减少轴重转移是充分发挥机车牵引能力的根本措施之一。随着大功率货运机车的发展,近20年来国内外对牵引力作用下转向架式机车的轴重转移进行了大量的理论分析和实验研究,明确了非0位最佳牵引点的概念以及如何达到最佳轴重转移的转向架结构参数匹配问题,为机车设计提供了理论依据。但是,国内 Reducing axle weight transfer is one of the fundamental measures to give full play to locomotive traction ability. With the development of high-power freight locomotives, a great deal of theoretical analysis and experimental research have been done on the axle load transfer of bogie locomotives under the traction force both at home and abroad in the recent 20 years. The concept of the best traction point other than 0 and how to achieve The optimal axle weight transfer bogie structure parameter matching problem provides a theoretical basis for locomotive design. However, domestic
