The self designed flappingwing vehicle with two degrees of freedom (2DoF) is taken as a research object. The curve of flapping angle and torsion angle of the vehicle were fitted and written it to the User Define Function (UDF) program to couple with Fluent fluid solver. The average lift coefficient, thrust coefficient and energy coefficient during movement were analyzed, then, which results compared with flappingwing vehicle with a single degree of freedom (1DoF). The results show that the average lift coefficient of the flappingwing with 2DoF is 188 times higher than that of the flappingwing with 1DoF, and the average thrust coefficient is increased by 175 times, at the same time, average energy coefficient of the flappingwing with 2DoF reduced by 275%, which has better lift efficiency and propulsion efficiency. It shows that the designed flappingwing vehicle with 2DoF can generate enough lift for flying, and has better aerodynamic performance than the traditional flappingwing vehicle with 1DoF.
