【摘要】：为了改善长管拖车气瓶瓶肩的受力状态,尝试在长管拖车气瓶瓶肩添加一种矩形环凸形结构,运用ANSYS软件分别模拟了环凸形结构离肩距为10 mm~55 mm、长度为40 mm~130 mm、宽度为6 mm~24 mm范围内的最大位移、最大等效应力和最大轴向应力,最后与长管拖车气瓶瓶肩不添加环凸形结构的结果对比分析.结果表明:长管拖车气瓶瓶肩添加环凸形结构可以改善气瓶的受力状态,减小最大位移大约3.3%,最大等效应力大约10%,最大轴向应力大约5%,气瓶受力状态与环凸形结构位置、长度和宽度大致呈线性关系,这种设计为长管拖车气瓶的优化设计提供了参考.
[Abstract]:In order to improve the load state of the cylinder shoulder of the long tube trailer, a rectangular ring convex structure was added to the cylinder shoulder of the long tube trailer. The distance from shoulder to shoulder is 10 mm~55 and the length is 40 mm~130 mm by ANSYS software. The maximum displacement, maximum equivalent stress and maximum axial stress are obtained in the width range of 6 mm~24 mm. Finally, the results are compared with the results of the long tube trailer cylinder shoulder without ring convex structure. The results show that the long tube trailer cylinder shoulder with ring convex structure can improve the stress state of the gas cylinder. The maximum displacement is about 3.3%, the maximum equivalent stress is about 10 and the maximum axial stress is about 5. The stress state of the cylinder is approximately linear with the position, length and width of the ring convex structure. This design provides a reference for the optimization design of long tube trailer gas cylinders.
