通过对夹芯板的理论研究,得到不同面材夹芯板抗弯承载力的统一表达形式,并引入剪力分配系数的概念,采用有限元方法对不同面材的夹芯板进行回归分析,得到其关于板厚和面板厚度的表达式。最后,将基于此设计公式的计算同不锈钢、秸秆、铝面各种夹芯板的试验值等进行比较,验证设计公式的可行性,从而将各种不同金属面夹芯板抗弯承载力的设计公式用一个统一的公式表达。
Through the theoretical study of the sandwich panel, the uniform expression of flexural capacity of different sandwich panels was obtained, and the concept of shear distribution coefficient was introduced. The sandwich panels with different surface materials were analyzed by the finite element method. Get its expression on thickness and panel thickness. Finally, the calculation based on this design formula is compared with the test values of various sandwich panels made of stainless steel, straw and aluminum, and the feasibility of the design formula is verified, so that the flexural capacity of various metal-faced sandwich panels The design formula is expressed in a uniform formula.
