The study for the modeling method for creating track data with the irregularity for use as the input to a rail vehicle dynamic analysis

궤도 검측 데이터의 동특성 해석 적용 방법에 관한 연구

The accuracy of the results of the rail vehicle dynamic model is dependent on the realism of the track input to the model. An important part of the track input is the irregularities that exist on actual track. This study presents a modeling method for creating track data with the irregularities for use as the input to VAMPIRE, a rail vehicle dynamic analysis program. The characteristics of the measured track data using the mid chord system has been studied and examined the method to create track data with the measured data to apply in the vehicle dynamic analysis.
