基于Solidworks的Y形岔管应力变形和流场特性分析及体型优化
|
摘要
结合辽宁省某输水工程沿线隧洞出口设置的Y形岔管,运用Solidworks软件中的Simulation和Flow Simulation模块对岔管进行了有限元静力分析和CFD数值模拟计算,提出了更为合理的Y形钢岔管体型。计算结果表明:对于Y形月牙肋岔管,当肋宽比≤0.12时,其变形较大值一般位于两支管和月牙肋相贯处,成上下对称分布,且位移较大、较集中,应力较大值位于肋板内侧中心位置、管壳上下两侧靠近肋板端部位置和主支管交界位置;当肋宽比≥0.24时,其变形较大值一般位于岔管上下两侧主管和支管相贯处,成左右对称分布,且位移较大、较集中,应力最大值位于管壳和肋板端部交界处的管壳上;肋板的宽度和厚度对管壳的应力、岔管内水的流态和水力损失影响均很小,增加肋板的宽度和厚度能有效减小肋板本身应力。计算结果可为类似岔管的设计和推广提供一定的参考价值。
Both Simulation and Flow Simulation modules within Solidworks software were used to build finite element static and CFD numerical simulation for a Y-type branch pipe.The Y-type branch pipe was chosen because it was used for the tunnel exit of a water delivery project in Liaoning Province..The results showed that,for the Y-type internal crescent-rib branch pipe,the large deformation is generally located at the intersection of the two branches and the crescent-rib when the rib breadth ratio is≤0.12.The distribution was symmetric around its horizontal axis,and the displacement was large and concentrated.The greater stress was located at the inner center of the rib,the upper and lower sides of the shell near the end of the rib and the junction of main pipe and branch pipe.When the rib breadth ratio was≥0.24,the large deformation was generally located at the intersection of the main pipe and the branch pipe on the upper and lower sides of the branch pipe.It was also symmetrically distributed in the left and right,and the displacement was large and concentrated.The maximum stress was located on the shell,which was near the end of the rib.The width and thickness of the ribs had little effects on the stress of the shell,the flow states of the water and the hydraulic loss in the branch pipe.Increasing the width and thickness of the ribs can effectively reduce the stress of the crescent-rib.The results can provide a reference for the design and promotion of similar branch pipes.
