本期论文广场栏目中,灰锁局部结构的有限元分析一文,以灰锁设备为例,对设备中的局部斜接管进行了应力分析及疲劳评定。由分析结果得出,内倒角半径越大,线性化路径的壁厚越薄,峰值应力越大,越不利于容器抗疲劳失效。船用运输钛罐的有限元分析、换热器试压环的优化设计、膜式分油机系统流程设计、顶张式立管长期涡激振动疲劳分析、浮筒式平台上部模块总体布置研究、导管架吊装吊点的设计分析、固定式海洋石油平台吊机底
In the article column of the essay, the finite element analysis of the local structure of the gray lock takes the gray lock as an example to analyze the stress and fatigue of the local miter pipe in the equipment. From the analysis results, the larger the inner chamfer radius, the thinner the linearized path wall thickness, the greater the peak stress, the less conducive to the container anti-fatigue failure. Finite element analysis of marine transport titanium tank, optimization design of pressure test ring of heat exchanger, design of membrane type oil separator system, fatigue analysis of long-term vortex-induced vibration of top-riser, research on overall arrangement of upper module of pontoon platform, Hanging point design analysis, fixed offshore platform crane offshore
