1. Dynamic Response of a Car Window-Lift Motor Assembly

In collaboration with Dipl.-Ing. Holger Dietzhausen (Robert BOSCH GmbH) and Prof. Kai Willner (Institute A of Mechanics, University of Stuttgart)

Conventional ways of simulating the dynamic behaviour of assemblies and joints used springs at the interfaces. The stiffness of each of the springs was found using a Monte Carlo optimization method to validate the experimental and simulated Eigen modes of the structure. In this work a new simulation technique was developed to address this problem, a soft contact formulation was proposed to validate the experimental and simulated Eigen modes of the structure. The results showed a good agreement between experimental and simulated response of the structure. Computational efficiency was improved by 20%.

2. Diffusion Process (Carburization) Simulation Code

In collaboration with Dr. Juergen Gegner (SKF GmbH) and Prof. Dr.-Ing. Andreas Oechsner (Institute of Applied Mechanics, University of Erlangen)

Most of the finite element software used to solve the transient diffusion problems by taking into account 1D FICK's law in Cartesian coordinates, which is suitable for larger radii cylindrical and spherical components. But for the cases of small radii i.e. small components (small spherical ball used in ball bearings) this approximation is not sufficient and results in larger differences if compared with the analytical solution. A software code hads been developed based on the analytical solution for one dimensional diffusion problems. Results were then compared with implemented cylindrical and spherical coordinate diffusion equation in finite element software MSC-MARC. At the end, a software code to solve the complex problems was developed using finite difference scheme.
