「작년도의 자가용차 1km주행에 요하는 타이어 튜우브비는 소형승용차가 1.27엔, 소형트럭 1.16원, 경자동차 0.6원으로 타이어 경비는 전년도보다 14~29%감소하고 있다」라는 조사결과가 운수성자동차국의 조사에서 명백해졌다. (「자가용 자동차의 점검정비실시현황등의 실태조사결과 1976년도」),여사히 타이어 튜우브비가 전년도보다 감소한 이유로써 ①주행거리가 하락하여 있는 점 ②타이어 가격이 하락하고 있는 점 ③타이어의 사용관리가 엄격하게 되어 있는 점 ④라디알타이어의 증가에 따른 타이어 수명의 연장등의 점이 지적 될 것이다. 이하 동조사 결과로부터 타이어에 관한 부분을 발기해 보았다.

Colors in design elements are visual non-verbal symbols both sensual and emotional. It is the first priority in the selection of products for the consumers, and also represents differentiated strategies and coherent integration symbols for the brand. Colors in advertising is an important tool to represent the long-term image management for the brand as well as the product image and concept of the advertise. The theme of this paper is to develop creative advertisement analyzing colors from automobile video ads. Analysis results showed that video ads with small cars under 2000cc preferred pastel colors with high saturation and brightness to emphasize on individuality rather than authority. On the other hand video ads with big and luxury cars upper 2000cc preferred dark colors with lower saturation and brightness. Small car video ads focused on product appearance showing the practical value of the car, big luxury car video ads focused on the symbolic image feeling the difference between the representation of the ads. Colors used in advertisement represents the sensitivity of the consumers. In video ads the concept of the color should be set by identifying on who the globule targets are and on what item you show by identifying the corresponding colors sensitivity to suit your advertising strategy will increase the value of the brand and products.

The purpose of this research is to evaluate a short-term export demand forecasting model reflecting individual passenger vehicle brands and market characteristics by using Vector Autoregressive (VAR) models that are based on multivariate time-series model. The short-term export demand forecasting model was created by discerning theoretical potential factors that affect the short-term export demand of individual passenger vehicle brands. Quarterly short-term export demand forecasting model for two Korean small vehicle brands (Accent and Avante) were created by using VAR model. Predictive value at t+1 quarter calculated with the forecasting models for each passenger vehicle brand and the actual amount of sales were compared and evaluated by altering subject period by one quarter. As a result, RMSE % of Accent and Avante was 4.3% and 20.0% respectively. They amount to 3.9 days for Accent and 18.4 days for Avante when calculated per daily sales amount. This shows that the short-term export demand forecasting model of this research is highly usable in terms of prediction and consistency.

Crashworthiness design is of special interest in automotive industry and in the transportation safety field to ensure the vehicle structural integrity and more importantly the occupant safety in the event of the crash. Front side assembly is one of the most important energy absorbing components in relating to the crashworthiness design of vehicle. The structure and shape of the front side assemblies are different depending on auto-makers and size of vehicles. Thus, it is not easy to grab an insight on designer's intention when you glance at a new front side member without experiences. In this paper, we have performed the explicit nonlinear dynamic finite element analysis on the front side assembly of passenger cars to identify the mechanical roles of major parts in relation to collapse modes from the viewpoint of reverse engineering. To do this, we have performed crash FE analysis for the two different assemblies of small car and heavy passenger car and have compared dynamic behaviors of the two.

This study deals with the accident models by vehicle type. The goal is to develop the accident models by vehicle type using the data of 143 4-legged signalized intersections in Cheongju. In pursuing the above, this study gives the particular attentions to explaining the relationships between the values of EPDO(equivalent property damage only) and the traffic and geometric elements. The main results analyzed are the followings. First, 6 negative binomial models are developed, which are all significant at the 90% confidence level. Second, the values of ${\rho}^2$ by vehicle type are 0.14307(auto), 0.35556(large van), 0.21684(small van), 0.205152(motocycle), 0.32338(light-duty truck) and 0.29046(heavy-duty truck), that are all analyzed to be statistically significant. Finally, the common variable included in all models is ADT(average daily traffic), and the specific variable(SV) of auto is analyzed to be the sum of lane width of main road, SV of large van is the average yellow time, and SV of small van is the difference in the number of lane between main and minor road.

In this paper, we studied process capability analysis for brake-pad manufacturing system and considered Weibull, normal and logistic distributions for density estimation of wear life of brake pads for a passenger car with a real data. These three distributions are seem to work well. Estimated percentiles of brake pads can be used to evaluate the design criteria and customers' need for brake pads.

승용차나 소형승합차에는 현가장치의 스프링으로 코일스프링을 많이 사용하고 있으며 최근 들어 승차감의 상을 위해 변위의 증가와 함께 스프링 정수가 증가하는 경화 특성 스프링(hardening type spring)을 많이 채택하고 있는데, 이 특성을 나타낼 수 있는 방법 중 하나가 등반경-테이퍼 소재의 코일스프링이다. 이 논문에서는 주어진 차량조건으로부터 이상적인 스프링 특성곡선을 계산하고 이 곡선을 분할하여 직선의 연결로 근사시켜 분할한 수만큼의 직선적 특성의 스프링으로 직렬 연결되어 있다고 가정하여 이 곡선에 근접된 특성을 가지는 등반경-테이퍼 소재 코일 스프링의 설계방법을 제시하고자 한다.
