승차감 시뮬레이션을 위한 좌우 불규칙 노면 형상 생성

A double track random road profile generation for vehicle ride comfort simulation has been carried out using the filtering method. The filtering method is composed of two filter systems. One is the road filter that generates the single track road PSD shape proposed by ISO, MIRA, and Wong. The other is the correlation filter that makes the relation between the coherence of the parallel tracks of left and right wheel of a vehicle. Generated double track road profiles using the proposed method are in good agreements with the target road PSD shape and the measured coherence relation.
