AFRY  is among engineers rated as one of the most popular employers in Sweden.

We are now looking for one or two master students for this master thesis:

Background
When designing a wheel suspension for a vehicle, the distribution of loads from the road contact is dimensioning for material selection and design concepts. Therefore it´s important to early in a vehicle project have some realistic initial loads to start from. MBD simulations normally starts with focus on K&C, while the FE engineer wants to focus on loads.  

Objective
The objective of this thesis project is to develop an FE based method for suspension load calculation in early phases and correlate it to a more traditional MBD model based method. Evaluate the influence of bushing compliance and sensitivity of minor geometry changes.

The result should be a validated FE method and user guideline, useful for future vehicle project concept phases.

Method

• From an existing suspension geometry, build up one FE model and one MBD model.
• Define critical loadcases and apply loads in both models.
• Perform sensitivity studies, varying parameters
• Draw conclusions from comparison of the models

Deliverables
A report containing:

• Guidelines and method description for the FE based method
• Limitations of the FE based method

Master Programs: Applied Mechanics, Mobility Engineering.
The project is suitable for 2 students and will be performed in Trollhättan.  

In the department CAE & Safety, in Trollhättan, you will be part of the team that performs strength, durability and NVH analysis to develop the performance and attributes of vehicles and systems of the future. Our customers are both local and international. 

You are welcome to submit your application already today, with a personal letter and CV. We will handle the applications continuously. Candidates situated in Sweden with interest in Trollhättan will be prioritized. 

If you have questions about the thesis project, you are welcome to contact CAE section manager Annika Aleryd, [email protected] or CAE Team Leader Robin Kristiansson, [email protected]
