Selection Of The Power-train For A SUV Model Basing On The Power Performance And Fuel Economy Simulation Calculation

In recent years, the domestic small SUV market develops rapidly, and the miniaturization trend of SUV is increasingly obvious. A is a best-selling SUV products of a car company. The car company decides to develop A’s replacement models. The Power-train, which determining the car’s function of power and economy, is the core component of the vehicle. The power performance and fuel economy of car are the most basic performance of the vehicle, regarded as a hot market and consumer’s attention, which is a prerequisite for the development of any car. The selection of Power-train even directly affects the development project progress and success of A’s replacement model cars, which has the strategic importance for the company.In order to ensure the successful completion of the development of the SUV model, the essay develops the selection of the Power-train from the following aspects:① Taking advantage of the simulation model of CRUISE, and calculating the power performance and fuel economy index of the Power-train solutions. Finishing the primary selection of Power-train for the SUV Vehicle basing on the power performance and fuel economy.② Making use of the 3D modeling software--CATIA to analyze the layout of engine compartment, and judging the feasibility and risk level of general layout. Analyzing the cost of optional Power-train, and assessing the feasibility and risk level of the cost.③ According to the result of the power performance and fuel economy, the analysis of layout and cost, determining the optimal Power-train scheme to finishing the selection of the Power-train for the SUV model.
