the dynamic model is verified by comparing with the results of the literature calculation and instance tests.
