Derivation of Environment Descriptions and Test Severities from Measured Road Transportation Data

Abstract

This paper discusses the vibration and shock environments perceived by equipment when it is transported by wheeled vehicles. Methodologies are presented for deriving environment descriptions and test severities from measured road transportation dynamic response data. Measured responses from a data-gathering trial are used to illustrate a number of useful signal-processing techniques and the compilation of environment descriptions that quantify the severity and character of measured data. The environment description is used as the basis for the compilation of a test severity definition in terms of a random vibration spectrum and duration.
