Excitation Test Rig

In this test rig up to six servohydraulic cylinders (100 kN maximum force, 400 mm maximum stroke) can be used for investigations of complete vehicles and components. Passengers cars and light trucks with up to three axles can be investigated. Beside vertical excitation logitudinal excitations are possibel as well. A 900t-foundation seperates the oscillations from the bulding. Applications are: Endurance tests of vehicles or components, optimization of damper or spring characteristics, comfort.

Test Rig Data

Complete Vehicle

  • Wheel loads: 100 kN / wheel; up to six wheels
  • Stroke: 400 mm
  • Frequency: up to 20 Hz
  • Foundation: fixed 900 t or 300 t (sprung) elastically joined with 600 t (unsprung)

Components

  • Loads: 10 – 100 kN
  • Stroke: 100 – 400 mm
  • Frequency: 20 – 40 Hz
  • Foundation: fixed 900 t or 300 t (sprung) elastically joined with 600 t (unsprung); more smaller foundations

Inidividual

The different servohydraulic cylinders can be arbitrarily combined by suitable mechanical elements.

Forklift

Example: Endurance Test of a Forklift

This test rig is used for endurance tests of forklifts (cf. Samadi Tehrani, N.: Methode der Betriebsfestigkeitsprüfung von Flurförderzeugen unter Berücksichtigung kundennaher Beanspruchungskollektive, Ph. D. thesis, HSU, 2010)
