在俄罗斯的铁路网中,出现了由货车转向架铸造零件,特别是侧架,断裂数量不断增加所造成的复杂局面。由于侧架断裂所造成的损失在2011年就达到了几千万卢布。而且其中的90%是俄罗斯铁路公司用于修复线路的上部建筑。分析表明,在过去5年里,侧架的断裂数量呈现不断增长的趋势。由于直接威胁到铁路运行的安全性,这种情况不能不引起政府铁路运输主管当局、俄罗斯铁路公司的领导、机车车辆的所有方和车辆铸件制造商的担忧。 In Russia’s railway network, the complex situation created by the increasing number of fractures in the castings of freight car bogies, particularly side frames, has emerged. The loss due to the breakage of the sideframe reached tens of millions of rubles in 2011. And 90% of them are superstructures used by the Russian Railways to repair the lines. Analysis shows that in the past five years, the number of side frame fractures has shown an increasing trend. Due to the direct threat to the safety of railway operations, this situation can not but lead to concerns of governmental railway transport authorities, leaders of Russian railway companies, all parties to rolling stock and manufacturers of vehicle castings.
