| Abstract: | In this paper, a two_stage coastdown testing method is presented. It is based on the former methods generally adopted both at home and abroad to determine the air drag coefficient.The results of the two_stage coastdown tests of the vehicle are analysed and compared.It is shown that this testing method can reduce the distance of the testing run way,control the testing error within 5%, simplify the testing conditions and improve the measuring accuracy and the degree of reliability. |
