本文提出以趋近预设的剖面积和剖面模数变化百分比为原则的全钢质夹层结构方案初选方法。首先，对夹层结构典型几何参数对剖面特征值的影响进行分析；其次，基于有限元分析软件MSC PATRAN/NATRAN，进行横向均布载荷作用下I型钢质夹层结构的承载特性分析与对比，研究主要设计参数对强度、刚度特性的影响。根据计算结果，对于均布载荷模式，夹层板整体弯曲应力是主要应力成份，远大于面板局部弯曲应力，夹层结构的上下面板和芯板呈整体变形的特点，同时基于多方案仿真分析结果验证了以趋近预设的剖面积和剖面模数变化百分比为原则的初选方法在确定夹层结构设计方案中具有一定的适用性。
Based on the principle of approaching the preset percentage of section area and section modulus, a preliminary selection method for the scheme of all-steel sandwich structure is proposed. Firstly, the influence of typical geometric parameters of sandwich structure on profile characteristic value is analyzed. Secondly, based on the finite element analysis software MSC PATRAN/NATRAN, the bearing properties of type I steel sandwich structures under transverse uniform load are analyzed and compared, and the influence of main design parameters on strength and stiffness characteristics is studied. According to the calculation results, the overall bending stress of the sandwich plate is the main stress component, which is much larger than the local bending stress of the panel based on the uniformly distributed load mode. And the overall deformation of the upper and lower face panels and core plates of the sandwich structure is the main characteristic. At the same time, based on the simulation results of multiple schemes, it is verified that the method has certain feasibility in determining the design scheme of sandwich structure.
