Acquiring field data and creating vibration tests
Todays vibration testing standards are intended to simulate the field environments a product, device or package will experience in the real world.Products are tested for a wide range of reasons, from R&D, to production, to life testing.Understanding how a product will react to the real world and the end use environment is critical.It is common practice to collect field data from the end-use environment to verify the testing conditions have accounted for all the real-world conditions.This paper and presentation will discuss the variety of testing options available for the collected data.This includes playing back the recorded data on a shaker in real time, also referred to as long time-history playback.Other options discussed will be FFT transformation with average and peak-hold methods, the influence of kurtosis on the recorded data, and the proper use of the fatigue damage spectrum to generate a random PSD.
