point本文介绍了飞机全机有限元自然网格建模时蒙皮有效宽度的含义及作用,举例说明了现有方法对于含凸台蒙皮计算有效宽度时的不足,通过阐述有效蒙皮宽度作用的机理,提出了以体积等效来确定有效蒙皮宽度的新方法,并列出了一、二、三级凸台蒙皮有效宽度的计算公式,为便于计算,最后编制了对应公式的电子计算表格。
This paper introduces the meaning and function of the effective width of the skin in the modeling process of natural airplane with the finite element of the whole aircraft, and gives an example of the deficiency of the existing method when calculating the effective width of the skin with the boss. By elaborating the effect of effective skin width , A new method to determine the effective skin width with volumetric equivalent is proposed. The formulas for calculating the effective width of the skin of the first, second and third stage bosses are listed. For the convenience of calculation, the electronic formula corresponding to the formula Calculation form.
