A Study on the Optimization of Door BIW Structure Using Thin Casting Method

SANGJIN LEE･JeongMin Kang･DongHa Kang･JungHan Kim･SangYoung Im･SeongHwan Seo･HeeBeom Yang (Hyundai Motor)

The integrated molding reduced the number of parts based on door INR ASSY from four to one, and the entire welding point and adhesive were removed. In order to cope with the process and secure the stiffness of major parts, the thickness was flexibly designed to be 2 to 3T as needed. The number of door assembly processes is reduced from 13 to 8 due to the change in the construction method.

The Development of the TPV Door Inner Belt WeatherStrip meets Wind Noise Targets and Prevents Glass Sliding Squeak Noise Simultaneously

Jeehoon Seong･Sanghyun Lee･Boram Kang･Jungdae Kim･Jaehoon Kim･Youngchel Sin (Hyundai Motor)

As vehicles become electrified and sophisticated, the wind noise problem while driving is becoming more important. Among them, the sound insulation performance of the door's inner belt weatherstrip is essential, as it blocks noise from penetrating into the cabin through the door. However, it became lessened as a consequence of minimizing the lip overlap between the door glass to decrease the squeaking noise when the glass is being operated(going down). In this study, the lip overlap and contact load will be defined first to satisfy wind noise performance and simultaneously develop a standard shape of section that does not generate squeak noise.

Package and design study for application of B pillar less door

YONG HYUN NAM･HYONG DON KIM･CHUNG SIK YIM･KYU HOON CHO (Hyundai Motor)

We are working hard to secure advanced product competitiveness in preparation for the upcoming era of autonomous driving. In the era of autonomous driving, the space inside the vehicle for passengers to engage in various activities other than driving is an important factor, and B-pillarless doors are becoming an essential element for securing interior space. To implement this, we conducted research on vehicle packaging elements and design implementation, and were able to reach a conclusion close to reality by manufacturing an actual vehicle. Through this research, we will introduce the packaging and design elements necessary for B-pillarless doors.

Purpose Built Vehicle (PBV) is an eco-friendly vehicle that can be delivered at a low cost to meet business objectives and needs. It's a multi-purpose mobility vehicle with a simple architecture that can be designed to meet a variety of requirements. It can also provide solutions that increase customer business value and maximize the efficiency of business operations such as costs. In this paper, we will discuss "L-shape side gate automatic opening and closing technology" of the Micro PBV. In particular, we will deal with high durability opening and closing technologies that can improve the operation rate of PBVs and technologies that increase cargo space.

ABS樹脂をはじめとする樹脂材料は自動車の振動吸収性や耐衝撃性を確保するための内外装部品に用いられている．本研究では，打撃試験を実施して樹脂部材をボルト締結した構造体の減衰性能が樹脂の粘性減衰と部材間の摩擦減衰の重ね合わせで決まることを明らかにし，有限要素解析を用いて粘性減衰と摩擦減衰の内訳を調べた．
