文档介绍：机车盘形制动方案设计与分析
摘要
由于高速公路运输、航空运输的飞速发展,铁路运输遇到前所未有的竞争,“高速重载”势在必行,提高机车速度和功率,就必须要有配套精良的制动系统。传统的踏面制动技术已经难以达到设计要求,交流牵引电动机的应用带来的更大空间,这些都使机车采用盘形制动技术成为必要和可能。正是在这一背景下,本文从制动的基本概念说起,介绍了制动力、制动方式、制动距离,然后详细介绍了盘形制动的特点、优缺点以及盘形制动技术的应用,接着介绍了国内外盘形制动的的新技术,最后按牵引电动机的驱动型式分类,对几种类型的转向架,进行了盘形制动技术的方案设计和分析。
盘形制动做为现在世界各国高速列车普遍使用的制动方式,也是今后我国列车制动技术的发展方向之一。我国尚未开发出具有自主产权的带盘形制动的交流传动电力机车,这是一个重要而且迫切问题,需要进一步研究。本文是在目前我国普遍采用的驱动装置的基础上,对采用盘形制动技术进行的变形设计与分析,方案各有特点和不足。

Scheme design and analysis of the otive disk braking
Abstract
Owing to the development expressway transportation and aeronatical transport speedily develops ,and the never existed petition running into in the railway transportation , and " heavy load and high speed " is imperative , otive speed and merit rate are raised , and the brake system that must to have necessaryly excellent . The stepping on face of tradition applies the brake the technology being hard to achieve the design requirement , and exchanges towing the bigger space that the application of electromotor brought , and these all make the otive use the dish structure to move the technology to e necessary with maybe . Being under this background , this text is from the basic concept theory of brake , introduced brake power , brake method and braking distance . Then it detailedly introduced coils structure, the characteristic , the most excellent ing as well as coils the application that the structure moved the technology .Then it introduced the new technology at home and abroad . the drive mould type finally classify according to tows the electromotor .For a few bogie of kind mould , it designed and analyzed the structure movement and the scheme of technology.
One of the brake method that now for each country of world train at a high speed universally used is moved to do to the dish structure , the development direction that also is our country train brake technology from now on . Our country does not develop out exchange transmission electric otive
