DEKRA developed the Bump Test software in-house and can customize the package to meet specific needs. Bump testing can be performed in 1 shift.
Acceleration transducers are mounted temporarily on each tested bar-end to measure the radial, tangential, and axial directions. An impact hammer with an integrated force transducer excites the bar-ends. The FRF spectra show the normalized natural vibration response of the end-winding induced by the impact.
In principle, there are no limitations to the types of generators on which bump testing can be performed as long as conditions of accessibility and mounting of transducers are met.
