首先对电机轴悬式（滚动抱轴承）和电机架悬式（轮对空心轴）结构进行了简要分析，然后分别根据这两种方案的设计计算结果，客观地分析了这两种转向架准高速运行时的主要性能及其对线路的动力作用差异，最后以试验和运用结果为依据，就我国铁路在既有线路上实行旅客列车提速所涉及到的机车转向架结构选型问题发表了一些看法和建议。
Firstly, the structure of the motor shaft suspension (rolling bearing) and the motor frame suspension (wheelset hollow shaft) are briefly analyzed. Then according to the design and calculation results of the two schemes, the two kinds of bogie standards are objectively analyzed The main performance during high-speed operation and the difference of dynamic effect on the line. Finally, based on the test and application results, some opinions on the selection of the locomotive bogie structure involved in the acceleration of passenger trains on the existing lines in our country And advice.
