摘要
为实现某企业阀门系统口径550mm电动闸阀结构轻质化要求,研究阀体内部流场分布状况,运用有限元法对阀体结构进行瞬态动力学分析与形状优化。建立闸阀参数化模型,采用有限元分析软件对优化前阀体强度进行数值模拟,并基于DOE对闸阀壁厚进行目标优化设计,对优化后的阀体进行流固耦合分析,得到阀体受到的最大等效应力为103MPa。结果表明,改进后的阀体强度能够满足实际工况要求,与原设计相比,产品重量减轻26%,轻量化效果显著。
In order to realize the demand for lightweight structure of 550mm electric gate valve of a valve system in an enterprise,the distribution of flow field inside the valve body was studied,and the transient dynamics analysis and shape optimization of the valve body structure were carried out by using the finite element method.The parametric model of gate valve was established.The strength of valve body before optimization was numerically simulated by finite element analysis software,and the gate valve wall thickness was optimized based on DOE.The optimized valve body was analyzed by fluid-solid coupling,and the maximum stress of valve body was 103MPa.The result shows that the strength of the improved valve body can meet the requirements of the actual working condition.
