Req ID:469527 

At Alstom, we understand transport networks and what moves people. From high-speed trains, metros, monorails, and trams, to turnkey systems, services, infrastructure, signalling and digital mobility, we offer our diverse customers the broadest portfolio in the industry. Every day, more than 80 000 colleagues lead the way to greener and smarter mobility worldwide, connecting cities as we reduce carbon and replace cars.

We are looking for a Master thesis student to join our team in Västerås

Topic proposed: Characterization of inductors for sound prediction on trains

Duration: 20 weeks, on-site

Background 
​Alstom has identified a need to improve the sound environment on trains by predicting the sound from inductors and transformers in converters. It has proven difficult to obtain useful results through the simulation of electromagnetism - structure and airborne sound. Therefore, a thesis is proposed to characterize inductors and find significant common denominators that affect sound radiation.​  

 
Problem description and goals 
The goal of the thesis is to develop a method for predicting sound from inductors on trains. To achieve this, a number of inductors will be measured and analyzed through modal analysis and sound measurement. The results will be used to identify factors that affect the sound and propose a method for sound prediction. 

The scope of the project can be adapted to suit one or two thesis students.
