  • As motorcycles are getting more widely used recently, motorcycle accidents are gradually increased every year. Although most accidents are caused by human factors, the importance of motor vehicle safety standards cannot be underestimated indeed. A variety of regulations related to motorcycle safety have been issued in many countries such as EU, U.S., and Australia, etc. In order to harmonize the international safety standards, it is necessary to develop or enhance the Korean Motor Vehicle Safety Standards (KMVSS) for motorcycles. In this study, motorcycle safety standards for an exterior rear-view mirror and a tire are investigated. Actual test procedures are expected in sequential studies according to the results provided herein. Also, the findings in this paper can be utilized to ensure the KMVSS for a safer driving.

  • In order to satisfy customer's requirements of ride comfort and high performance, it is necessary for designers to fully understand vehicle aerodynamics and wind noise of newly produced cars because characteristics of flow and wind noise are heavily dependent on each other. In this study numerical and experimental study have been carried out to analyse the effect of flow characteristics at around of rear view mirror on wind noise and soiling on the front S/W. As a result, it's found that the spiral flow mear the front pillar is weakened and spreaded because rear view mirror obstructs the flow. It is also shown that there is abrupt change of gradient of separa- tion line, separation area, intensity of spiral flow and turbulent kinetic energy with varying shape of neck and housing of rear view mirror.
