Electrical Bolt Connection Durability and End of Life Characterization
AVL is the world‘s largest independent company for development, simulation and testing technology of powertrains (hybrid, combustion engines, transmission, electric drive, batteries and software) for passenger cars, trucks and large engines.
We offer a master thesis on the following topic:
Electrical Bolt Connection Durability and End of Life Characterization
Bolts are used in all vehicle battery systems to some extent. The exact effects of thermal and mechanical cycling on battery operation and performance are not fully defined/known. The goal of this thesis is to test various bolting configurations with different underlying materials in conditions commonly experienced during the battery operating lifetime. This information then needs to be transferred into the battery analysis process through FEM Simulations.
Task:
- Detailed literature study on existing pertinent information
- Performing mechanical testing to collect required data
- Validated FEM simulations
- Development of existing/creating new methodology
Field of study:
Mechanical Engineering, Mechanical Engineering and Business Economics
Requirements:
- Understanding of mechanical concepts
- Knowledge of finite element method
- Basic experience with numerical simulations
- Knowledge of Abaqus FEA is desirable
