“…An excellent agreement is observed, with error reaching 0.6%. In fact, the numerical results show a good correlation of the noted natural frequencies through the same conditions and paramters of gearbox mentioned by Hmida et al [27]. Also the same FRFs curves of the third bearing (y 3 direction) for two methods is shown in Figure 4.…”

“…As a result, the coupling dynamics cannot be neglected when examining dynamic responses. The results moreover displayed that the existence of the connection declined the natural frequencies and the magnitude as proved in [19,27]. In addition, the coupling natural frequency is found to be quite sensitive to coupling stiffness.…”

“…Thus, the global system is divided on two subsystems A and B with two equal halves of the coupling inertia. The aforementioned model is investigated by comparing with the work suggested by Hmida et al [27] and Chaarii [26] as a reference. For instance, Figure 4 depicts the FRF of a subsystem B with flexible coupling in the radial direction of the third bearing (y 3 direction).…”

“…The natural frequencies of the gearbox obtained with the proposed dynamic substructuring method were compared to direct FRF results of Hmida et al [27] which is presented in Table 1. An excellent agreement is observed, with error reaching 0.6%.…”

The aim of the present work is to analyze the sensibility of an elastic coupling on the coupled Frequency Response Functions (FRFs) of transmission mechanical systems. The FRF of a linked system, such as a reducer stage, is determined by a receptance coupling (RC) method. The equilibrium and the compatibility conditions are applied.This method is investigated for different coupling models such as rigid and flexible. The proposed method is validated by a direct computation of the full system showing exact agreement.Afterward, the effect of a rigid and a joined system on the sub-structuring response FRFs is analyzed. The coupling models derived from literature review are discussed to show their effects on FRF. Although the coupling in question is considered to be a flexible interface in the aforementioned system, as revealed in the literature review, it introduces a translational and rotational damping and stiffness. So, the formulation of the RC is different from the standard approach. In order to achieve the aim of the present work, the effects of some important parameters such as translational and rotational coupling, shaft and bearing stiffness on the FRF are discussed. Some sensitivity of the proposed models are observed in relation to the coupling parameters.

“…They studied the interaction between gear mesh and bearings excitation in case of variable speed and load. Hmida et al [18] adopted the model of Chaari et al with the addition of an elastic couple. Instead of the elastic couple, a clutch has been used by Walha et al [19] in a helical gear model.…”
