| 摘 要： | 基于分层理论并在壳厚方取二次位移插值函数来推导出粘弹层合壳的动力学方程,得出的简支粘弹层合壳自由振动频率和损耗因子与已知文献数据吻合较好,且能够计算协调的横向应力.在低频振动时,横向剪应力是造成层合板脱层的主要原因;高频时,横向正应力在脱层破坏中起主要作用.结果表明本文中所采用的算法、算式及所编写的程序是可靠的.

| Abstract: | Based on theories of layerwise,the governing equations for dynamic response of viscoelastic laminated shell were derived by using the quadratic interpolation function for displacement in shell thickness. The vibration frequencies and loss factors were given for free vibration of shell with the simply supported boundaries. The vibration frequencies and loss factors show good agreement with data of literature.And the reasonable transverse stresses can be obtained.The transverse shear stresses are the main fac... |
