The crash pulse in a vehicle-vehicle collision represents the variation of acceleration over time, from the moment of impact until the moment of zero velocity, or separation of the vehicles. The paper presents some methods and practices for the collection, retrieval, archival, and analysis of crash data, from crash tests and from real road events. The metrics used for crash evaluation, derived from the recorded crash pulse, include: maximum value of moving average acceleration, delta-v (the change in velocity), displacement, energy density, power rate density. Crash pulse based analysis can simplify the integration of crashworthiness into vehicle design. Data sources used by authors were mainly the crash tests performed at Transilvania University.
