The gear foundation is commonly assumed to be a rigid body in analyzing the dynamic
characteristics of the gear system. This modeling approach may not be appropriate for …

In this paper, a review of the evolution of the study of cylindrical gear dynamics is presented.
After a brief historical introduction to the field, the first attempts to describe the complex …

This paper proposes a new effective mesh stiffness calculation method for spur and helical
gear pairs, which is explicitly formulated by an original FE-analytical slice model for tooth …

In this paper the transmission error and the strain field are analysed for two gear pairs, with
different lightweight designs, reflecting the common industrial practice. The methodology …

Considering the flexibility of gear foundations and rotational effects, a geared rotor dynamic
model for thin-rimmed helical gears is established. The deformable shafts and gear …

Geometric eccentricity error is unavoidable in gear systems, resulting that the center of mass
and center of rotation do not coincide with each other. The gear center distance and …

Bevel gears, a crucial part of aircraft transmission systems, are more susceptible to wheel
body vibration issues as lightweight requirements rise. In the past, the gear wheel body was …

In this paper the effect of the of individual tooth inertia on spur gear dynamics is investigated.
A lumped element model is developed, in which tooth and gear inertial properties are …

This paper proposes a refined methodology to simulate the non-linear dynamic response of
spur gears. The multibody model is based on a penalty contact formulation and considers …

With the growing demand for lightweight gear transmission systems, composite materials
have emerged as a promising solution due to their high specific properties. However, the …
