高原环境下某装甲车辆空气滤清器性能仿真分析与试验

高原环境特殊，海拔高、气温低、大气压力低，传统重型装甲车辆空气滤清器设计输入为平原地区大气环境与空气密度，为保证高原使用要求，必须预测空气滤清器总成在高原特殊环境下的工作性能。建立了空气滤清器计算模型，构建三维仿真模型并简化，进行仿真计算，预测了空气滤清器在不同环境下的性能趋势。基于理论研究结论，开展了高原实地空气滤清器系统性能测试。对比分析测试结果与仿真结果，得出模型预测结果与试验结果之间误差可控制在20%以内。高原环境特殊，海拔高、气温低、大气压力低，传统重型装甲车辆空气滤清器设计输入为平原地区大气环境与空气密度，为保证高原使用要求，必须预测空气滤清器总成在高原特殊环境下的工作性能。建立了空气滤清器计算模型，构建三维仿真模型并简化，进行仿真计算，预测了空气滤清器在不同环境下的性能趋势。基于理论研究结论，开展了高原实地空气滤清器系统性能测试。对比分析测试结果与仿真结果，得出模型预测结果与试验结果之间误差可控制在20%以内。

The Performance Simulation and Experiment of Air Filter of Armored Vehicle in Plateau Environment

Plateau environment is peculiar, such as high altitude, low temperature, and low atmospheric pressure. The air filters for the traditional heavy armored vehicles are designed according to the atmospheric environment and air density of plain area. In order to ensure that a product meets the use requirements in plateau environment, the working performance of air filter must be predicted. An air filter virtual prototype model of a heavy engineering vehicle is established based on computational fluid dynamics algorithm. The model is optimized to predict the performance of air filter in a different environment. The system performance test of air filter is conducted based on the theoretical research conclusions. The test and simulation results show that the predicted result of virtual model has good consistency with the experimental conclusion.
