Experimental and Numerical Studies on the Lift Force of Moving-Belt System

Abstract:

In order to study moving-belt system’s effect on measurement of lift force, no load test of moving-belt system was carried out by wind tunnel test and numerical simulation and their results were compared. The agreement of lift force results from the wind tunnel test and numerical simulation indicates that the test results and numerical results can be validated each other, and the numerical simulation is feasible. The relationship between moving-belt system and vehicle body shape was studied by using this way. The result shows that for different vehicles, the moving-belt system’s effect on measurement of lift force is almost the same. The △CL is about 0.040 . We can use these relationships to revise the test result of lift force.
