摘要
采用黑箱模型理论建立了船舶多功能舱室动态负荷数学模型,经分析求解,获得了某典型欧亚远洋航线上的船舶动态负荷变化规律.结果表明:船舶空调负荷随航区、航行时刻发生显著变化,通风负荷占总负荷的51.92%,而舱壁导热、辐射负荷仅分别占总负荷的7.47%,6.68%;同一航区同一时刻,各功能舱室负荷最大值是最小值的2.684倍;此外,运用回归分析知,可变舱室负荷的91.72%受室外温度变化的影响.
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 va- ries 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 navi- gating area, the maximum load is 2. 648 times of the minimum load for different cabins at the same time. In ad- dition, the impact factors are analyzed by regression analysis method, and 91.72% of variation of the dynamic load results from the outside temperature change.
