연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract ▼ AI-Helper 아이콘AI-Helper

The automotive front bumper guard is the most important part of the vehicle for protecting the life of driver when a traffic accident happens. In order to ensure safe driving, this part must possess sufficient strength and durability. This study was carried out with structural and fatigue analyses b...

제안 방법

  • 1. The failure characteristics of each of the front bumper guard models could be identified by performing simulations of structural and fatigue analysis on each of the models by shape.
  • First, a fixed support condition was given to the part where the front bumper guard was fixed, and then a 500-N force condition was applied assuming that the impact or load was applied to the front part of the front bumper guard model. The simulation analysis was also conducted by applying the same boundary conditions to the other two models, the B-type and C-type front bumper guard models, and strain, equivalent stress, and durability in the fatigue situation in each of the front bumper guard models according to a shape were studied. In addition, Table 1 presents the physical properties applied to each of the front bumper models, in which structural steel was applied as the material for the models[5-10].
  • This study conducted simulations of structural and fatigue analysis on the front bumper guard models by shape, and the following conclusions could be derived.
  • Thus, sufficient stiffness and durability must be provided. This study designed front bumper guard models by shape in light of this point to conduct simulation structure analysis and fatigue analysis, by which the strength characteristics and durability of the front bumper guard model were identified to contribute to the optimal design and development[1-4].
  • This study designed three types of models: A, B, and C types by shape, as shown in Fig. 1, with reference to the front bumper guards that were selling in the market using the CATIA V5 R11 3D design program.
  • A front bumper guard is mounted in front of the bumper so it has to have sufficient stiffness against the impact and repeated load that is applied during driving. Thus, this study also conducted fatigue analysis. Fig.
  • All of the three front bumper guard models showed a trend of vulnerability in the center portion of the front side. To overcome this, additional studies should be conducted from various viewpoints, such as renovation through changes in design shape. Furthermore, the data derived through this study are expected to be utilized in the design and development of a more advanced front bumper guard in the future.
