全地形林火地面巡护扑救车越障性研究

Study on Off-road Crossing Performance of All Terrain Vehicles for Patrolling and Fighting Forest Fires

介绍了从美国引进的全地形林火地面巡护扑救车的用途及性能,建立了其跨越障碍物时的力学模型图、车辆越过障碍物时的力学关系以及越障条件,分析计算出在不同附着条件下该车前轮越障高度随车辆重心位置变化的曲线,对研究该车辆的装备、装载重量以及装载位置提供了重要依据。

The functions and performances of all terrain vehicles for ground patrolling and fighting forestry fire from USA is introduced.Its mechanical model,mechanical relations and necessary conditions when crossing obstacles have been established.Analytical calculations show that the curve that obstacle clearing capacity of the front wheels under different conditions change with the position of center of gravity of vehicles can supply important basis for the study of the weight and the position of its equipment and loads.
