应用Solidworks软件对某型船用流量平衡阀流道结构进行优化设计，首先将几何模型导入Fluent软件中进行压力场和速度场仿真分析计算，获取改进后的阀体三维模型。进一步利用Ansys软件和声学分析软件LMS预测了流量平衡阀在不同工作压差和阀芯位移下流道的噪声和振动特性曲线，分析结果表明：阀体噪声和振动随着工作压差和阀芯位移的增加而变大。本文对于冷水系统各类阀件减振降噪设计具有一定的指导意义。
This paper establishes an optimization design of the channel structure for some marine flow balancing valve with Solidworks software. Firstly valve geometrical model has been imported in the Fluent CFD software to simulate the distribution of pressure and velocity field，which can obtain the improved 3D valve model. Moreover the noise and vibration curve of the valve channel under different pressure difference and valve core displacement have been predicted with ANSYS and LMS software. The results show that the valve noise and vibration become larger with the increase of above factors. This paper provides the reference for the design vibration and noise reduction in water system valves.
