| Summary: | The growth of automotive industry not only increase its usage, but also the
risk of accident and injury experienced by its users. One of the attempt to reduce
risk of injury during accident is by introducing a crashbox as energy absorption
device. However the energy absorption capacity of crashbox is limited by design
restriction, especially in terms of dimension and total permitted mass, depending
on the available placement space in the vehicle compartment. Innovation that can
be done to improve the performance of crashbox is by adding lattice structures as
fillers. Moreover, currently the studies of lattice structure are developing due to
the availability of additive manufacturing technology that allows the production
of complex lattice geometries at a relatively lower cost and quicker process.
In this study, numerical simulations and experiments will be conducted on
the usage of lattice as a crashbox reinforcement structure under quasi-static axial
loading. The lattice structure to be used is a combination of hexagon and
reentrant, and is produced by additive manufacturing using UV-sensitive
photopolymer resin materials. Furthermore, validation will be carried out
between numerical simulations and experimental models and the studies of lattice
thickness variations. |
