摘要
针对工业管道系统中DN200三通部件在复杂流体载荷下的力学响应问题,本文开展了不同夹角及入口流速组合工况下的流固耦合特性研究。基于SolidWorks建立三维实体模型,结合流体域压力分布计算,实现结构应力场耦合分析。研究揭示了流速与夹角对三通壁面压力、结构应力应变及变形的影响规律,验证了工况参数与材料性能的匹配性。结果表明:流速升高导致流场扰动与速度梯度加剧;高流速与大夹角工况加剧流体扰动与结构应力集中,三通分支连接处为关键受力区域。四种工况下,三通管的流固耦合响应均处于低水平,验证了结构在该流体参数范围内的稳定性。
Conduct a study on the fluid structure coupling characteristics of DN200 three-way compo-nents in industrial pipeline systems under complex fluid loads,considering different angles and inlet flow velocity combinations.Building a 3D solid model based on SolidWorks,combined with fluid do-main pressure distribution calculation,to achieve structural stress field coupling analysis.The study re-vealed the influence of flow velocity and angle on the pressure,structural stress-strain,and deforma-tion of the three-way wall,and verified the matching between operating parameters and material prop-erties.The results indicate that an increase in flow velocity leads to disturbances in the flow field and an intensification of velocity gradients;The high flow velocity and large angle working conditions in-tensify fluid disturbance and structural stress concentration,with the three-way branch connection be-ing the key stress area.Under all four operating conditions,the fluid structure coupling response of the three-way pipe is at a low level,verifying the stability of the structure within this fluid parameter range.
