本文给出两个带有偏心(单面)加强环的大直径铝合金波纹园筒的弯曲试验结果。除了加强环的位置之外,两个园筒是相同的。一个园筒的环连接在外表面上,而另一个园筒的环连接在内表面上。两个园筒皆以总体失稳的形式翘曲,即波纹壁和加强环象一个合成壳那样翘曲。加强环在外表面的园筒的翘曲强度是加强环在内表面的园筒的2.3倍。两个园简的翘曲都发生在用计及加强环偏心影响的小挠度翘曲理论予示载荷的70％左右。
This paper presents the bending test results of two large-diameter aluminum alloy corrugated cylinders with eccentric (single-sided) reinforcement rings. The two cylinders are the same except for the position of the reinforcement ring. One cylinder ring is connected to the outer surface, and the other cylinder’s ring is connected to the inner surface. Both cylinders are warped in an overall destabilizing manner, ie the corrugated wall and the reinforcing ring are warped like a synthetic shell. The buckling strength of the ring on the outer surface of the reinforcing ring is 2.3 times that of the cylindrical ring on the inner surface. The warping of the two flats occurs around 70% of the indicated load with a small deflection warp theory that takes into account the effect of ring eccentricity.
