"SpletIt’s important to understand that random vibration is not well predicted, and neither are its effects on hardware. In a random vibration test, at a given frequency, NASA-STD-7001B (Ref. 2) requires the input acceleration PSD to be controlled only to within +/-3 dB of the specified level at any given frequency.

SpletIn the tracking test stage of the standard EMU, when the train is running on a railway, the key rotating parts of the bogie are monitored and the collected vibration data are shown in Figure 19. The vibration data at 2 s and 5.2 s are disturbed by random large impact, resulting in a larger amplitude than other time periods. Splet30. jun. 2012 · These tests showed that random vibration could indeed pose a significant threat. The second part of the research aimed to better understand the dimensional stability response of specific structural elements - namely materials and bolted joints - to random vibration. This required the development of novel test setups and metrology techniques.
