Sample Data

Python scripts that generate synthetic time-history files in every format EnginPlot reads — RPC3, CSV, fstrm, and PLT. All data is entirely synthetic, no recorded or proprietary data of any kind.

Download the generators (.zip, 20 KB)

Requires Python 3.9+ and NumPy (pip install numpy). Unzip, then run any script directly — see the included README for details.

gen_automotive_csv.py

CSV · 10 s @ 100 Hz · six proving-ground maneuvers (launch, braking, constant-speed cruise, hilly terrain, double lane change, rough road) sharing one 21-channel schema.

gen_shaker_rig.py

fstrm · 14 s @ 512 Hz · a 4-post durability shaker rig replaying a rough-road profile, with the resulting seat/floor/dash accelerations and actuator load-cell force.

gen_hev_powertrain.py

PLT + .hdr · 16 s @ 100 Hz · a hybrid-electric powertrain simulation: standing start, WOT launch, a short cruise, then a regenerative-braking coast-down.

gen_road_load_demo.py

RPC3 (.tim) · ~15 s @ 1 kHz · a short durability road-load snippet — accelerate, cruise onto a rough patch, brake to a stop.

gen_perf_road_load.py

RPC3 (.tim) · ~4 h 10 min @ 1 kHz · a large (~600 MB, 15M-point) durability road-load file for performance testing EnginPlot at scale, not for a quick look.

Real recordings from elsewhere

For measured data rather than synthetic, these public sources publish vibration recordings free to download. They belong to their publishers, not to EnginPlot, and each source’s own terms apply. EnginPlot reads their CSV files; where a source offers other formats as well, take the CSV.

enDAQ — free vibration analysis files

Shock and vibration recorded in the field and on the shaker: aircraft exterior and seat base, a truck bed in transit, a car engine on a commute, UPS ground and freight shipments, MIL-STD-810G random and a 10 g sine test. Offered as CSV, .IDE and .MAT — use the CSV.
