Determination of seat back resonance through modal analysis
Testing standard:
PR 038.2
Product information
Measurement of the first resonance frequency of the seat back vibration by means of a modal analysis using impulse hammer or, if required, shaker excitation to ensure the vibration comfort requirements for the seat structure and the complete seat. Presentation of the results as a frequency response function (yield over frequency), optionally phase over frequency, per spatial direction.
