Vibration Analysis And Visualization Application Research Of Planetary Gear Transmission

In this thesis, the author carry through dynamics analysis and research of the 2K-H planetary gear and carry out a great deal of numerical calculation based on Matlab software.Firstly, the authour builds up the concentrated parameter vibration model of the 2K-H planetary gear with floating carrier and got the vibration differential equations by applying the relative kinematics dynamics theory. It is showed by the example that the concentrated parameter vibration model are feasible based on that the gear are regarded as spring and the object of gear as mass.Secondly, on the base of FEM, mesh stiffness of straight tooth cylindrical gear is calculated, and curve of stiffness is find.The method of calculation and the programme may be used in practice of project.Thirdly, on the basis of relative kinematics dynamics, The vibration responses of multi-freedom system is obtained by the addition method of damp system response.The programme of calculation is workout, and the result of calculation is analysed.All these is the base of the analysis of dynamic performance of the planetary gear transmission .At last, a post-processing method, including color mapping and animation technique and so on, is used in the result of vibration analysis of 2K-H planetary gear. The results of the application are very favorable.
