Abstract

The variability that exists in the memory and the programmed recording parameters in various types of data recorders has not been well defined. This study investigated the effect of these differences on the final power spectrum density (PSD) generated by environmental data recorders (EDRA). Random vibration levels from both an electrohydraulic vibration table and a 40-ft truck shipment were measured using two types of data recorders. The PSD levels, both numerical and graphical, developed from various recording control parameters were compared.
