摘要
针对国内无人帆船稀缺的问题,本文设计一款简单的手动调节副帆角度的无人帆船,采用导轨和滑轨的硬摩擦配合,实现了帆的相对角度调节。为检测无人帆船的行进效果,将主帆和副帆模型简化后,导入有限元分析软件ANSYS-Workbench中,在Fluent模块下进行空气动力仿真分析,并通过设置升力系数和阻力系数,使迭代步数运算至3000步,得到收敛的运算结果及帆的三维流线云图和压力云图。仿真结果表明,空气涡流产生于主帆与副帆环抱夹角内,最大压力集中在帆的外侧,约为0.047 MPa,因此空气对帆船产生向前的推力,达到无驱动力下的行进效果,符合实际工况要求。该研究对国内无人帆船的发展具有参考价值。
In view of the scarcity of unmanned sailing ships in China,a simple unmanned sailing ship was designed to adjust the angle of the auxiliary sail manually.The relative angle adjustment of the sail was realized by the combination of the hard friction between the guide rail and the slide rail.In order to detect the moving effect of unmanned sailing ship,the model of the main sail and the auxiliary sail was simplified into the finite element analysis software ANSYS-Workbench,and the aerodynamic simulation analysis was carried out under the fluent module.By setting the lift coefficient and drag coefficient,the iteration steps were calculated to 3000 steps,and the convergent operation results were obtained.Finally,the three-dimensional flow chart of the sail and the pressure cloud were obtained.The result shows that the air swirl is produced in the angle between the main sails and the auxiliary sails.The maximum pressure is concentrated on the outer side of the sails,about 0.047 MPa.The air thus gives the sailboat a forward thrust to achieve the driving effect without driving force.
