다기능성을 갖는 철도 차량용 승차감 측정시스템 개발

초록

Recently, the “ride comfort” problem becomes increasingly important because of today's needs for train speedup. The concept of term “ride comfort” is equivocal. Generally it is defined as the vehicle vibration. There are many studies on evaluation method of ride comfort for railway. But each of them recommends the different assessment method and the different guidance. In general, the evaluation methods defined in the standards, such as ISO 2631 and UIC 513R, and Ride Index suggested by Sperling, have been used in the railroad. But, only one or two methods of these can be evaluated by using the commercial ride comfort measuring system. Therefore, it is necessary to develop the new ride comfort measuring system for railway with multi-function. In this paper, the generalization of “ride comfort” and the design and verification of new ride comfort measuring system for railway with multi-function have been described and the application examples has been introduced.
