三轴转向架曲线通过能力分析

Analysis of three-axle bogie curve negotiation capacity

SDD22型机车轴式为C0—C0,中间轴与端轴均采用小轴向间隙的轴箱轴承,为改善机车的曲线通过性能,中间轴采用较小横向刚度的轴箱拉杆。通过计算分析,验证方案的可行性。

Small axial clearance axle-box bearings are used on the intermediate axle and end axle of SDD22Co—Co locomotives to improve curve negotiation performance and the lateral stiffness of intermediate axle-box pull rod is smaller than other's. Calculation and analysis show that the methods are feasible.
