Title The overall design of an electric vehicle
Abstract
In recent years, the rapid development of the world's automobile industry and automobile production growing number of, the energy crisis and environmental pollution is increasingly serious. Electric vehicles will become the main direction of the future development of the automotive industry. In this paper, the design of an electric car, first discusses the general design principles and overall design, according to the usage conditions to compliance with the relevant provisions of the general parameters of electric vehicles, to achieve steering, suspension, braking, body line model selection and placement. Then based on the comparison of various characteristics of the motor vehicle battery , select battery and the motor , and use the knowledge of the motor to achieve the requirements of battery, matching the design parameters of the drive train and motor. In this thesis, I use the AutoCAD to draw the two-dimensional map of each part of the electric car, and I also use CATIA to model the electric vehicles . Includes vehicle, motor, battery, transmission and other models, and also I research and analysis it.
