Dynamic Analysis of Variable-Gauge Wheelset

궤간가변대차용 윤축시스템의 동역학적 해석

The variable-gauge wheelset drives on the variable railways. It doesn't need to replace or move the carriages to another bogie parts. This paper is for dynamic analysis of the variable-gauge wheel set. 3D-Virtual Mock-up. program was developed to verify the operating mechanism and understand dynamic characteristics for German RAFIL- V variable-gauge wheel set. When the system is going through the width-variable railway, its safety depends on the stiffness and velocity. So the numerical and contact model of this system were developed. This solution is useful to analyze dynamic characteristics for variable-gauge wheelset.
