Engineers in product reliability use accelerated vibration testing to predict the product’s life expectancy and anticipate potential failures with standard use. Properly developed accelerated test profiles can simulate a lifetime of damage in a fraction of the time. This presentation will cover field data analysis and the steps to convert recorded data into accelerated vibration tests using appropriate levels. The goal is to properly replicate the real-world environment on a shaker in the laboratory. Engineers running accelerated tests for product reliability will gain insight into test development processes and validation techniques, leading to more realistic test profiles.

• Components accumulate fatigue until failure when subjected to continuous stress
• Accelerated test profiles can replicate field environments while saving time
• Engineers can over-accelerate test profiles and risk unintentional damage, or they may have room to increase the acceleration safely
• Properly replicating field data on a shaker in the laboratory requires the correct selection of test type and parameters
• Test acceleration levels can be validated using a shock response spectra or extreme response spectra
