Dynamic modeling of defective gears

Abstract

The use of geared transmissions has a long history and a rich experience, which has allowed the development of an intense research activity that has led to modern design methods, mostly standardized and execution technologies that have become traditional. As the fundamental sciences have provided more and more in-depth and refined knowledge, namely performance algorithms of optimal synthesis, the design in the field of gear transmissions has evolved by integrating in the calculation methods a growing number of elements. of influence (materials, geometry, dimensional and shape deviations, heat treatments, kinematic, energetic, dynamic factors, etc.). Automated modeling and simulation currently allow the prediction of behavior - from all points of view of a transmission - during operation.

“…Furthermore, the analysis of geometric characteristics is essential in traditional calculation of mesh stiffness, 10,11 especially in different pitting shapes. [12][13][14] Several studies have examined the analytical model of dynamic response of spur gear with pitting. Yang 15 proposed a new dynamic model to simulate the vibration behaviors of a spur gear transmission with pitting and spalling defects, which considered the effect of gearbox and the experimental validation was performed.…”
