Topic proposed: Multi-physics optimization of an induction motor for Railway vehicles  

Duration: 20 weeks, on-site

Background
The demands on traction motors for railway vehicles are increasingly rigorous. Key requirements include compact design, high energy efficiency, and minimal acoustic noise. Currently, design optimization employs advanced tools that operate separately across distinct models for structural mechanics, thermal dynamics, and electromagnetic simulations. However, new user-friendly tools now enable optimization within a multi-physics environment, allowing for integrated analysis.                              
 

Problem description and goals

The objective of this thesis project is to explore the application of multi-physics simulations using FluxMotor and the Altair suite to enhance the design of an induction motor for railway applications. The focus will be on optimizing the combined models, initially concentrating on electromagnetic and structural mechanics, with the potential to incorporate thermal aspects if time permits. The project will be structured as follows:

1. Conduct a literature review on multi-physics optimization for induction motors.
2. Complete necessary tutorials to gain proficiency with the simulation tools.
3. Implement the motor model within the multi-physics environment, focusing on electromagnetic and structural parameters.
4. Validate the model against existing calculations from alternative tools or physical measurements.
5. Optimize the motor design based on various criteria.
6. Investigate the integration of thermal simulations, if time permits.
7. Compile a comprehensive report detailing findings and methodologies.
