A MATLAB TOOLBOX FOR SHOCK RESPONSE ANALYSIS DEDICATED TO SPATIAL APPLICATIONS

摘要

In this work, a toolbox is presented and consists of a package of procedures allowing calculation and analysis of shock response spectra. The shock response spectra are calculated from acceleration-time data and are used to validate equipments embedded into satellites and launch vehicles used during spaceflights. The data are collected during pyroshock tests. The toolbox offers a set of functions to do the data acquisition toolbox and have been developed with MatLab It is coupled to an acquisition NI PXI multichannel signal analyser, which offer the undeniable advantage to be robust and easy to control. The toolbox is divided in two subroutines. The first one is used to acquire data during tests and the second one allows the post-processing. This paper also presents some illustrative examples showing capabilities of the new system.
