The Correlation between Vibration Tests and Field Performance
At the 24th IAPRI Symposium, 2009, the Distribution Research Working Groupconcluded that there was a need to understand better the correlation between the various vibrationtest methods and real life vibration response. The group observed that established broadbandrandom vibration tests had a proven track record of successful use but that there were questionsand issues around confidence in the applicability of the standard tests to all situations. Thesequestions were based on reported issues of poor correlation with field performance by somelaboratories and in the context of research and new equipment developments addressing concernsover kurtosis, non-stationarity, test acceleration and shock on vibration. This paper discusses andexplores the topic of establishing the correlation between laboratory tests and field performanceand justifies the need for correlation studies in the context of current thinking and research invibration testing. The results of early correlation studies undertaken at Pira International using asimple vibration response test rig are presented. At mid-range vibration intensities the rig gives aresponse which has a reasonable match with the fatigue model on which test time compression isbased. The outline design of a rig intended to simulate scuffing responses is presented.
