由于层压板梁的各向异性,载荷下结构响应和刚度特性难以确定。为了解决有限元方法在进行复合层压板梁的结构分析时参数确定的难题,提出了一种层压板工字梁的应力分析方法,并在MATLAB上编程实现,通过与理论计算值和有限元软件ANSYS分析结果进行对比,证明该方法可行,且适合于进行参数化研究设计。
Due to the anisotropy of the laminated beam, the structural response and stiffness characteristics under load are difficult to determine. In order to solve the problem of determining the parameters of the finite element method in the structural analysis of composite laminates, a method of stress analysis of the I-shaped laminates is proposed and programmed in MATLAB. ANSYS analysis results to prove that the method is feasible and suitable for parametric research design.
