摘　　要：使用ANSYS Workbench平台中ACP模块对铜桨和碳纤维桨进行了建模和单/双向流固耦合对比研究。双向流固耦合计算考虑了流体和固体的相互影响,使铜桨和碳纤维桨的敞水性能比单向流固耦合计算值更接近于试验值。碳纤维桨的变形和应力在各种工况下均比铜桨大,二者的双向流固耦合变形和应力均比单向流固耦合时小,且碳纤维桨的减小量更多,说明碳纤维桨的弹性使其更易受水动力载荷的影响,流固耦合现象更明显。In order to develop an ACP module on the ANSYS Workbench platform to calculate composite propellers′fluid-structure coupling performances,a comparative study and modeling of one-way and two-way coupling of copper and carbon fiber propeller are conducted.Since the interrelationship of fluid and structure is taken into account in the calculation of two-way coupling,the open water performance of the propeller is closer to the experimental results compared to the one-way coupling calculation.The deformation and von-mises of carbon fiber propeller are bigger than those of copper propeller under various conditions.The deformation and von-mises of two propellers with two-way coupling calculation are smaller than those with one-way coupling calculation,while the decrease of carbon fiber propeller is larger than that of copper propeller.The results show that the carbon fiber propeller′s flexibility makes it more vulnerable to the hydrodynamic force and its fluid-structure performance is more prominent.
