Flood Proof Design of a Train Converter

Sammanfattning: The objective of this thesis is to enhance the TC1500 LAB converter, which is anelectrical train converter to be waterproof up to a height of 650 [mm] from raillevel, addressing a pressing need in railway systems. The critical components ofthe converter have been identified for consideration. Using Freddy Olsson'smethod and the concept screening method, various designs were generated, withone alternative design chosen for each critical part identified. The result of thisproject includes innovative designs that fulfill both the company's requirementsand the functional needs identified during the project. Each design's resilienceunder various loads and environmental conditions was assessed using simulationsconducted in SimSolid, all of which successfully met the defined requirements.An actual experiment was done to validate the simulation model used in SimSolid.This work not only advances our understanding of converter design andwaterproofing, but also provides practical solutions for enhancing the durability ofrailway systems. The insights from this thesis serve as valuable resources forfuture research and the improvement of similar components in other railwaysystems.
