【摘要】 随着我国铁路五次大提速的进行,机车的运行速度有了较大的提高,但随之而来的是导致部分提速机车的横向动力学性能的恶化。在某些速度下,机车的横向晃动问题比较严重,已经严重影响了机车运行速度的进一步提高。为了满足铁路提速的继续进行以及明年实现部分线路200 km/h的运行,进一步改善机车的横向动力学性能已成为当务之急。本文针对现车考虑,提出通过改进轴箱拉杆的结构,可以有效改善机车的横向平稳性,使该机车满足160 km/h的运用要求。同时,本文通过对提速架悬机车的分析发现,对于牵引电动机采用架悬式悬挂的机车,通过改进目前电动机的刚性悬挂形式,可望在很大程度上改善机车的横向性能。并指出对于160km/h的准高速机车,牵引电动机采用弹性架悬,可以彻底解决提速架悬机车横向性能差的问题。采用牵引电动机采用弹性架悬对机车长期运用中保持良好稳定的动力学性能,改善悬挂部件的工作条件,延长使用寿命非常有利。更多还原

【Abstract】 With the fifth speed-raising of Chinese trains, the traveling velocity of locomotives has considerable raised, but it also leads the deterioration of the lateral dynamic performances of some raising speed locomotives. Under certain velocities, locomotive transverse shakiness is so sever that it prevents locomotive raising speed further. To satisfy railway vehicles to raise speed and to realize the 200km/h operation of some rails next year, it’s pre-requisite to improve locomotive performances. Based on the existing vehicle, this paper offers an efficient project to permit locomotive travel at 160km/h. This paper find that through mend the rigid suspension form of the present traction motor with the locomotive which the traction motor adopted bogie suspension via the analyses of the locomotive adopted bogie suspension, it will improve the lateral performance of the locomotive in quite degree. And point out that for the norm high speed locomotive with the speed of 200km/h, the traction motor adopted elasticity bogie suspension, may settle the problem completely. And this will favor to preserve the locomotive has a good dynamic performance in the long service, improve the work condition of the suspension components and extend the use life.更多还原
