基于CFD的龙舟训练器关键技术研究

以风阻式龙舟训练器为研究对象，分析划桨过程受力变化特点和相关风阻训练器工作原理。首先对划桨过程中桨叶入水进行受力分析和相关阻力计算，并利用CFD技术验证计算结果，得出计算结果与仿真结果基本相符的结论；然后针对龙舟项目的特点，通过与传统龙舟训练方式的对比，力求水上运动的模拟程度最大化，利用风阻模拟桨叶在水中受力状态，以达到真正模拟划船训练动作和效果的目的。

Research on the Key Technology of Dragon-boat Trainer based on CFD

Taking the dragon-boat trainer with wind resistance as the research object, the characteristics of the force variation during rowing and the working principle of the trainer were analyzed. Firstly,the force analysis of the blade into the water during the rowing process was carried out, and the relevant resistance calculation was carried out. The CFD technology was used to verify the calculation results, Then through the comparison with the traditional dragon boat training mode, strive to maximize the simulation degree of water sports, the use of wind resistance to simulate the blade in the water stress state, in order to achieve the purpose of simulating the rowing training movement and effect.
