| 摘要： | Laboratory tests were performed with a hydraulic ice-cutting rig to determine the effects of the geometry of the cutting edge of a snow plow blade on the force required to remove ice from a highway pavement surface. Test results indicated that the most important parameter was the clearance angle, and the associated flat width. Using this information, a prototype cutting edge was designed and fabricated for field testing during the winter of 1991-92. Three different cutting edges were tested: the prototype cutting edge, and two commercially available cutting edges. The prototype cutting edge was shown to be clearly superior to the other two edges, cutting more ice with less downforce and thus resulting in greater vehicle control. |
