摘　　要：迷宫式调节阀的节流特性依赖于节流碟片流道结构,合理设计节流碟片可以有效改善调节阀性能。提出一种适用于节流碟片流道优化的设计流程,基于流体动力学理论与数值仿真方法,结合NSGA-Ⅱ多目标优化算法,实现节流碟片流道的三维结构优化设计。以节流碟片流道中流体最高速度和流量为优化目标,流道的几何尺寸作为输入量,将计算流体力学与NSGA-Ⅱ算法联合,获得了优化后流道三维结构集合。优化设计的节流碟片结构可以有效降低流体的最大流速并提高流量,改善流道的流动特性,为相关流体传动元件的设计提供参考。The throttle characteristics of the labyrinth regulatory valve depend on the structure of the throttle disc, a reasonable design of the throttle disc can effectively improve the conditioning valve performance. A design process for throttle disc path optimization is proposed, based on fluid dynamics theory and numerical simulation method, combined with NSGA-II multi-target optimization algorithm to achieve the three-dimensional optimization design of throttle path. Based on the maximum velocity and flow rate in the throttle path, the path geometry is selected as input parameter, computational fluid mechanics is combined with NSGA-II algorithm, and the optimized path three-dimensional structure is obtained. The optimized design of the valve disc structure effectively reduced the maximum flow rate and improve the flow rate. The study of throttle path optimization design can provide reference for the design of relevant design.
