PROJECT FILLED - Planetary gear analysis

PROJECT FILLED

Functional area: Mechanics Department, R&D, Atlas Copco Industrial Technique AB

Target

Make a complete model of a planetary gear with respect of bearings, shaft deflections and tooth contacts. This should be made in our gear calculation program KISSsoft (+Code Aster open source FEM solver) and Creo Simulate. Perhaps also on additional systems like Romax and Ansys if needed. We would like to investigate how simple the model can be to be good enough and when it is needed to do more extensive calculations.
The task can of course be modified after agreement.

Background

We develop many different planetary gear trains on our tools. The purpose for the gear train varies from product to product. It can be extremely light, long life, small, robust etc. We would like to get more knowledge in design criteria of these gears trains.

Mission

The main goal is to make a base understanding on how all deflections is impacting a planetary gear train and to find a reasonably easy way to calculate this.

Relevant educational background

Level of thesis project

Qualification

We believe that this master thesis is suitable for master students in mechanics with an interest in contact mechanics, FEM, gears and bearings.

Swedish is not a requirement, but will be considered a plus.

Additional information

Our office is located in Sickla, Stockholm.

As this is a project position for studies and not an employment, it does not qualify for seeking a work permit. We can therefore only accept applications from students who are either attending Swedish universities (i.e. already have a student visa) or, if they are attending universities abroad, are EU-citizens.
