摘要
The buckling performances of stainless segmented toroidal pressure hulls were studied under uniform external pressure. The adopted segmented toroidal pressure hulls used was as 70.5 mm, the wall thickness was as 1.319 mm and the circumferential radius of rotation was as 134 mm. Six segmented toroidal models were manufactured and the geometric measurements, hydrostatic external force tests and numerical calculations were carried out. Then, the buckling behaviors of segmented toroidal pressure hulls were analyzed, along with the effects of the segmented angles and ring parameters on the buckling were investigated. The results show that the segmented angle is not influential on the buckling loads of segmented toroidal pressure hulls. The critical buckling load value remains constant and close to that of the connecting elements when the width and thickness of the segmented ring reach a certain threshold value. © 2021, China Mechanical Engineering Magazine Office.
