With the development of new vibration test techniques there is real interest in understanding how different test techniques correlate with field performance. Real sample correlation studies are an ideal approach to test evaluation but present challenges of time, cost and sample requirements: these are rarely reported in the public domain. Pira is undertaking studies to develop vibration response systems to provide a way of comparing different test methods. This paper presents the findings of two systems; one based on the movement of a threaded weight and one on surface scuffing.
