MODAL DYNAMIC ANALYSIS FOR THE SHAFTS OF A GEARBOX

Abstract

The main goal of this paper is to determinate the deformations of the shafts of a gearbox. A CAD model of a gearbox is designed in SolidWorks. The dynamic simulation of the gearbox is performed with ADAMS multibody software. In the first step of the simulation the parts are considered as rigid ones. The second step of the simulation proposes to consider the elasticity of the parts, especially of the gearbox shafts. For that, the shafts are meshed with tetrahedral finite elements in order to be considered as deformable solids. The results of the simulation are the shafts vibration modes and the deformations of the mass centers that are discussed in the paper.
