Sentence examples for random spectrum from inspiring English sources
Sigma clipping is most commonly used to make sure a shaker system will be sufficiently powerful to reproduce the required random spectrum.
This initial work has been extended in this paper to examine the effects of single and block overloads and random spectrum loading on crack growth.
On the basis of available fatigue design knowledge, the structural fatigue characteristics of hydraulic actuator was depicted based on a nominal force concept from the paucity of experimental dataset, and safe fatigue life of hydraulic actuator subjected to actual random spectrum load history was modelled based on a reliability concept.
The analyses and the results were presented for both constant and random spectrum holding time, as well as random spectrum idle time considering the Poisson arrival process.
