Response of Cable Harnesses Subjected to High-velocity Impacts

Abstract

We compared numerical simulation results obtained using AUTODYN-3D, which is used for impact analysis of complex physical systems including fluid and solid materials, with experimental results obtained using a two-stage light gas gun. The response of electric power supply cable harnesses subjected to high-velocity impact at 4.01 km/s is shown and discussed. In addition, AUTODYN-3D was applied to the numerical simulation of the hypervelocity impact of micrometeoroids and space debris (M/OD) at 15 km/s and 20 km/s, respectively. Material models used in the numerical simulation are also discussed and investigated in order to cover a wide range of impact velocities, including shock-induced vaporization.
