A gear tooth profile optimization study is performed with the target being defined as the maximization of tooth bending fatigue life for a selected operational range, where the operating torque and speed ranges are defined along with their corresponding durations. For this purpose, a nonlinear lumped gear dynamics model is combined with the S/N curve of the gear material in order to estimate tooth bending fatigue life of the spur gear pair. The differences between the predicted lives of the optimally modified and non-modified gear pairs are presented based on example spur gear pairs. The proposed tooth bending fatigue life estimation is compared with the standard AGMA procedure.

Ideal tooth profile modifications for improving nonlinear dynamic response of planetary gear trains Ozturk, Veysel Yalin; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (2021-05-01) The ultimate goal in this study is to investigate the effects of tooth profile modifications (TPMs) on PGTs by performing parametric studies. For this purpose, firstly a nonlinear planetary gear dynamics model with time-varying stiffness is introduced. A time-varying stiffness function is included into the analysis by using loaded static transmission error (LSTE) for sun-planet and ring-planet gear meshes. In this analysis the computationally calculated values of LSTE are used; however, if an experimentally...
Vibration Fatigue Analysis of a Cantilever Beam Using Different Fatigue Theories Eldoğan, Yusuf; Ciğeroğlu, Ender (2014-02-11) In this study, vibration fatigue analysis of a cantilever beam is performed using an in-house numerical code. Finite element model (FEM) of the cantilever beam verified by tests is used for the analysis. Several vibration fatigue theories are used to obtain fatigue life of the cantilever beam for white noise random input and the results obtained are compared with each other. Fatigue life calculations are repeated for different damping ratios and the effect of damping ratio is studied. Moreover, using strain...
Dynamic modelling and analysis of split-torque face-gear systems Aydoğan, Mustafa Özgür; Özgüven, Hasan Nevzat; Sarıbay, Zihni B.; Department of Mechanical Engineering (2022-8-29) In this study it is aimed to develop a dynamic model for a face-gear drive system that accounts for all important physical parameters related to the operation to achieve an optimized split-torque face-gear based transmission system. With this new model, nonlinear dynamic response of a face-gear drive system is sought and dynamic stability and limit states of this structure are investigated. The main motivation for the current study is the recent development and utilization of face-gear drive...
Nonlinear Dynamic Analysis of a Spiral Bevel Geared System Yavuz, Siar Deniz; Saribay, Zihni Burcay; Ciğeroğlu, Ender (2017-02-02) A nonlinear dynamic model of a spiral bevel gear train mounted on flexible shafts and bearings is proposed in this study. The finite element model of shafts is combined with a three-dimensional discrete mesh model of a spiral bevel gear pair. Bearing flexibilities are as well included in the model. Gear backlash is incorporated into the model in the form of clearance-type displacement functions and clearance nonlinearity and stiffness fluctuations of the bearings are neglected. A time-invariant mesh stiffne...
