Transient Replication Control
Transient replication control allows replication of a range of field-measured shock transients on a laboratory shaker system - such as pyrotechnic events, road bumps and earthquake transients. A convenient model library allows automatic creation of special waveforms. The control and display features are the same as for the classical shock application.
Uses
- Replicating measured field data on a laboratory shaker system
- Replication of drop shocks, pyrotechnic transients, and other high frequency shocks
- Automotive applications such as door slam testing
- Seismic transients including Bellcore
Features
- Import of field data in ASAM-ODS XML, UFF ASCII, UFF Binary, ASCII, Excel CSV, MATLAB, NI-TDM, .WAV files, Pacific Instruments format, TEAC format
- Sampling rates up to 102 kSPS with up to 65k data points (4096 points standard)
- Compensation to give zero final velocity and displacement
- Processing tools including DC removal, high and low pass filters
- Model library including chirp, triangular bursts, and Bellcore seismic waveforms
- Display of time histories as acceleration, velocity, displacement
- Option for shock response spectra plots
- COLA output pulse to synchronise external equipment
Transient replication control imports field data in a wide variety of formats including ASCII text, Universal File Format (UFF), ASAM-ODS, and other formats. During importing, the software automatically digitally resamples the data at up to 104k samples per second, to match the hardware of the Type 7541 and 7542 vibration controllers. Once imported, user-selected compensation can be applied to make the waveform suitable for use with a shaker system.
