横隔式夹层梁由上、下面板及中间的横隔板组成 ,在工程中有一定的应用 .利用能量变分原理及连续化分析方法 ,推导了夹层梁的微分方程 ,并且根据微分方程 ,求得了两端简支夹层梁的级数解 .最后 ,通过数例与有限单元法进行比较表明 ,这一方法简单而有效复合材料横隔式夹层梁的分 The diaphragm sandwich beam is composed of upper and lower panels and intermediate diaphragms. It has certain applications in the project. Using the energy variation principle and continuous analysis method, the differential equation of the sandwich beam is deduced, and according to the differential equation, The series solution of simply-supported sandwich beams at both ends is obtained. Finally, the comparison between several examples and the finite element method shows that this method is simple and effective for the separation of composite sandwich beams.
