실험계획법을 이용한 고속저상대차 최적설계에 관한 연구

초록

Lower Floor Tram(LFT) is a innovative transport system which would complement the environmental consideration, such as reducing emission, and economic aspect, such as operating and maintenance costs retrenchment. In this reasons, introduction of LFT is in the interest of America, Europe, Japan and so on. In Korea, it is required for construction LFT system to ease traffic congestion and provide convenience for transportation vulnerable. In order to this, the advanced technology about tram should be developed and the safety and efficiency should be optimized. In this paper, the structure modeling and dynamic analysis of the LFT is performed, and the performance and riding comfort is evaluated. Then the design variables were optimized by DOE(Design of Experiments) and ANOM(Analysis of Mean).
