“…Tang et al used the helical gear of a CRH380A high-speed train as the research object, synthesized Pro/E and ANSYS Workbench, and deeply analyzed its meshing characteristics and performance. The dynamic contact stress state is revealed through modeling and finite element simulation, providing substantial guidance for gear strength calculations [8].…”

Aiming at the deficiencies of the traction helical gear transmission system when the EMU is running at high speed, this paper proposes and designs a kind of arc toothed cylindrical gear adapted to the traction of higher speed EMU. A parametric arc toothed cylindrical gear model was constructed using CREO, and its dynamic contact characteristics and acoustic response characteristics were analyzed under sustained operating conditions using the finite element boundary element method. The design of a tooth profile combined with the radius of the arc toothed line of the comprehensive trimming program put forward a virtual trimming prototype method through MATLAB and CREO reconstruction gear, and trimming before and after the gear transmission simulation experiments occurred for comparison and analysis. This study shows that the traction arc toothed cylindrical gear comprehensive modification method proposed in this study achieves better dynamic performance optimization, effectively reduces the contact stress and radiation noise of the gear transmission, and provides a theoretical basis for the development of a new generation of high-speed EMU stock traction drive systems.

“…The single and double pair gear teeth contact are also considered. Zhaoping Tang and al [6] analyzed meshing characters of high speed train helical gear, studied tractive performance curve of CRH380A, and took the CRH380A train's G301 traction helical gear as an example, gear pair was established by Pro/e and then imported into ANSYS workbench to explore the nonlinear contact condition, mainly studied the dynamic contact stress state of helical gear during three working conditions as start-up, continuous and high speed. Santosh S. Patil [7] made a study on the contact stresses among the helical gear pairs, under static conditions, by using a 3D finite element method.…”

The matting of gears can be considered one of the most complicated faults to diagnose because its vibratory signature is not really known. In addition, the integration of cracks in digital models is not a simple task. On the other hand, the diagnosis of gears can be done in the time domain through statistical method or in the frequency domain through spectral analysis. In this study we made a vibratory analysis on the whole transmission system from raw mill to the Hamma bouzien-constantine cement plant, and then we compared these results with a numerical model. The numerical results found are very close to the experimental one. The experimental study was carried out by the OMNITREND processing software and the numerical simulation by ansys workbench.
