Abstract

Through the establishment of stress balance equation and analysis of stress status, de-icing model and brittle fracture model under the conditions of vertical scraping and tilt scraping are presented respectively. According to material strength theory, the thesis analyses necessary external force to eliminate ice layer and its influencing factors, and then gains energy consumption forecast formula of mechanical scraping deicing, which provides the basis for motor selection of ice-scraping mechanism. Conclusion shows that tilt scraping can greatly reduce deicing energy consumption, that the smallest scraping force and energy consumption are obtained with tilt angle of 40°.
