摘 要: | 对于全域机动车辆而言,高海拔环境起步性能是评价其高原环境适应性和机动性的重要指标。针对多个型号车辆存在的高海拔环境起步困难问题,在系统开展车辆起步过程动力学分析的基础上,从车辆本身所具有的动力和所受外界阻力两个方面对高海拔环境车辆起步性能影响因素进行了深入分析,通过对某军用履带车辆高海拔起步性能的实车试验验证,确定了发动机低速扭矩特性、传动油温、行驶坡度、使用工况是高海拔环境影响车辆起步性能的关键因素,为车辆论证、研制、试验和使用工作的改进和发展提供了依据。

Experimental Study on Starting Performance of Vehicles in High Altitude Environment |

Abstract: | Starting performance in high altitude environment is an important index to evaluate plateau environmental adaptability and mobility for universal motor vehicle. To the starting difficultly of many types of vehicles in high altitude environment, based on systemic the process dynamics analysis of vehicle starting, the influencing factors of starting performance in high altitude environment were analyzed form two aspects--vehicle driving force and resistance force. Through proving test to the starting performance in high altitude environment of a certain tracked vehicle, the key influencing factors are identified including engine torque characteristics at low speed, transmission oil temperature, running slope and operation mode, which provide evidence for demonstration, development, test and operation of vehicles. |
