Design of the Impact Absorber used for a Shuttle Car for LMTT with respect to the Drop Height of a Container

컨테이너의 낙하높이에 따른 LMTT 용 Shuttle Car 의 충격흡수기 설계

LMTT (Linear Motor-based Transfer Technology) is horizontal transfer system in the maritime container terminal for the port automation. The system is driven by PMLSM (Permanent Magnetic Linear Synchronous Motor) that is consists of stator modules on the rail and shuttle car. This paper investigates the effect of the drop height of container on impact reaction force of the Impact Absorber (IA) in shuttle car for LMTT. The results of this investigation are obtained from detailed finite element analysis for various parameters, such as the spring coefficient, the drop height of container.
