Abstract:

This paper introduces the characteristics and the process in NRC wind tunnel test of a heavy-duty truck in Canada. Based on some information in the test report and the calibration method for closed wind tunnels， the correction method of NRC wind tunnel is deduced and the correction formula is obtained. The original data are processed with the derived correction formula， and the results are in good agreement with the test report， which proves the validity of the derived formula， provides reference for the aerodynamic test of heavy trucks in the closed test section wind tunnel.

Key words:heavy-duty truck;vehicle aerodynamic;vehicle wind tunnel;correction;non-continuous body
