Abstract

MDB (Moving Deformable Barrier) is widely used over the world for the tests like frontal offset impact, side impact as well as frontal oblique impact. As autonomous vehicles are expected to come into the market in near future, new test protocols are required to secure the safety of the new type vehicles. MDB can be a versatile option for the new tests. In order to better understand the MDB, NHTSA oblique impact is chosen for the case study. NHTSA oblique impact test is about to be published and will be one of the newest test protocol using MDB, which bears technical know-how's built up from previous studies of MDB impacts. Compressive deformation behavior of the honeycomb of MDB is studied changing thickness of honeycomb structure. Delta-V is a good measure of impulse to the vehicle and is compared with varying weight of the MDB as well as its initial impact speed. Equivalence of delta-V with respect to momentum and kinetic energy is studied as well.
