Abstract： To ensure that a certain wind tunnel can simulate the effect of gust and ensure the reliability and safety of structural design and selection，its motion simulation is carried out on the wing shaped blade drive structure of the rocker arm cam，the changes of motor output energy and torque with time are calculated，and the loads on key transmisson positions of the structure are predicted.The simulation results show that： the motion trajectory of the gust generator is close to a sine curve，the motor parameter selection is reasonable，the structure is safe and reliable，and the gust simulation effect meets the test requirements.

Key words： gust generator；mechanism motion trajectory；motor selection； finite element
