After studying mechanical engineering at Technical University of Munich, Dr. Georg Hammerl did his PhD in the field of computational mechanics. He joined FVA GmbH in 2017 to further develop the FVA-Workbench. He is an expert in finding smart solutions for complex problems, so the user can safely reach the goal with simple workflows.
This study presents a simulation method for considering complex wheel bodies in an analytical tooth contact model. The wheel body is considered using reduced FE stiffness. Reduction points are defined over the width and linked with the analytical gear.
For cylindrical wheel bodies, comparative calculations show fewer deviations from the expected results with the new method. This is due to the additional degrees of freedom in the FEM model. In the calculation with cylindrical wheel bodies, bending due to axial force in tooth contact could also be verified in addition to the deformation in tooth contact and the influence of the shaft-bearing system.
