Drive File Generation

Measurement system for road load data acquisition and drive file generation

The compact and flexible configurable hardware with 4-64 input channels and the easy-to-use software make the BSR SUITE a tailor-made tool for the mobile acquisition of accelerations, excitation forces, relative motions and sound in the vehicle. Editing multiple records in parallel enables very easy and effective ways to compare and combine different recordings. Cut, Copy and Paste of relevant time signal sections from different recordings into a new file is intuitive and easy. Signal statistics provide overview of main statistical values such as RMS, PEAK, MAX, MIN and CREST-factor for each channel with just one mouse click.
Integrated know-how and procedures to transfer vibration conditions from the road to the lab improve the simulation quality and correlation to road testing. Calculation of equivalent PSD-spectra over user selectable time sections, averaging of multiple sensor locations, rescaling of the resulting vibration level and smoothing of the PSD shape is done by only a few clicks. Amplifying, resampling and export to various data formats allows the ideal adaption of recorded data for direct transfer to MB vibration control systems. For multi-axis vibration testing data can be exported to the MB MIMO Drive File Processor for further processing.
