| 摘 要： | 以航空等工业领域用板因制造因素所造成的初始横向小变形为背景，抽象出了初始几何不平整矩形正交各向异性板的力学模型。从理论和实验的角度研究了在四边均为简支时正交各向异性弹性薄板因初始不平整度对振动频率造成的影响。

| Abstract: | The mechanics model of orthorotic plastic thin plate is based on the plates which are used in industrial fields so as arospace fields.Due to manufacturing and other factor,there are small initial transversal deformation on the plates.The influence of initial geometrical imperfection on the vibration frequency of orthorotic plastic thin plates is described in this article in the term of theory and expriment. |
