Study of Vehicle-to-Vehicle Collision Performance Based on Balance of Front End Strength
Compatibility in vehicles crashes has been studied worldwide in recent years. In cases where primary energy-absorbing structures such as front end members were bypassed in front-to-front collisions, energy-absorbing efficiency declined compared to cases when no such bypassing occurred. A bumper beam that connects the front end members in the transverse direction can help prevent bypassing of primary energy-absorbing structures. The strength balance between front end members and a bumper beam was studied in this paper. It was verified in front-to-front offset vehicle collision tests that crash energy can be efficiently absorbed by balancing the strength of the bumper beam with the compression strength of the front end members.
