摘要
安全可靠性、平稳性和舒适性的研究是目前高速机车运行所面临的重大课题。油压减振器作为机车车辆走行机构的重要组成部件之一,其性能优劣直接影响到机车车辆运行的稳定性和安全性,先进、可靠的油压减振器试验台是油压减振器出厂检验及维护保养的关键设备。
本文首先针对机车油压减振器及其检测技术的国内外现状,简要分析了我国目前铁路上几种常见的油压减振器的原理、作用、性能特点等。同时对国外和国内机车油压减振器试验台的结构及优、缺点进行了详细的分析,结合我国的实际现状,提出了低成本微机控制油压减振器试验台的方案。
(1)、本试验台是根据最新铁标《机车车辆油压减振器试验台技术条件》和《机车车辆油压减振器技术条件》研制的。可分别对垂向和横向(包括抗蛇行)减振器进行测试,适用于国内已有的各种型号的机车减振器的试验,同时还可满足欧洲油压减振器试验之用。
(2)、试验台采用齿轮变速加无级变频调速,微机控制及闭环转速控制技术,利用正弦激励振动实现油压减震器的各项性能测试。在满足技术要求的前提下,相比其他测试方案,生产成本更低。同时因采用精密滑轨及同步传动技术使设备的振动更小,噪音更低。
(3)、以 windows 操作系统作为开发平台,借鉴 Microsoft Windows 图形用户界面的许多先进特性和设计思想,利用 windows 系统的多任务管理功能,采用面向对象的可视化编程的 的语言编制的测试系统软件,使整个测试系统的人机界面友好,实现了测量、控制、参数设定、记录和数据处理的全自动化,使现场操作更便捷。

ABSTRACT
The development of Security , reliability, smooth fort of high-speed otive is currently a major issue. Oil damper,as the ponent of otive Running Gear, its performance directly impact the stability and safety of otive. Advanced, reliable Test Platform of oil damper is the key equipment for hydraulic test ,inspection and maintenance of oil on internal and international researches about the test technology of oil damper, this paper first briefly analysis the principles ,functions, characteristics and dynamics of mon oil damper on current railway. At the same time, the structure and the advantages and disadvantages of foreign and domestic otive oil damper test platform has been analyzed in the paper. Combined with the status of our country, a program has been proposed of a low-puter controlled oil damper test platform.
This platform is developed basing on the latest Taiwan Railway superscript"rolling stock oil damper experimental bench technology" and " otive and Vehicle Structure oil damper technology". It can test the vertical and horizontal (including anti-hunting) dampers, and apply to the test of the various models of the shock absorber,while also m
