摘　　要：在寒冷环境下甲板机械很容易受到冰冻的危害,为了保证机械能够进行安全的作业,进行除冰的研究十分必要。利用热风对甲板机械进行除冰的方案是可行的,除冰的效率取决于热风的温度、速度和出风角度。通过分析各参数对除冰的贡献率,发现出风角垂直冰面时除冰效率最高;提高风速和温度对除冰效率有一定帮助,但能量的利用率会降低,经济性较差;增加风速比增加温度除冰的经济性好。The deck machinery is in danger of freezing hazard in the cold environment. To ensure safety in operation, it＇s necessary to do deicing research. It＇s feasible to deice for the deck machinery by hot air. Deicing efficiency depends on temperature, speed, and air-out angle of the hot air. Through analysis of the contribution of various parameters to deicing, it＇s found that the deicing efficiency is the highest when air-ont angle is vertical to the ice surface; increasing both the airspeed and temperature is helpful to improve the deicing efficiency, but the energy utilization can be reduced and the economical efficiency is also inferior; increasing the air speed shows better economical efficiency for deicing than temperature rise.
