Abstract
A performance estimation of isolation vibration for a container crane is important at initial study stage. We are able to estimate it by the acceleration response spectrum for rocking mode of a container crane direction of trolley drive. However it is important to estimate a response of gantry drive direction. A performance of vibration isolation of gantry dive direction are by a friction response of wheel and rail. This mechanism is non liner system, we can not estimate response easily. In this study, we show the simple estimation method by calculating friction response spectrum.
