Analysis of dynamic excitation behavior of a two-stage spur gearbox

In times of engine downsizing and lightweight design, the dynamic and acoustic behavior of multi-stage gearboxes is becoming increasingly important. One parameter is the manufacturing quality of the gears which can be expressed by DIN standard and is influenced among other things by the production process. The presented objective is the analyzation of the dynamic behavior with focusing dynamic interactions of two-stage gearboxes. To achieve this goal, gears with different micro geometries and the interactions between the meshes are investigated mathematically. Therefore, a dynamic multi body simulation model is presented in which gear meshes will be described as force coupling elements. (C) 2017 The Authors. Published by Elsevier B.V.
