Machine dynamics
Test bench torsional mass oscillator
Presentation of oscillation phenomena with the aid of different experimental test benches. A single-mass oscillator, a double-mass oscillator, a testbench for the visualisation of torsional oscillations, and an experimental platform for the illustration of the lateral critical speed are available for this purpose.
The Engineering Design and Simulation Laboratory (LKS) collaborates with industry and other universities. The collaboration focuses on the use of computers in design and calculation.
The projects listed below have been carried out recently
Development of a new model of the hip muscles
Bone remodelling processes for hip replacements
Determination of the resonant angular frequencies of a rotor
Geometry transfer CT-FEM
Two doctoral theses on biomechanical engineering have recently been concluded.
“New methods for international product development”
“HEIBus” international research project (project duration 1 January 2017 – 31 Dec. 2019)
Five universities and seven companies from five different European countries collaborate in a large-scale research project. The objective is to improve the cooperation between European companies and universities and solve concrete research tasks in international teams.
The task of the Esslingen scientists is to solve concrete problems experienced by companies with several teams of international students. The teams compete for the best result and thereby also experiment with different methods of working: Some will meet personally, others will exclusively use virtual exchanges. The virtual work in particular is a new approach which is being tested in practice here. Another feature is that the student teams should come from different departments.
