车辆试验舱低气压动态试验系统设计

Design of Low-pressure Area Dynamic Test System for Vehicle Test Cabin

针对车辆发动机在高海拔地区因低气压而性能下降的问题,依托于XX项目需求设计了一套低气压动态试验系统,其可用于模拟高海拔低气压环境和开展车辆低气压动态试验。详细介绍了该试验系统中低气压模拟系统及排烟系统的组成和工艺流程,并进行了抽气速率及抽气量计算。

Aiming at the problem of engine performance degradation of vehicles due to low air pressure in high-altitude areas,a low-pressure dynamic testing system was designed based on the requirements of the XX project,which can be used to simulate high-altitude low-pressure environments,and carry out various dynamic tests of vehicles under low-pressure.The composition and process flow of the low-pressure simulation system and smoke exhaust system were introduced in detail,and the extraction rate and amount were calculated.
