대심도 터널 피난관제 주행로봇의 궤도레일 최적설계

초록

In this paper, design optimization was carried out for the track rail of an evacuation guidance robot system to be operated in a deep railway tunnel. Deep railway tunnels are becoming bigger and bigger, and since it is necessary to evacuate through a tunnel in case of a fire, the need for an evacuation guidance robot capable of real-time evacuation control is increasing. For the stable operation of the evacuation guidance robot system, it is necessary to review the stability of the track rail. The main geometric parameters of the support for the mounting of the track rail inside the tunnel were derived, and the geometric parameters of the stress and natural frequency were studied. Based on this, the optimal cross-sectional shape of the track rail was obtained in terms of driving stability by applying the topology optimization technique. In addition, the optimal track rail shape to secure running stability was obtained by examining the width dimension of the cross-sectional shape of the track rail support. The results of this study could be applied for the detailed design of a track rail while considering the running stability aspect in the design process of an evacuation guidance robot.
