Instrumented Impact Test Data for CFPA6 Crash Box Systems

Abstract

This dataset contains time-resolved measurements from crash tests performed on three crash box systems (specifically numbered 5, 6, and 7). The data includes various physical quantities recorded during the impact events. Each quantity is available for two measurement points and includes both raw and filtered signals.

The impactor was instrumented using two KYOWA damped accelerometers. The acceleration data were used to calculate force, displacement, and the energy absorbed during impact. A CFC180 filter was applied to the acceleration signals for data smoothing and noise reduction.

The columns in the dataset are as follows:

Impactor Acceleration 1 – Raw acceleration data from the first impact sensor.

Filtered Impactor Acceleration 1 – Filtered acceleration data (CFC180) from the first sensor.

Impactor Acceleration 2 – Raw acceleration data from the second impact sensor.

Filtered Impactor Acceleration 2 – Filtered acceleration data (CFC180) from the second sensor.

Average Impactor Acceleration – Mean of the filtered acceleration data from both sensors.

Velocity – Integrated velocity profile of the impactor.

Displacement – Integrated displacement profile of the impactor.

Force from Impactor Acceleration 1 – Force calculated using the first acceleration signal and impactor mass.

Force from Impactor Acceleration 2 – Force calculated using the second acceleration signal and impactor mass.

Average Force – Mean of the forces derived from both sensors.

Energy – Energy absorbed by the structure, obtained by integrating the force over displacement.

Three types of crashbox samples were tested (see also Fig. 8):

Crash box 6: Fully riveted crash box system

Crash box 7: Crash box system without rivets

Crash box 5: Fully riveted crash box system with an aluminium plate (176 × 78 × 3 mm) welded on the top ring
