The effect of the drop height of a container on impact reaction force of the impact absorbing system in shuttle car for the LMTT

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 consists of stator modules on the rail and the shuttle car. The impact absorbing system that consists of compression spring is located between the frame and the stator module in shuttle car for the LMTT. We investigate the effect of the drop height of container on impact reaction force of the impact absorbing system (IAS) 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.
