Relationship between Strain and Velocity for Ground Vehicle Vibration

This paper uses experimental vibration data to evaluate the relationship between strain and velocity on a ground vehicle platform. The data also are used to compare the acceleration and the strain. Comparisons are made in the time, frequency, and damage domains. The results clearly show the strain data are more closely related to the vibratory velocity than to the acceleration, but the analysis is complicated somewhat by characteristics of the experimental data set.
