Beschreibung

To simplify the designing of electronic components for forklift trucks with regard to their  specific  operating  conditions,  a  test  forklift  truck  has  been  equipped  with  industrial-standard instruments to measure the occurring electrical and mechanical stresses. To evaluate the fatigue potential of these components the acquired measurement data were analyzed in the time and frequency domain and compared to a classification with the rain-flow counting algorithm. To compare the failure characteristics of the examined electronic components, lifecycle  tests  was  carried  out  on  an  electrodynamic  shaker.  These  experiments  were  performed on individual electronic components, similar to the components of the drive modul of the test forklift truck, which were operated at the same time under typical operating electrical loads. Additionally, the influence of vibration and shock excitation could be checked for the control behavior of these components.
