Subcontractor of SPR’s contractor replaced the moulding tool of vertical base frame element. SPR had to collect experimental data in order to find the source of vibration revealed in-process quality control.
Free vibration and forced vibration data acquisition, data analysation and visualisation by NI LabView application.
Machine condition assessment according to ISO10816-3 and by comparison to previous measurement.
Measurement revealed tooth-meshing frequency and base frame resonance frequency collide in the normal operation speed. SPR suggested design modifications.
