| Abstract: | The dynamic analysis was performed and the calculation analysis model was built by using the contact finite element method for spline joint structure of rotor system.The structural parameters of the locating surface distance, the locating surface nip and the contact area etc. were investigated and the influence law of the load on the coupling stiffness and the contact state of the spline joint structure were also investigated. The dynamic design methods of the spline joint structure were presented based on the investigation which included the design methods of the coupling stiffness and the contact state. The calculation and analysis of the spline joint structure for an aeroengine turbine rotor were conducted. The feasibility of the dynamic design method of spline joint structure was verified. |
