복합소재대차와 기존 대차의 곡선부 성능 비교

초록

In this study, curving performance between a composite bogie and a conventional bogie was evaluated and compared. For this goal, running test was performed on a curved rail with radius of 400mm using a motorized vehicle and a lateral force was measured. From the test results, the lateral force of the composite bogie, that is 29% lighter than the conventional bogie, was 33% lower than the conventional one. In conclusion, it can be ensured that the composite bogie without primary suspensions has better curving performance compared with the conventional one.
