Beschreibung

Topic:

Joints in multibody simulations determine with which degrees of free bodies are able to move relative to each other. However, joints in real systems also have other complex effects on system dynamics. Phenomena such as stick-slip, contact loss and bearing elasticity are present in many real-work applications but rarely accurately modelled. Including these effects based on real-world measurements is one step towards closing the gap between digitals twins and their physical counterparts. This thesis  will apply the data driven modelling approach SINDy to model a rotational and translational joint in a crank-shaft mechanism. Measurements will be conducted on a testbench in the lab and then processed using Matlab. The goal of this study is the determine what combination of sensors is best suited to fully capture the joint behaviour. 

As with all my theses, the proposed topic is just a starting point. It is flexible and can be adjusted to what interests you and what direction the research leads. The expectations regarding results, prerequisits and work-ethic will be modulated based on whether a MA/SA or BA is written.

 

Application:

Please send all previous transcripts of records and your full CV to tomas.slimak@tum.de with the subject Application MA/SA/BA "name of thesis". Write a few sentences about what motivates you to apply for this thesis and why you would fit the topic. Please be specific in citing the experience/expertise that you have which would be relevant to this topic.

 

After submitting your application, it will be reviewed and if you are deemed suitable for the topic, you will be invited for an interview. Please be aware that part of this interview will be an oral evaluation of your background and understanding of concepts relevant to the thesis. The more preparation, creativity and initiative you are able to show, the better.

 

If you are interested in multiple theses that I am offering, do not send multiple applications, just name all the titles in a single mail. Applications and theses can be submitted in English or German as well.
