分析了具有交叉支撑的三大件转向架的 4种平面形位偏差对转向架在直线上的运行特性的影响 ,研究了这 4种偏差对转向架轮对偏磨、横向作用力、轮对横向偏移量的关系 ,分析了这 4种偏差与转向架对角线偏差和轴距偏差之间的关系 ,提出了转向架正位检测的主要对象和必要性
The influence of four kinds of plane shape position deviation of bifurcated three-piece bogie on the running characteristics of bogie on straight line is analyzed. The influences of these four kinds of deviation on bogie wheel eccentricity, lateral force, The relationship between the four deviations and the deviation of the bogie diagonal and the wheelbase deviation is analyzed and the main objects and necessity of the bogie positive position detection are put forward
