Fatigue – Equipment

In the course of the degree program shipbuilding and maritime technique the University of Applied Sciences Kiel runs a fatigue laboratory which is under the management of Prof. Dr. Ing. Berend Bohlmann. For the past years the laboratory has been transformed from a training facility for chartered engineers into a facility where doctoral students and Bachelor and Master graduates are able to work on projects of various nature and extent. In addition to analyses on fatigue and stiffness studies on fatigue strength and constriction are conducted.

In order to run tests on fatigue strength multiple test stands and simulation options are available in Kiel. This equipment can be used for projects of the Crossborder Fatigue and Vibration Testcenter.


Hydropuls PZ 200/400

This universal test bench is operated hydraulically and is designed for dynamic, full-scale experiments. It is fully gimballed to a portal mounted to a base plate decoupled from the building.

Statical strength (max.): ±200 KN
Dynamic strength (max.): ±160 KN
Max. distance: ±200 mm
internal and external force measuring systems
Control system: EPL dynaSax D2
Testing stand software: dynaSax D2
Manufacturer: TIRA WPM Leipzig

Width: 3.5m
Height: 3.0m

This machine is suited for static analyses, single-stage tests, block programs and operational load simulations on semi intricate samples and full-scales.


Resonance Test Systems

The universal resonance test systems Power Swing 100 MAG is stimulated by electromagnetics. It is used to perform strain, bending or torsion vibration resistance tests on components and material samples.

Statical loads (max.): ±100 KN
Dynamic force amplitude (max.): ±50 KN
Dynamic hub (max.): ±2 mm
Test frequency: up to 300 Hz

Width of sample space: 530mm
Height of sample space: 660mm

This machine is commonly used to identify Wöhler curves. Also it is possible to determine the service life from block programs or random weights.

The universal resonance testing system Power Swingly 5Mot uses an engine to perform strain, bending or torsion vibration resistance tests on components and material samples.

Statical loads (max.): ±5 KN
Dynamic force amplitude (max.): ±2,5 KN
Dynamic hub (max.): ±10 mm
Test frequency: up to 110 Hz

Width of sample space: 550mm
Height of sample space: 670mm

This machine is commonly used to identify Wöhler curves. Also it is possible to determine the service life from block programs or random weights.


FEM:

Using FEM parts can be analysed with a HPC Research Cluster (28 cores and 256 GB RAM) to gain insight about:

  • lineal fatigue
  • non-lineal fatigue
  • nominal strength
  • fatigue strength
  • diversions
  • vibrations
