在大型的工程机械当中,轮式的车辆和履带式的车辆都被广泛应用。履带车辆具有较好的通过性,而轮式车辆机动性较好。这两种车辆在工作行驶过程中都会受到外部的行驶阻力,其外部行驶阻力的产生机理有所差别,通过对比这两种车辆的外部行驶阻力,为工程机械的选择提供一定的依据。 Among large construction machines, wheeled vehicles and tracked vehicles are widely used. Tracked vehicles have better passability, while wheeled vehicles have better maneuverability. Both of these vehicles are subject to external driving resistance during their work driving, and their external driving resistances have different generating mechanisms. By comparing the external running resistance of these two vehicles, the two kinds of vehicles can provide some basis for the selection of construction machinery.
