The matching design and engineering computation of power performance and fuel economy for economical automobiles
ABSTRACT
We must grasp the relationship between the vehicle dynamic and fuel economy in automobiles at the design stage, then we should evaluate the vehicle dynamic and fuel economy. According to the results, optimization is proposed. The relationship provides the theories calculation of automobile powertrain system and the excogitation of other related component parts. The main content of this excogitation is to determine the parameters of economy car and to match the vehicle power performance and fuel economy. The car assembly drawings and parts diagram were designed by the software of CATIA.
The design calculation of vehicle parameter including wheelbase, the highest vehicle speed, the load of front and rear axle, steering form are confirmed by limits and stipulation. All of these can meet the requirements of relevant national standards.
Determine the parameters of economy car and to match the vehicle power performance and fuel economy at last.
