Optimization of Bumper System Under Various Requirements 2001-01-0354

The importance of bumper system lies not only in the styling and the protection of front end of vehicle from reasonable impact, but also in the protection of occupants - behavior of bumper-frame joint under low speed impact affects the must-fire/non-fire condition of airbag. Furthermore, new regulation, ‘Pedestrian protection’ which is anticipated to work in EC as well as the US and Japan, impose another heavy load on the role of bumper system. Under these requirements it's very hard to design an appropriate bumper system for all requirements since respective requirement is not necessarily compatible with each other.
In this study, structural parameters of bumper system will be studied via analytical methods and through the comparison of parameters under two requirements, low speed impact performance and pedestrian protection, interdependency of parameters on a certain performance will be studied.
