均匀外压下的锥壳减速机试验

有关壳结构屈曲性能的研究日益增多,尤其是锥壳。然而,有关细长柱端壳体减速机的足尺模型和实际模型的屈曲性能试验研究还较缺乏。试验研究和分析3个锥壳减速机在均匀周边压力下的屈曲性能。进行有限元模拟和理论分析,比较屈曲荷载和变形模式。在研究范围内,收集足尺锥壳减速机的有关数据。

Experiments on Conical Shell Reducers Under Uniform External Pressure

In previous studies,aproliferation of research work has been undertaken on the buckling behavior of shell structures particularly conical shells.Nonetheless,no experimental studies are found in the literature on the buckling of a full and real configured model of a slender shell reducer with two cylindrical end boundaries.To this end,buckling behavior of three conical shell reducers under uniform peripheral pressure was investigated and evaluated experimentally in this paper.In addition,relevant FE simulati...
