摘　　要：根据虚功原理 ,应用Ritz方法 ,推导出简支边直角三角形正交各向异性板在横向载荷作用下的挠度二级近似计算表达式 ,分别给出了均布荷载和集中荷载作用下的近似计算结果 。On the basis of virtual work principle and the Ritz Method ,the deflection of orthogonal anisotropy right angled triangle plate bending with freely supported edges under the action of transverse load is approximately calculated on second grade, and the result is presented when the tranverse load is equi-distributed and concentrated respectively.The deflection at the figure center of equilateral triangle is also calculated when the material is isotropic.

关 键 词：正交异性板 虚功原理 挠度
