YWXZ º º t rzyywxzhy`` k Ž Ÿo r m ƒ 2 Flanged uide Wheels Tram Review Compliance Criteria of the Road Structure Ò ã ä ã ä ãã Kwang-Suk Seo *, Seung-Il Lee *, Oak-Young Song * * "CTUSBDUTram of the city public transport increased interest in the review of criteria for the installation of the tram is required. In particular, among the tram guide wheel of 2flanges in the case of using the existing road structure and compliance review is required. The reason to build a tram on the road, the road and tram operations can be performed efficiently. Thus, the tram guide wheel of 2 flanges guide the dynamic analysis of the vehicle through the road structure and road conditions, according to the structure of the service is the speed limit should be considered. In this regard, this study guide wheel of 2 flanges according to the characteristics of speed and vibration analysis through the single track road structure of driving conditions is intended to examine the suitability.
