【摘要】：随着全球的石油危机、温室效应以及环境污染等问题的日益严重,新能源汽车的研发和应用成为当今世界汽车发展的一大潮流。近年来,在我国政策的鼓励和推动下,国内的纯电动汽车在近两年内得到快速发展。电池成本较高充电时间长、电池使用寿命短以及续驶里程短等都是制约纯电动汽车快速发展的主要因素。而电动客车的正向开发技术也是值得完善和深入研究的问题。本文结合某企业纯电动客车开发的需求,进行了动力参数匹配计算和性能仿真分析的研究。首先,依据纯电动客车基本参数及设计要求,对整车电机动力电池进行了分析计算和选型,对匹配的两速变速器进行了传动比计算。然后,基于动力电池配置对客车前、后轴重及质心位置的影响,采用Catia三维建模的方法,对电池组的空间布置进行分析和优选,以获得良好的制动性能。最后,应用Cruise软件对整车性能进行仿真分析,从而验证仿真所得的性能参数是否达到设计要求。论文从正向设计的角度对某电动客车的开发进行分析计算,提出了基于三维建模和制动性能分析的电池空间布置分析方法,对整车性能进行了仿真分析,并验证了仿真结果的准确性。论文为整车的设计开发提供了技术支持,可缩短开发周期和提升开发效率。
[Abstract]:With the global oil crisis, Greenhouse Effect and environmental pollution and other problems are increasingly serious, the development and application of new energy vehicles has become a major trend of automotive development in the world in recent years. With the encouragement and promotion of our country's policy, domestic pure electric vehicles have developed rapidly in the last two years. The battery cost is high and the charging time is long. Short battery life and short driving mileage are the main factors restricting the rapid development of pure electric vehicles, and the forward development technology of electric passenger cars is also a problem worthy of further study. This paper combines with the pure electricity of a certain enterprise. The development requirements of moving passenger cars. First, according to the basic parameters and design requirements of the pure electric bus, the power battery of the whole vehicle motor was calculated and selected. The transmission ratio of the matching two speed transmission is calculated. Then, based on the influence of the power battery configuration on the front and rear axle load and the center of mass position of the bus, the Catia 3D modeling method is adopted. The space layout of the battery pack is analyzed and optimized to obtain good braking performance. Finally, the performance of the whole vehicle is simulated and analyzed by using Cruise software. In order to verify whether the performance parameters obtained by simulation meet the design requirements. This paper analyzes and calculates the development of an electric bus from the perspective of forward design. A method of battery space layout analysis based on 3D modeling and braking performance analysis is proposed, and the performance of the whole vehicle is simulated and analyzed. The accuracy of the simulation results is verified. The paper provides technical support for the design and development of the whole vehicle, which can shorten the development cycle and improve the development efficiency.
