Abstract
In order to improve the operation of existing ship bridge simulator training function,adding ice sailing ship maneuvering simulator training platform for ice sailing ship characteristics,the use of micro-element method ice sailing ship dynamic mathematical model,and the model is loaded into the marine handling simulator platform development. Element method using micro-contact part of the ship and ice analysis and study,drawn ship longitudinal,transverse and vertical directions three ice impact velocity of the ship to arrive at the ship in all directions by the impact of the size of the ice and add them to the separation-type ship maneuvering mathematical model. Performed by a given ship cycle simulation experiment results show that the establishment of a ship sailing in ice sports mathematical model error less than 20%,can be applied to existing development and application among ship bridge simulator.
