GRMS and G2/Hz Units | Vibration Signals

Time-domain vibration data is displayed in the acceleration unit G, often referred to as Gpk (“G-peak”). Frequency-domain vibration data is often displayed as a PSD plot with units of G2/Hz. Engineers also refer to the GRMS of a random vibration test. This video discusses the units of G2/Hz and GRMS, how they are derived from time data, and their importance.

Vibration Research University offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle sine testing, random testing, preventative maintenance, multi-axis testing, calibration, and more.
