Analysis of planetary gear transmission in non-stationary operations

Fakher CHAARI, Mohamed Slim ABBES, Fernando Viadero RUEDA, Alfonso Fernandez del RINCON, Mohamed HADDAR

Frontiers of Mechanical Engineering 2013, Volume 8, Issue 1,   Pages 88-94 doi: 10.1007/s11465-013-0361-8

Abstract:

Planetary gearboxes operate usually in non-stationary conditions generated mainly by variable loads applied to these transmissions. In order to understand the dynamic behavior of planetary gearboxes in such conditions, a mathematic model is developed including driving unit, transmission and load. The variability of load induces a variable speed of the transmission which is taken into account when characterizing the main dynamic parameter of the transmission which is the mesh stiffness function. This function is not periodic following the variability of the transmission speed. The computation of the dynamic response shows an intimate relation between the vibration amplitude level and the load value. As the load increase the vibration level increase. A combined amplitude and frequency modulation is observed which is well characterized using Short Time Fourier transform more suited than the spectral analysis.

Wang Yuqing,Liang Jian

Strategic Study of CAE 2001, Volume 3, Issue 12,   Pages 68-70

Abstract:

the calculation of contacted points´ principal curvature is the key to determine contacted area. Traditionally, the method of determining principal curvature is to make use of the theory of mesh and coordinate transform. However, this method is complex. In this paper, based on the feature of curve surface, moving frame and co-differential are employed to give a sententious, effective algorithm of principal curvature. Then, according to the formulation of contacted area, an application example is given. This algorithm can be used for calculation of principal curvature in all kinds of curve surfaces.
