A dynamic load mathematical model for ship's multifunctional cabins was developed using the "black box model"theory. The multifunctional cabins' dynamic loads for a ship navigating in a typical Eurasian route were calculated through this mathematical model. The results show that the air- conditioning load of cabins varies significantly with navigation areas and sailing time. Ventilation load accounts for 51. 92% of the total load,while heat conduction and radiation load only account for 7. 47% and 6. 68%,respectively. For the same navigating area,the maximum load is 2. 648 times of the minimum load for different cabins at the same time. In addition,the impact factors are analyzed by regression analysis method,and 91. 72% of variation of the dynamic load results from the outside temperature change.
