【摘要】 风力发电在电动汽车上的运用,是一种提高电动汽车续驶里程的新型方法,有利于节能环保。本文研究了电动汽车风能利用装置的结构、工作原理和特性,采用实验分析法对风机在不同车速下产生的功率及行驶风阻等问题进行了探讨,验证了将风能利用在电动汽车上的可行性。装置的主要结构是小型风力发电机,利用风能产生电能,实现为蓄电池充电或者直接给用电器供电的功能。行驶过程中的风阻是不可避免的,可以通过合理布置风机位置,如将其置于汽车内部散热器之前,不增加汽车的迎风面积,减小风阻损耗。另外,可应用空气动力学知识对装置进行导流,从而提高装置的使用经济性。如果进一步优化装置后投入生产,这将是新能源汽车发展的一次重大突破,为汽车行业未来的发展奠定了一定的基础。更多还原

【Abstract】 The use of wind generator on electric vehicles is a new method to improve the mileage of electric automobile,which is conducive to energy conservation and environmental protection. This paper studies the structure,the working principle and the characteristics of wind energy utilization device,and discusses the power of the wind generator produced at different speeds and wind resistance by the experiment method,which verifies the feasibility of using wind energy in electric vehicle. The main structure of the device is the small wind turbine,which use wind to generate electricity to supply electricity for the battery or the power device directly. Wind resistance is inevitable in the process of driving,and it does not increase the car’s frontal area by the reasonable arrangement of wind generator position,if placing it in front of the automobile internal radiator. In addition,the aerodynamic knowledge can be used to guide the air flow around the device,so as to improve the use of device efficiency. If the device was further optimized and then put into production,it will be a major break in the development of new energy vehicles,which lays a certain foundation for the development of automobile industry in the future.更多还原
