摘要: 民用飞机机身壁板为典型的“半硬壳式”薄壁蒙皮加筋结构,其压缩失稳应力由Johnson-Euler方程给出。压缩稳定性分析时考虑由机身长桁和有效蒙皮组成的复合截面,工程计算中常取有效蒙皮宽度为30倍蒙皮厚度(30),文章介绍了蒙皮有效宽度的算法和其影响分析。

Abstract: The strain transmits to the sensitive grid through a transition area whose range is related to the test strain, which introduces variations to the sensitivity coefficient of the electric resistance strain gauge instead if a commonly considered constant. This issue analyzes the test aberration due to the variations of the sensitivity coefficient ,and offers some methods to reduce its influence.
