프론트 사이드 멤버의 레이저 열처리에 관한 연구

Recently, laser heat treatment is applied by various industries. In automotive industry, there are two main categories: environment friendly and the high safety of vehicles [1]. In order to meet those needs, it has developed environment friendly manufacturing and surface hardening methods. Laser heat treatment is the local heat treatment[2] which is very small deformation because that is the characteristics of material self-quenching. It is possible to make up for the fault that is overall brittle characteristics in hot forming manufacturing and large deformation in high frequency heat treatment. so we will apply a front side member that is important to crash-characteristics. Also this study suggests new simple crash test method which is possible to apply to other crash parts.
