30 hp – Control strategy for conditioning Gearbox oil in Testbed

A Diploma work at Scania is an excellent way of building relations with a potential future employer. Many of our co-workers today started their Scania careers with thesis work.

Background

Scania Test Rig Development (NLR) and subgroup Testing Systems (NLRI) are responsible for developing technical solutions for component testing at Scania R&D. A testing system may refer to anything from a small setup for testing mechanical durability of a piston to a large wind tunnel testbed testing entire trucks and buses.

In our e-mobility Testbeds we run highly dynamical tests on our e-gearboxes, therefore we need to find the optimal control strategy for conditioning the temperature of the oil in the existing equipment.

Assignment

Many testbeds for e-mobility use an in-house designed oil conditioning unit with PLC code written in Beckhoff TwinCAT™. The goal of the project is to evaluate and improve the existing control strategy in this oil conditioning unit by:

• Analysing the strengths and weaknesses of the current control philosophy
• Evaluate the control algorithms in the control Toolbox of TwinCAT™
• Implement a new and improved control algorithm
• Test the new implementation both in our simulator and on the existing equipment to evaluate the result

Suitable education could be a master of science in Mechatronic or Engineering Physics with courses in control theory and programming
