Modal Analysis of Speed-reducer Bevel Gear of Aerial Passenger Device for Coal Mine

The basic theory of modal analysis is introduced. Solid model of speed reducer bevel gear of aerial passenger device for coal mine is established through 3D design software UGNX. The modal analysis is carried out by ANSYS Workbench. The first six natural frequency and modes of the bevel gear are obtained. The results of modal analysis provide reference for the design and improvement of the gear.
