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.
