| Abstract: | With a view to overcome the resonance in the planetary gears transmission,the dynamic characteristics of the planetary gears were investigated with dynamic method.A torsion vibration mechanical model was established based on Lagrange method,and the sensitivity expressions of the design parameters was deduced.In addition,dynamic modification method was proposed based on sensitivity analysis.The results can be referenced theoretically in the planetary gears optimization. |
