Thesis work: 30 hp - Modelling of a hot shift clutch unit

Introduction
A large portion of the trucks on our roads are more than just a tool for transporting goods, as many are equipped with specialized bodywork that also allows them to function as mobile machinery. The crane on a timber truck, the compactor on a refuse collector or the vacuum pump on a sewage truck are all parts of such body works. This equipment is usually powered by a power take off (PTO) that transmits the vehicle engine power to the bodywork.

Background 
Our group at Traton is responsible for developing PTOs for both conventional and e-mobility powertrains. To keep up with market needs and achieve our vision of being the preferred choice for PTOs, we are constantly exploring ways to improve and expand our PTO portfolio.

A multi-plate clutch in the PTO engagement system, hot shift, increase PTO and vehicle functionality in certain applications.    

Objective

This master's thesis aims to develop a scalable model of a multi-plate clutch system in Matlab-Simulink, capable of handling numerous input design parameters. The model will be validated using physical test data and will serve as a design support tool for future development

Job description

The thesis worker will be based at Traton R&D in Södertälje with the possibility of remote work when feasible. The student will gain first-hand experience working at a leading commercial vehicle R&D. The thesis work will include:

• Literature study on multi-plate clutch and relevant physics
• Plan and perform relevant calculations and analysis
• Development of a scalable Matlab-Simulink model
• Validate the model through test data
• Collaborate with engineers at Traton to contribute to innovative product development

Education/program/focus
