摘　　要：通过对汽车模型风洞试验腹部支架干扰的分析，提出了测量支架干扰的“空装模型法”。四种不同的汽车模型支架干扰测试结果表明，气动阻力系数的支架干扰量ΔＣＤ可占修正后气动阻力系数ＣＤ的１０％～３０％。A 'Separating Model and Support (SMS) method' for measuring support interference is proposed according to the analysis of the support interference for vehicle model wind tunnel tests in this paper. The support interference tests using SMS method for different vehicle models shown that the support interference of drag coefficient  Δ C D is 10 to 30 percent of drag coefficient C D in general conditions.
