Finite element analysis of cylindrical gear with mechanical event simulation

摘要

In this paper, we present the finite element analysis of a cylindrical gear using the Autodesk Simulation Mechanical software, with mechanical event simulation (MES). MES combines the kinematic, rigid, and flexible-body dynamics with the nonlinear stress analysis. Therefore, MES can be used to simultaneously analyse mechanical events involving large deformations, nonlinear material properties, kinematic motion and the forces caused by this motion for predicting the resulting stresses. It is essential that MES can be used to define the surface contact between the teeth in contact at a given time, the analysis parameters by time steps, respectively the kinematic and kinetostatic parameters, variables defined by certain curves. We use the analysis to find the stress distribution, nodal displacements, etc. in the contact area of the two gear wheels, at different time steps of the kinematic cycle.
