本文对我国现行曲线距轨加宽标准进行了理论分析,指出它脫离运营实际,而采用计算数据又不符合我国现有车辆情况,加宽起始半径和加宽值都偏大。提出在理论上比较切合实际的计算方法是车辆按力学自由內接条件计算;机车和少数固定轴距大的车辆,按最小运营半径条件检算,制订我国的曲线轨距加宽新标准。新标准比现行标准缩小了曲线轨距加宽起始半径,能使我国主要干线曲、直线轨距基本一致,简化轨道设备,有利于铺设和养护维修工作。
In this paper, the theoretical analysis of the existing curvilinear widening of curvilinear curve in our country is made, and it is pointed out that it deviates from the actual operation. However, the calculated data do not accord with the existing vehicle in our country. It is put forward that the more realistic calculation method in theory is that the vehicles are calculated according to mechanics free internal conditions. Locomotives and a few small vehicles with fixed wheelbase are calculated according to the minimum operating radius condition, and a new standard of curve gauge widening in our country is formulated. The new standard narrows the starting radius of the curve gauge wider than the current standard, which can basically make the curvature and linear gauge of main trunk lines in our country simpler, which is good for the laying and maintenance of maintenance work.
