  • In present, evaluation method for car cabin air quality has been developed in ISO, China, Japan. Also The management standard for new produced car has been applied since 1, July, 2010. To manage car cabin air quality, It is important to evaluate VOC emitted from interior material. In this study, complete component of door trim armrest was evaluated in accordance with ISO 12219-5, cut component was evaluated in accordance with ISO 12219-3. The vapour gas was collected with stainless tube packed with Tenax TA and analyzed with TD-GC/MS. It was confirmed that emission rate of each compounds was difficult in each evaluation method. As a result, to evaluating each components composing door trim armrest, main sources of emitting VOCs in door trim armrest were PP substrate and adhesive.

  • 자동차 측면충돌시 인체의 상해를 줄이기 위하여 도어 시스템 부품 중에 도어트림이 충격을 차단하고 인체를 보호하는 역할을 하고 있다. 차체 판넬이 변형되어 도어트림에 전달되는 충돌 에너지를 패드가 흡수 하는데 중대한 기능을 한다. 이전에 충격흡수 패드는 외곽부위의 수평면에 의존하여 설계되었으며 이 구조는 점진적으로 충격을 흡수 하는데 문제점이 발견 되었는데 트리즈의 6단계 창의성 기법을 적용하여 패드의 주요 특성을 찾아내고 그 특성에 모순을 해결하여 차종에 적용할 수 있는 기본 단면과 설계 자유도가 높은 충격흡수부재를 개발 하였다.

  • In this paper, we develop a durability test method that can verify the noise caused by the repeated load on the door trim grip handle. The test method was developed in consideration of the load mode and durability test cycle applied to the grip handle. In order to verify the validity of the method, we demonstrated the door trim grip handle noise that occurred in the field claim with the product in the early stage of mass production through the developed test method. Finally, It is used to detect and improve the noise of subsequent development products through the currently developed test method.

  • For the senses of beauty and texture, internal components of small passenger cars are manufactured by texturing plastic with drawplate but those of deluxe passenger cars are manufactured by bonding pre-embossed skin to the surface of drawplate. As the pre-embossed skin is bonded at high temperature and pressure, the pattern of skin is distorted. The corner part is hardened and its dimension tolerance is changed by resulting in the increase with its defective rate. This study provides the method to design and manufacture the door trim track by vacuuming the non-patterned skin to upper-side drawplate which forms the pattern of descending skin. It is pressed to the plastic product with hot-press method and the damage of bossed-pattern is prevented. Valuation in this study has been done by analyzing, designing and experimenting method.

  • Injection pressure is one of factors that influence part quality. In this paper, injection pressure was minimized by optimizing valve gate locations. In order to perform design optimization, MAPS-3DTM (Mold Analysis and Plastic Solution-3D) was used for injection mold analysis and PIAnOTM (Process Integration, Automation and Optimization) was used as process integration and design optimization. Also we adapted meta models based on design of experiments for efficiency. By using introduced methodology, we were able to obtain a result so that maximum injection pressure reduced by 28% compared to the initial design. And the validity of the proposed method could also be demonstrated.

  • A nation have the regulation for a vehicle safety and interested in the side impact of a vehicle. But we spend a lot of money and time for the side impact test. So we must design a vehicle parts regard to the side impact test. This paper describes a new test method for side impact test. We used DFSS(Design For Six Sigma) process for design of door trim armrest. We searched the door trim armrest control factor and made the experiment plan. We researched the optimal design factor and improved the abdomen injury value of the human dummy.

  • In order to formulate the compounded polypropylene(C-PP) which is suitable to an automotive door trim panel, 9 sorts of properties were measured after manufacturing the C-PP using an extruder and an injection machine with polypropylene(PP), ethylene-octene rubber(EOR) and talc. Mixture design, especially extreme vertices design, in DOE with MINITAB - commercial software was used to analyze the data. The relations between each property and each component, for example, $y=0.00907222x_1+0.00870556x_2+0.0155722x_3$ for specific gravity, were found out by the regression analysis and the variance analysis. The optimized formulation of the C-PP for an automotive door trim panel was acquired at PP(77.6962), EOR(11.0238) and talc(10.2800) by use of the response optimizer(mixture) in MINITAB.

  • 일반형 자동차 내장부품은 외부가 플라스틱 사출 성형한 형태로 사용되지만, 고급 차종은 내장재의 미감이나 질감을 위하여 사출물 표면에 엠보싱 무늬가 형성된 표피재가 수지에 추가로 부착되어 제작된다. 부착하는 방법은 한 장비에서 저압 사출 후 플라스틱이 완전 응고 전에 표피재를 넣고 압입하는 저압 사출법과 표피재 수지를 기 사출된 제품위에 놓고 압착시키는 압착법이 있으나 이 두 방법 모두 엠보싱 무늬가 형성된 표피재를 넣고 작업하기 때문에 고온 압착시 기존 무늬가 찌그러지고 코너 부위가 경화되어 기존의 질감을 얻지 못하며, 치수 공차가 변형되어 불량률이 증가하므로 이를 시급히 개선할 새로운 제조 기술의 필요성이 대두된다. 본 연구는 가열 압착기로 지그 및 금형을 새로 개발하여 도어 트림 제조시, 기 사출물을 금형 쪽으로 기 조직을 삽입한 후 엠보싱 무늬가 없는 원소재 표피재로 상부 금형 쪽으로 소재조직을 진공으로 흡입하여 무늬를 성형한 후 하강시켜, 기 사출물에 압착시키는 가열 압착으로 엠보싱무늬의 손상을 방지하는 금형을 제안하였으며 그에 대한 해석, 설계, 실험을 통하여 성능을 평가 분석 하였다.
