摘要
This paper presents a global optimization method focused on planetary gear vibration reduction by means of tip relief profile modifications.A nonlinear dynamic model is uspd to study the vibration behavior.In order to investig ate the optimal radius and amplitude,Brute Force method optimization is used.One approach in optimization is straightforward and requires considerable computation power:brute force methods try to calculate all possible solutions and decide afterwards which one is the best.Results show the influence of optimal profile on planetary gear vibrations.
