초록
The structural performance of a vehicle can be evaluated by the static and dynamic structural analyses which predict the amounts of deformation & stiffness, and the static analysis should be done first. Another important aspect to be considered in the design process is crashworthiness, because a structurally sturdy vehicle body may be overdesigned with the excessive strength and durability standards. The ideal condition of a body structure is to absorb the impact load at a certain level of local deformation, to distribute the load to each structure adequately, and to prevent the excessive stress concentration and deformation. This paper is the result of the consideration of vibration characteristic for structure stiffness estimation of automotive body through the finite element modeling.
