“…Therefore, its value should be selected very carefully. Fernandez-del-Rincon et al 39 presented a mathematical model for a geared rotor-bearing system. The authors investigated the system considering the clearance, variable compliance of bearing, and the meshing forces and meshing stiffness of the gears.…”

Rolling element bearings are one of the most precarious components and play an important role in the effective operation of rotating machinery. Bearings are one of the foremost sources of nonlinearity in rotating machineries which significantly affect the behavior of the system. The main sources of nonlinearity are radial internal clearance, unbalanced force, bearing preload, stiffness, damping, number of rolling element, and so on. Surface defects such as localized and distributed defects are also accountable for the nonlinear behavior of the system. A large number of studies and methodologies have been proposed in the last two decades to understand the nonlinear dynamic behavior of rolling element bearings considering various bearing parameters and surface defects. In this work, the authors have presented a review of different theoretical models and experimental works proposed for the analysis of the nonlinear behavior of rotating systems. This review article first quotes various techniques which have been explored for the nonlinearity analysis in rolling contact elements such as rotor-bearing system and gears. Some of the important gaps are highlighted in this work which can be considered for future studies.

“…MATLAB program was adopted to systematically analyze the vibration displacement and velocity response of the gears (Wu et al, 2017). Fernandez-Del-Rincon et al (2017) presented a model that could simultaneously consider the internal excitations due to variable meshing stiffness (including the coupling among successive tooth pairs in contact, non-linearity linked with the contacts between surfaces and dissipative effects). The model could also simulate gear dynamics in a realistic torque dependent scenario.…”

“…The proposed model combined a hybrid formulation for calculation of meshing forces with a non-linear variable compliance approach for bearings. The meshing forces were obtained by means of a double approach which combined numerical and analytical aspects (Fernandez-Del-Rincon et al, 2017). Bouslema et al (2017) aimed at the application of a substructure methodology, based on the Frequency Response Function (FRF) simulation technique, to analyze the vibration of a stage reducer connected by a rigid coupling to a planetary gear system.…”

Abstract. A novel transmission with multistage face gears as the core component achieves variable speeds via differential gear shifting. Single/multistage coupled vibration models have been established in this study to derive the coupled vibration equation in order to accurately solve the load distribution between the meshing teeth and the vibration shock between the shifting stages in the transmission process, improve the transmission smoothness of the face gears during the shifting processing, suppress the resonance of face gears meshing, reduce the noise, and optimize the power transmission performance. The characterization relationships of the key parameters such as equivalent mass, rotational inertia, equivalent mesh stiffness, support stiffness, and meshing damping coefficient to dynamic characteristics were investigated. The linear and nonlinear dynamic characteristics of coupled vibration differential equations were solved. The influence rules of factors such as integrated transmission error, dynamic load, tooth surface friction, loading speed, and load on the transmission system were analyzed. The results of the study provide a theoretical basis for the expansion of field of application of transmission devices.

“…Shao Yimin [30] studied the change of mesh stiffness at the time of the end of peeling boundaries. Fernando [31,32] presented a developed model to simulate gear transmission dynamics. The developed model is capable of considering simultaneously the internal excitations due to the variable meshing stiffness and other excitations.…”

This paper investigates the effect of a gear tooth peeling on meshing stiffness of involute gears. The tooth of the gear wheel is symmetric about the axis, and its symmetry will change after the gear spalling, and its meshing stiffness will also change during the meshing process. On this basis, an analytical model was developed, and based on the energy method a meshing stiffness algorithm for the complete meshing process of single gear teeth with peeling gears was proposed. According to the influence of the change of meshing point relative to the peeling position on the meshing stiffness, this algorithm calculates its stiffness separately. The influence of the peeling sizes on mesh stiffness is studied by simulation analysis. As a very important parameter, the study of gear mesh stiffness is of great significance to the monitoring of working conditions and the prevention of sudden failure of the gear box system.
