A DSP based real-time 3D FFT system for analysis of dynamic parameters

A DSP based real time 3D FFT system is realized for the analysis of dynamic parameters. High thrust is required for launch vehicles and aviation application. The test and development environments involve high cost of civil structures, test facilities and the Devices under test (DUT). The mechanical failure in the DUT or the test facilities may lead to catastrophic failures. The present real time 3D FFT system is capable generating the real-time 3D spectrum and is tested for various inputs from vibration accelerometer and function generator. This paper details the design of the software, integration and test on of system and elaborates its applications.
