动车总体结构设计分析.doc

摘 要 由于铁道运输具有速度快、运量大、耗能低、污染轻等诸多优点，因此一直都是世界各国现代化交通运输体系中最为重要的运输手段，在国民经济的发展过程中起着主要的作用，为了促进经济的发展，一直通过提升本国轨道交通技术装备现代化水平，不断提高机车车辆的运行速度。在这方面要解决高速轮轨关系、高速转向架、大功率牵引、制动控制、可靠性和安全性等方面的设计理论和技术。 本次设计为动车总体的设计分析。根据动车的特点，设计的动车主要内容包括：不锈钢车体，最大限度地实现车体轻量化,并对车体内外要求设计及其校核；高速转向架是列车高速运行最重要的基础条件之一，主要考虑了轻量化和耐腐蚀设计 Abstract As Railway transport with high speed, large capacity, low energy consumption, light pollution, and many other advantages, has been one of the most important means of transport in the world of modern transportation system, and plays a major role in the development process of the national economy. In order to hasten the speed of economic development, we always have to up grade technology of rail transportation , modernization level of equipment and constantly improve the operating speed of locomotives and rolling stock. In this fieil should pay our attentions to hasten the ability of design theory and technology of high-speed of wheel-track, high-speed of bogies, traction power, brake control, reliability and security. This layout is about analysis to the overall design of car dynamic. According to the characteristics of car dynamic, this design mainly includes: development of stainless steel body; to achieve the maximum body lightweight and high-speed train bogies’ operation of putting down the vibration and noise; to ensure safety and reliability of strength ;the choice of high-speed train traction system to provide high-speed train traction and provide point-force; Choose the train speed continuously improve the circumstances, it is also necessary in a set time and distance from the parking, relying on the traditional method of braking has not solve the problem of high-speed train braking, braking and braking system will have a direct bearing on the size of capacity Trains can run to safety.
