摘　　要：针对国内货运快速重载化发展所产生的车辆系统动力学问题,基于自导向径向转向架和迫导向径向转向架的设计原理,参照Scheffel自导向径向转向架,在转K6型交叉支撑转向架的基础上,对自导向径向转向架和迫导向径向转向架进行结构设计,并将这三种低动力转向架的曲线通过性能进行对比分析.结果表明,所设计的迫导向径向转向架相比自导向径向转向架和转K6型交叉支撑转向架在轮对冲角、轮轨横向力、脱轨系数、整车磨耗功率方面具有性能优越性,并且具有良好的蛇行稳定性,说明对迫导向径向转向架的结构设计是合理的.For the dynamic problems of fast and heavy load domestic frei ture design of the self steering radial bogie and the forced steering bogie t vehicle system arising with struc- conducted based on the frame de- sign principle of the self steering radial bogie and the forced steering radial bogie, according to the Scheffel ra- dial bogie, on the basis of K6 cross brace bogie. The curving of three low dynamic bogie is compared through performance. The experiment results indicate that the design of the force steering radial bogie compared with radial bogie and K6 bogie has a good hunting stability and superiority performance on wheel angle, wheel/rail lateral force, derailment coefficient and the vehicle fricition power, which proves the rationality of the force steering radial bogie structural design.
