Thesis work at R&D Handheld ICE – Power Systems – Base Engine

Last date to apply:

We are now looking for master students in mechanical engineering that are interested in doing their thesis project at our2-stroke engine development department.

We are one of the worlds oldest startups and this is just the beginning. At Husqvarna Group we develop worldclass products and technologies for forest park and green space care. Within our Global Handheld R&D division we are driving the development of the next generation of powertrains where the twostroke engine plays a central role for our most demanding users both today and in the future.

The Base Engine team is responsible for the cylinder piston crankshaft and bearings including interfaces with other subsystems.

Background:

Threaded holes with wedge ramp features such as Spiralock and Safe-Lock to improve the performance of screw joints have been on the market for some time. However the performance depends on factors such as temperature vibration and material. Data from scientific testing under application-like conditions would be required to properly map advantages and disadvantages of wedge ramp threads in our products.

Objects:

Develop and execute a test plan for wedge ramp threads compared to standard threads in cast aluminium and magnesium aligned with loads temperatures and vibrations that are present in our applications. Provide analysis on outcome and best recommendation on if/how to apply for given joints.

Proper area of education

Masters in mechanical engineering / physics / or similar & product development.

The thesis will include work such as

• Analytical and theoretical studies of screw joints with wedge ramp threads compared to standard threads
• Simulations (e.g. FEM) to evaluate load cases temperature effects and contact conditions
• Experimental testing based on a structured test plan including Design of Experiments (DOE) under applicationrelevant loads temperatures and vibration levels
• Analysis and synthesis of results leading to clear recommendations on if and how wedge ramp threads should be applied for specific joints

How to apply
Please send in your application with CV and cover letter no later thanMay 15th. Due to GDPR we do not accept applications by email.

Start date of the thesis project is in Q3/Q4 of 2026.
