Shock & Vibration

DSPCon’s shock and vibration software bundle provides an extensive solution for engineering personnel involved in structural shock and vibration (S & V) application modeling and prediction. Specifically designed to optimize test data for better analytical calculation and display for a variety of aerospace-related applications, DSPCon S & V software processors reflect over 20 years of refinement and leadership in digital signal processing software and incorporate classical algorithms with advanced post processing capabilities to provide interactive and batch analysis of sine-sweep and shock tests.

The sine analyzer included in our shock and vibration software bundle processes CATS and DATX sine-test-data files to provide single- or two-channel spectral analysis based on peak response or a narrowband-tracking filter. The drive frequency is determined by a proprietary “COLA” analyzer. The tracking filter has very selective response and can have constant or proportional-to-frequency bandwidth. Results include sine magnitude and transfer-function magnitude and phase-in graphical and output-file forms.

The Shock SRS feature processes the data in CATS files to produce shock response spectra. It applies "time-series pre-conditioning" functions designed to compensate for errors and distortions induced in the data by measurement and data acquisition processes. These "pre-conditioning" functions entail zero offset and band-pass filtering.
