低气压环境模拟系统设计研究

Research on Low Pressure Environment Simulation System Design

目的-车辆在高原地区行驶时,由于气压低,空气稀薄,对车辆动力性能会带来极大影响。空气密度的降低会使发动机功率下降,同时对车辆辅助系统的性能产生显著影响。方法-通过控制试验室内真空环境,达到高海拔模拟的需求。结果利用该方法,预期可以在室内完成高原试验。结论-本文阐述了整车低气压模拟试验系统设计。

The depression and rarefied air will have great influence on dynamic performance of vehicles in plateau areas.The reduction of air density can make engine power decreased,and have significant impact on the performance of vehicle auxiliary system synchronously.By controlling the vacuum environment in laboratory which achieved the high altitude simulation demands,the high altitude test can be carried out in laboratory.This paper describes the design of vehicle low pressure simulation test system.
