In this paper, a passenger air bag(PAB) folding method using finite element analysis was suggested. As PAB is<br/> more complex in shape than other airbags, generally it takes much time and efforts than others and requires highly<br/> skilled experience to get folded finite element model. Fully folded PAB finite element model was achieved by<br/> performing the continuous series of simulations. So, Anyone without skilled experience in air bag folding process<br/> can get folded PAB easily by following the process. It can save time in PAB folding process and decrease errors in<br/> PAB deployment simulation, and is expected to contribute to the development of advanced air bag which has to<br/> consider out of position (OOP) situation.

The air suspension system automatically controls the vehicle height. This height control has the advantage of being able to keep the vehicle height constantly regardless vehicle load variation so that it can maintain in the design height. In addition, aerodynamic advantages can be achieved by lowering the vehicle height at high speeds. When driving on rough roads, the impact from the road surface can be reduced by raising the vehicle height. In this study, we propose a method to improve R&H performance by selecting optimal vehicle height. And also propose selected the optimal vehicle height according to the driving situation by linking the air suspension system with the driving mode function of the vehicle. Finally, propose a method to improve the R&H according to the driving mode.

The Element who is a environmental contamination and an automobile fuel efficiency improvement the automobile lightweight is to in the process of advancing. The magnesium alloy from in the utility metal with the lightest metal in the lithosphere element is abundant at 6th and has the vibration which is excellent and a shocking absorbability and the subject matter quality of electromagnetic waves screening characteristic etc. The overseas’s various magnesium cross members are executed a benchmarking evaluation in the object. Set the goal, physical properties and a parts lightweight of above on equal level with aim, Applied AM60B magnesium alloy, at the first among nation the lightweight magnesium cowl cross member with die casting method developed. Crash test results were excellent. Development result, Accomplished a lightweight 30% and reduced parts.
