Bachelor thesis: Development of a 1D finite element tool for the calculation of arbitrary rotors

In his bachelor's thesis, Mr. Maybach worked on the development of a tool for calculating arbitrary rotors based on the finite element method. The developed tool enables the rotordynamic analysis of rotors with ball or journal bearings with one or more impellers, such as those used in modern turbopumps. Of particular interest here is the influence of fluid-lubricated journal bearings on the dynamic behaviour. Due to their properties, this type of bearing can generate considerable virtual masses in the order of several tons. The detailed analysis and consideration of these effects enables a more profound understanding of the interactions between rotor and bearing. Mr. Maybach's work makes a significant contribution to understanding the dynamic behaviour of modern machines.

We congratulate Mr. Maybach on his successful graduation and wish him continued success.
