| 摘 要： | 为研究地形坡度对车辆越野机动时间的影响,预测和估计车辆通行时间,采用了数字高程模型(Digital Elevation Model,DEM)来模拟复杂的地貌形态。采用了移动窗口法计算了DEM格网单元的坡度,建立数学模型研究了地貌对车辆越野机动的速度影响系数,包括两方面:坡度引起路线延长和坡度影响车辆自身速度。通过实例分析计算了车辆通行时间,该方法为准确研究车辆越野机动通行时间提供了理论依据和参考。

| Abstract: | In order to study the effect of slope on Off-road maneuver of the vehicle,to predict and evaluate the vehicle's moving time,Digital Elevation Model (DEM) is used to simulate the complex relief structure.In this paper,we adopt the moving window method to calculate the slope of DEM grid unit,and present the mathematical model to research the deceleration coefficient of relief to Off-road maneuver of the vehicle,which includes two parts,the extended road caused by the slope and the speed of the vehicle.Experimental results provide theoretical reference for researching the vehicle's moving time on Off-road maneuver. |
