중앙 안내방식의 모노레일 대차 구조와 성능 향상 방안에 관한 연구

The bogie structure of center guided type monorail has been applied to Incheon Wolmi Eunha monorail at first in the world, and aluminum alloy material bogie is first ever introduced in Korea. Since bogie transfers vertical and horizontal loads to the track and guide rail as an essential system, its structure should have enough durability and secure excellent operation performance and ride quality. This study presents a suitable structure for center guided type monorail, a system combination method for bogie operation performance and riding quality, and a solution for better bogie frame durability.
