摘要
以双调距桨为研究对象,应用CFD方法(FLUENT和ANSYS Workbench软件),分别建立有限体积元模型和有限元模型,将有限体积元模型仿真计算得到的桨叶三维水动力载荷施加在有限元模型的桨叶叶面上,进行双调距桨桨叶的应力及变形的仿真计算与分析,揭示双调距桨的桨叶应力与变形随螺距角、进速系数的变化规律,为调距桨的设计与优化提供理论支持。
Both finite volume element model and the finite element model of twin controllable pitch propeller are established with CFD method including FLUENT and ANSYS Workbench software respectively. The three-dimensional hydrodynamic loads of the propeller blade which are obtained by finite volume element model are applied upon the propeller blade surface of the finite element model,to carry out the simulation of stress and deformation of the propeller blades. The numerical results reveals the variation law of stress and deformation of the controllable pitch propeller blades with pitch angle and advance coefficient,and provides the theoretical support to design and optimization of the controllable pitch propeller.
