Influence of hysteresis on the dynamics of cryogenic LNG composite hoses
conference paper
In order to assess the influence of hysteretic bending behaviour of hoses used for LNG transfer in dynamic environments, a modelling strategy is set up. The modelling allows to include arbitrary internal frictional effects in the hose. After identifying the parameters for various friction models based on measurement results performed on the cryogenic hose, the model is exploited further to study other cases. For hose release events, inclusion of hysteresis accurately seems less importance while for more slowly varying steady-state responses, the way how internal friction in the hose is included may have significant effects.
