摘 要：经过数百年的发展，汽车的安全与节能性已经成为其设计的重要内容。而在汽车的设计中，汽车的基体车架是用来支撑、连接汽车的各总成，使各总成保持相对正确的位置，并承受汽车内外的各种载荷。目前，针对节能车车架设计中的节约电能消耗和提高燃油经济性能的问题，通过对车架的设计结构进行分析简化，利用SolidWorks软件对车架结构进行设计建模和强度分析，基于上述结果，分析得到车辆的几个主要组成系统对赛车电能消耗特性的影响规律。然后以车架轻量化和车身空气阻力最小化为设计目标使得节能车车架结构达到一定的优化，从而实现减轻车辆的电能消耗，具有一定的理论和实践意义。

Abstract：After hundreds of years of development， the safety and energy saving of automobiles has become an important part of its design. In the design of automobiles， the base frame of the automobile is used to support and connect the various assemblies of the automobile， so that each assembly maintains a relatively correct position and bears various loads inside and outside the automobile. At present， in view of the problems of saving power consumption and improving fuel economy performance in the design of energy-saving vehicle frames， the design structure of the frame is analyzed and simplified， and the SolidWorks software is used to design modeling and strength analysis of the frame structure. Based on the above results the article analyzes the influence law of several main components of the vehicle on the power consumption characteristics of the racing car. Then， with the design goal of lightweight frame and minimization of body air resistance， the frame structure of energy-saving vehicle can be optimized to a certain extent， so as to reduce the power consumption of the vehicle， which has certain theoretical and practical significance.

汽车市场的不断扩大，造成当今国内外汽车市场的竞争日益激烈，使得汽车产品的研发周期不断的缩减，由原来的几十年到如今的几年甚至十几个月[1]。使汽车的各向性能面对了更大更多的挑战。

除此之外，随着汽车行业的快速的发展，当前全球能源危机日益凸显[2]，随之而来的便是大量使用汽车所造成的环境污染。因此汽车的节能减排已经成为了不可忽视的问题，亟待解决。而本文所要研究的内容就是基于上述所出现的问题，通过SolidWorks软件对车架结构进行结构设计和分析处理，以车架轻量化和车身空气阻力最小化为设计目标优化节能车车架结构，从而实现减轻车辆的电能消耗。……
