摘要
对空载时移动带系统所产生升力进行实验测量和数值计算,两者得到的升力相差很小,表明所使用的数值计算方法具有可行性,并利用数值计算分析移动带系统与车型的关系.结果表明:对于不同车型,移动带系统给车身升力系数测量带来的影响均在0.040左右.风洞实验可利用该关系对测量结果进行修正.
A void load test of moving-belt system was carried out respectively by wind tunnel test and numerical simulation and the results were compared. The comparison result indicates that the test results agree well with the numerical results, which proves the numerical simulation is feasible. The relationship between the moving-belt system and the vehicle body shape was also studied by numerical simulation. The result shows that the effects of the moving-belt systems of different vehicles on the measurement of lift force are almost the same, and the ACL is about 0. 040. The relationship can be adopted to modify the test result of lift force.
