The invention discloses a three-degree-of-freedom flapping mechanism and a simulation method, and belongs to the field of micro flapping-wing aircrafts. A rotating shaft is installed on a fixed rack, flapping rocker arms and rocker arms are fixedly installed at the two ends of the rotating shaft, rotating flapping pieces are rotatably installed on the flapping rocker arms, rotating pieces are rotatably installed on the rocker arms, a steering engine is installed on the fixed rack, a steering engine rocker arm is installed at the output end of the steering engine, and one end, connected with the rocker arm, of the steering engine is rotatably connected with the steering engine rocker arm. The other end of the steering engine connecting rocker arm is rotationally connected with the rotating flapping piece, the two ends of the curve connecting rod are rotationally connected with the flapping wing connecting rod piece and the rotating piece respectively, the flapping wing connecting rod piece is rotationally connected with the rotating flapping piece, the flapping wings are fixedly installed on the flapping wing connecting rod piece, and a flapping rotating gear is installed on the rotating shaft and connected with the motor. The problem of realizing multi-degree-of-freedom flapping action in a limited space of the micro flapping-wing air vehicle is solved, and flapping-wing flapping, twisting and tilting three-degree-of-freedom motion of the micro flapping-wing air vehicle is realized.
