为了提升我国重载牵引机车转向架的设计水平,采用多刚体动力学软件SIMPACK建立了2B0轴式HXD1型大功率交流传动电力机车动力学模型。通过比较二系悬挂纵向和横向布置方式、二系横向减振器布置位置、车体质心垂向距离和转动惯量的机车动力学性能以及牵引点高度对粘着利用率的影响,结果说明HXD1型大功率交流传动电力机车转向架设计采用二系悬挂横向布置的方式,可以减小二系簧最大横向变形量;二系横向减振器布置在端梁处,可以降低轮轴横向力;牵引杆倾斜布置可以获得较高的粘着利用率;降低车体质心高度对机车曲线通过性能略有利;增加车体长度和转动惯量,可以显著改善机车平稳性指标。
In order to improve the design level of bogie for high power locomotive, the model of HXol type high power AC drive electric locomotive with four axles (i.e. 2B0) has been established with SIMPACK software. With the analysis of secondary suspensions laying on horizontal and vertical direction, secondary lateral dampers arrangement, vertical displacement and moment of inertia to car body mass center and the influence of traction height on adhesion availability, It is shown that the maximum lateral distortion of the second springs can be reduced by proper arrangement of secondary suspensions on the horizontal direction. The lateral wheel interaction forces can be reduced by secondary lateral dampers setting on the end of frame girder. High adhesion availability can be achieved by arranging traction rod with slope. The locomotive behavior through curve can be improved by dropping the height of car body mass center. The riding quality index can be remarkably improved by increasing the length and rotary inertia of car body.
