Study On Transient Meshing Performance Of The Gear Of Wind-power

Gear transmission system is one of the key components influencing various performances of wind-power. The transient performance of the gear transmission system of wind-power was studied in this paper. Based on the study of the method of applying the boundary condition and the load and defining the contact between the gears etc key problems, the full three-dimension FEA model of the gear mesh system was built up, and then the model was calculated on the computer to simulate the meshing between the gears. In the calculated result, the displacement, velocity, acceleration information of all of the nodes and the stress and strain information of all of the elements can be obtained.In this paper, the calculated result was analyzed in details and the stress distribution and the vibrating condition and the change of them everywhere on the gear were obtained during the meshing course. The transient stress distribution along the breadth of the tooth and depth of tooth and the influence of profile modification were further studied.
