Introduction to the application of the PTC Creo CAD system
- Acquire the knowledge and basic principles needed for modelling components and assemblies of simple to medium complexity. Develop 2D drawings from these components and assemblies
- 3D geometry profiles and rotated forms, tension members and parallel composite elements, material cross-sections, sketching tools, boreholes, edge bevels, edge filleting, models of machine elements, use of standard parts
- Insertion, deletion, suppression and modification of assemblies
- Generate 2D-drawings, add and modify drawing views, cross-sections, dimensioning, dimensional, geometric and positional tolerances, surface finish symbols, welding symbols, drawing border, text field, parts list
CAE (engineering design)
- Application and integration of a parametric 3D CAD system into the development and design process
- User-specific adaptation and use in project groups
- Assembly management, skeleton models and layouts as basis of parametric assemblies,
-
user-specific adaptation family tables and UDFs as user-defined adaptations / extensions
- Modelling and organisation of special geometry for complex modelling problems, model organisation with films
- Interfacing problem Creo - ANSYS (CAD - FEM), Creo - KISSsoft
CAE (Finite Element Method)

- Introduction to the application of the Finite Element Method using a professional FEM system using simple linear problems from structural mechanics.
- From the product model to the computational model
- Boundary conditions: fixtures, forces and pressures
- Representation of strains and stresses with the aid of contour plots, path plots, tables, interpretation of results
- Theory: numerical analysis of a simple 2D rigid frame
User support
The LKS supports users in the use of hardware and software in the exercises to the lectures in design theory, machine elements, design engineering, drive systems, machine dynamics and projects 1 and 2.
Machine dynamics
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.
Research and knowledge transfer
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.
