摘　　要：建立了规则非对称正交层合梁在拉伸和弯曲耦合时的位移微分方程 ,其耦合效应依赖于铺层的组数和材料主向弹性模量的比值。当铺层组数大于 8时 。The differential equations of displacements have been developed for l aminate beam under the coupling of tension and bend. The coupling effect depend s on the number of laminate series and the ratio of main directional elastic mod ulus of material. As the number of laminate series is more than 8, the coupling effect can be neglected, and normal-asymmetrical laminate beam can be treated as normal - symmetrical laminate beam.

关 键 词：层合梁 位移 拉伸 弯曲 耦合效应 应变
