Vehicle dynamic simulation has been carried out using the coherence of road roughness between left and right wheels. The generated twin tracks with the coherence of road roughness between left and right wheels are in good agreements with the measured coherence relation of left and right wheels. And these tracks reflect well on the roughness characteristics of real roads. Using the generated roads and multibody dynamic simulation program, vehicle dynamic simulation is performed. The vertical and roll motion analysis of a vehicle are carried out using the realistic road profiles with the coherence between left and right wheels and the results are in good agreements with the dynamic characteristics of a vehicle.

This study is analyzed by stress contour of automotive tire at contact on road surface. Maximum equivalent stress as 61200Pa is shown on the lower mid part in case of tire contacted on road surface. As the air pressure of tire increases, maximum total deformation as 5mm is shown on the side part of tire. It can be shown that the side part of tire is unstabilized. There is no load effect on tire at its upper and lower directions. When the moment applied on the side of tire is increased 1.4 times as its value, the value of maximum principal stress is increased 1.4 times. The stress at the tire is in proportion to the moment applied on the its side. The tire tends to incline toward its side by this moment.

본 연구에서는 주행하는 차량에서 관심 도로면의 형상을 재현할 수 있는 시스템을 제안하였다. 차체에 부착된 센서로부터 측정된 신호에 혼입된 차량의 동적 거동 영향을 배제하고 형상 정보를 재현할 수 있는 멀티 센서 시스템을 적용하였고, Lab 실험을 수행하여 센서부에 인가되는 동적 외란에 대해서도 강건한 성능을 검증하였다. 실제차량에 시스템을 구현하여 다양한 도로면에 대한 검증 실험을 수행하였으며 해석적 노면 모델과의 비교를 통하여 그 효용성을 제시하였다.
