摘要:作为许多动力机械的核心部件的叶轮,其强度及可靠性的问题日渐突出。叶轮工作时,流体力和高速旋转时的离心力为其主要载荷。基于Workbench软件对整体叶轮的内部流场和工作压力分布进行数值模拟;使用ANSYS CFX进行复杂几何形状叶轮的流体动力分析,得到了整体叶轮的流场和工作压力场及流体载荷在叶轮内部产生的等效应力分布图,并耦合了旋转离心载荷等,研究了在高压工况情况下,叶轮的载荷组成和流固耦合下的叶轮强度。

Abstract:As the core component of many power machines, the impeller strength and reliability problems have become increasingly prominent. Fluid force and high-speed rotation of the centrifugal force are main payload in working conditions. We use the Workbench software to simulate the integral impeller flow field and pressure distribution, and using ANSYS CFX to analyses the fluid dynamics of the complex impeller. Through the analysis, impeller flow field and pressure field and fluid loads inside the impeller and equivalent stress distribution were obtained. This paper studies in the case of high-pressure conditions, the composition of impeller load and the impeller strength under the fluid-structure interaction.
Key words:integral impeller;Workbench;fluid pressure;fluid-structure interaction
