Abstract

This paper concerns about study on the kinematic characteristic of coupling device in deep-seabed mining system. This coupling device connects between buffer system and transfer tube. The motion of buffer system, transfer tube, flexible pipe and mining robot are affected by the coupling device. So coupling device should be considered major when this device is designed. Therefore, we find stable kinematic device and will apply to design coupling device throw this study. The kinematic characteristic of coupling device is analyzed by multi-body dynamics simulation method and finite element method. The dynamic analysis model has been built in the commercial software of DAFUL. FSI(fluid structure interaction) method is applied to build deep-seabed environment. Hydrodynamic force and moment are applied in dynamic model for FSI method. Loads and deformation of flexible pipe is estimated for analysis results of kinematic characteristic.e and mining robot are affected by the coupling device.
