| Abstract: | Through the wind resistance of pre-research vehicle subsystems,such as weight,tire rolling resistance coefficient of target parameters is analyzed,combining with the reference models slide way and drum coasting test data,using the theory of automobile related principle,put forward three kinds of methods for calculating the pre-research models the theory of sliding resistance,used in the early stage of the simulation and emission test touch bottom. |
