采用理论分析与CFD数值模拟相结合的方法,研究和探讨了进气风室试验装置与进气风管试验装置测试结果产生误差的机理与修正方法.尝试通过理论计算的方法对进气风管与进气风室试验装置间的试验误差进行了修正,将修正后两者的误差控制在工程误差范围内,对风室试验与风管试验结果进行类比分析和修正提供理论参考.%It combines theoretical analysis and CFD numerical simulation approach to research and discuss the mechanism of the intake air chamber device and the intake air duct device test results error and find the correction method. It will try to correct the error between the intake air chamber device and the intake air duct device test through the method of theoretical calculation, and control the error at the range of engineering error. This will provide the theoretical reference for analyse and correct the test result between the intake air chamber device and the intake air duct device.
