The steering-wheel-steering-column assemblies fitted in automobiles must have a high energy absorption performance in order to minimize occupant chest injuries in the event of a collision. This paper proposes a novel built-in energy-absorbing (EA) component which causes the impact load transmitted to the occupant to vary in accordance with the crash severity and the occupant mass. A finite element (FE) model of the steering-column system is constructed on the basis of realistic product computer-aided design data, and a series of LS-DYNA simulations are performed to examine the dynamic responses of the steering wheel and steering column in body block impact tests performed using body blocks of different weights. The validity of the FE model is confirmed by comparing the numerical results for the torso force profile over the duration of the impact with the experimental results obtained in two standard body block tests. The validated model is then used to examine the energy absorption performance of the proposed EA device consisting of a hollow cylindrical tube patterned with an array of circular openings. The simulations focus specifically on the effects of the total holeopening area, the cylinder thickness, and the cylinder material on the torso force profile over the duration of the impact. It is shown that, given an appropriate specification of the design parameters, the proposed EA device satisfies the peak load requirement specified in the FMVSS 203 standard and absorbs 163 J and 235 J of the impact kinetic energy for body block weights of 24 kgf and 34 kgf respectively.

A side collision of an automobile poses a higher risk of injury than a frontal collision does. Throughout the world, governments and insurance companies tend to establish and implement new safety standards for side collisions in order to ensure the safety of the occupants of vehicles. Most of the standards aim to reduce the head injury criterion. Currently, curtain-airbag systems are widely used and known to be the most effective means to reduce the head injury criterion in the event of a side collision. A curtain-airbag design procedure which uses modern optimization methods based on a newly defined design scenario to reduce the head injury criterion risks of the occupants of vehicles is introduced in this paper. The design scenario has two phases. In phase 1, various elements of the curtain airbag are defined as the design parameters. The variables are determined in a discrete space using an orthogonal array as well as in a continuous space using optimization where each function is approximated. In phase 2, important variables are extracted via a statistical method and those variables are determined in the same manner as in phase 1. As a result, the head injury criterion of the occupant is decreased significantly. The final design is discussed from a practical viewpoint.
