Maglev vehicle has two kinds of suspension system such as a secondary suspension with air-spring and a primary suspension as electromagnetic suspension which composed of electromagnet, magnet driver, controller and sensors. The interaction between each dynamic component of vehicle and track effects the stability and running performance. To achieve the specified performance of vehicle, many various approaches of research were tried, then as the result of these efforts, the first commercial operating with Maglev will start soon. The bogie for revenue service from 2012 has some significant modifications compared to the previous one, and to verify the changes the half prototype vehicle was manufactured and took the running performance test. In this report, we will introduce the stage of manufacturing and report results of dynamic performance tests to verify new concept of bogie mechanism.

In this paper, the ride comfort of a passenger coach installed with a KT23 type bogie was measured and evaluated through field test in operation routes. The ride comfort level was evaluated and analysed by ISO method and UIC method that were applied generally at railway fields. Particularly three evaluation methods, i.e., a simple method, a full standing method, and a full seating method of UIC513R standard, were fully applied to evaluate the ride quality. Also the vertical and lateral vibration levels on the floor were evaluated by peak-to-peak analysis method.
