Modal testing of the NPSAT1 Engineering development unit
Abstract
The purpose of this thesis is to validate a finite element model of the small
satellite NPSAT1. A modal test of this satellite will be conducted and the results
will be correlated to the FEM simulation results. Furthermore, this thesis provides
an overview of modal parameter extraction techniques and the theories behind
them. Impact testing is chosen to obtain the data. In the end, the FEM is found to
be inaccurate and suggestions are presented for improvements.
