Comparison of the Response of a Simple Structure to SingleAxis and Multiple Axis Random Vibration Inputs

摘要

Random vibration experiments were performed on a simple structure to compare theresponse to single axis inputs and multiple axis inputs. The experiments were performedon a six degree of freedom (6-DOF) electrodynamic shaker described in a companionpaper [1]. The simple structure consisted of a lumped mass mounted on the end of a shortrectangular beam. A finite element analysis of the structure was also performed. Theexperimental and model results are discussed in the paper.
