시뮬레이션을 통한 K-AGT 대차 성능 향상을 위한 동특성 연구

초록

K-AGT Bogie has a rubber wheels and side guide. Side guide type has a many merits but occur a vibration and friction through contact between guide rail and guide wheel. Present max speed of operation is 60km/h. We start study for improved a max speed of operation to 70km/h. Most of point that decreased comport is vibration through the guide contact. So we make the improved guide part of two types (Spring and Rubber Type). In this study, we modeling with CATIA and conducted a dynamic analysis with ADAMS. Finally, we optimized guide rail spring with simulation using the ADAMS
