제진재 경량화를 위한 차체 판넬 형상에 관한 실험적 연구
강철우(Cheol Woo Kang),민경재(Kyung Jae Min),서강혁(Kang Hyeok Seo) 한국자동차공학회 2003 한국자동차공학회 춘 추계 학술대회 논문집 Vol.- No.-
The experimental study on the automotive body panel shape has researched a way to reduce the damping material. Among each differently designed panel shapes, tile curved panel shape, with high rigidity, or dynamic stiffness, and uneven deformation mode, has found to most reduce the vibration energy and damping material application.<br/> This study shows how could the panel shape influence the NVH performance, which would be measured according to several specifically designed panel shapes in order to compare with the conventional bead panel. And this research proposes the way to optimize the damping material to minimize its weight

자동변속기차량의 댐퍼클러치 직결역 확대에 따른 실내부밍 개선

For the purpose of enhancing the fuel economy in compact cars, it has been tried to expand the lock-up rpm of damper clutch in automatic transmission. But this way is likely to cause the interior booming noise accompanied by the body vibration. It is why lowering the engine rpm, where the damper starts to be locked up is, causes powertrain vibration increases due to the shortage of the engine power needed by the vehicle load.<br/> Therefore, in this study, the causes and paths of the booming noise and body vibration coming from expanding the lock-up rpm will be investigated. That is, the following questions will be examined.: How much the vibration of the powertrain increases, how the vibration of the powertrain transfers and thus, how and how much the interior booming noise increases.<br/> Specially, using RMA(Running Mode Analysis) method, the principal vibration path and the resonance of vehicle body will be investigated. Through investigation, this study will propose a few kinds of structural modifications and among those modifications the optimized modification will be adopted as the refinement of the booming noise and the body vibration.

This research is based on determining how the “20th Gyenggju World Taekwondo Championship” sponsorship has positively affected the Taekwondo image to transfer to Brand Image and Brand Behavior and present actual proof that the results are due to tournament sponsorship. Also, if there has been any image transfer, this research will identify the similarities between the Events and Brand Image, and identify the relation between the image transfers in order to provide an actual guideline to companies who need to make logical choices when it comes to Taekwondo athlete tournament sponsorship. In order to measure the effects of sponsorship in the “20th Gyenggju World Taekwondo Championship” a method which measures results on experimental approach has been used. Due to preliminary investigations, we have selected “Samsung” which had a deep relation with the “20th Gyenggju World Taekwondo Championship Athlete Championship” and “Warner Bros. Entertainment” which had no relations. The subjects of this research were tested before and after planning this research. The data collected was processed through SPSS Window 18.0’s technical stat analysis, reliability analysis, independent sample t-test and comparative sample t-test and concluded with the following results. First, it showed that there was a noticeable statistic relation regarding the image transition affected by TAEKWONDO tournament sponsorships. Secondly, statistically there was a significant image transfer in regard to how much the events and brand image were related. In conclusion, as a result of marketing communications of such sport events, sponsorships had a positive affect on brand image and brand behavior, and such strategies could help companies expand their brand value.
