Master Thesis: Abaqus Based Modelling of Ball Bearings

Job description

Transport is at the core of modern society. Imagine using your expertise to shape sustainable transport and infrastructure solutions for the future? If you seek to make a difference on a global scale, working with next-gen technologies and the sharpest collaborative teams, then we could be a perfect match. 

Position Description

At the Transmission Simulation & System Design team FE-analyses of housings and rotating parts of gearboxes and electrical drivelines for heavy trucks are a main staple. These components are usually connected with bearings that enable rotation. To achieve accurate force transfer and thus stress distribution close to a bearing seat it is necessary to have bearing models that are good enough. We have developed such models in Abaqus for over ten years. The current situation is that there are models of varying degree of maturity for ball, needle, and tapered and cylindrical roller bearings.

Such models must, depending on the requirements of the analyses attempted, be able to correctly describe either the average or local behavior of the bearings and thus provide FE-results of the desired detail level close to the bearings.

Description of thesis work

· 
Investigate different methods of modelling deep groove ball bearings with Abaqus FE-models and identify the methods that work satisfactory for different load cases, e.g. pure radial load, radial load combined with axial load, and different misalignment.

· 
Analyze which factors that affect the behavior and try to generalize the modelling parameters for bearings of different sizes and sections.

· 
Expand the results to include angular contact ball bearings and 4-point contact ball bearings.

·  (if time allows) Implement the identified method in the existing tool.

The current bearing models are created with a Matlab GUI. The work would include creating bearing models with the existing GUI as well as modifying the relevant parts of the code for the new implementations. The results of these models should be compared with results from dedicated commercial shaft and bearing analysis tool as well as some cases of detailed FEA with solid modelling of the rolling elements. Performing these detailed FEA:s is not part of the thesis work.

Qualifications & Key Attributes

·  Master student in Engineering Physics, Mathematics or Applied Mechanics
·  Positive attitude, willing to learn, disciplined, good communication skills, humble, result oriented
·  Experiences in Abaqus and Matlab programming are a merit 

Duration

The thesis project will start in January 2025 and continue 20 weeks. The diploma work gives 30 points (ECTS) per student.
