摘　　要：针对我国200 km/h客运的需求,作者建立了适于200 km/h速度等级、轴功率1 600 kW的3轴机车转向架平台设计方案。该转向架可满足我国牵引18-20节客车和200 km/h高速客运需求,并可在机车车体和转向架主体结构均保持不变和装配接口不变的条件下,通过转向架内部的局部调整,适应速度160-230 km/h、轴重21-23 t机车的集成需求。3轴转向架结构方案以机车足够的稳定性、高黏着、低磨耗、低轮轨作用力为设计目标,采用交流驱动单元和驱动单元弹性架悬、低位推挽牵引、轮盘制动、磨耗形踏面和柔性二系悬挂等多项先进成熟技术。计算分析表明,该转向架理论上非线性临界速度可达480 km/h,直线运行和曲线通过性能优良。The platform scheme of the 3-axle locomotive bogie with 1 600 kW shaft power was built, according to the requirement for 200 km/h passenger transport in our country. The bogie can meet the demand to draw 18 -20 passenger cars under the 200 km/h high-speed. By means of part adjustment in the bogie with the major structure of the locomotive body and bogie as well as the assembly interface remaining unchanged, the integration needs for the 21-23 t axle load locomotive at the 160-230 km/h speed can be satisfied. The design objectives of the 3-axle bogie structure project are the sufficient hunting stability, high adhesion, less abrasion, and low wheel/rail interaction force. Many items of sophisticated advanced technology are used, for example, the AC drive unit, driving unit flexibly suspended in bogie frames, low-order position push-pull traction, disc braking, worn profile wheel and flexible secondary suspension. The result indicates that the locomotive with the built bogie has the high nonlinear critical velocity at 480 km/h in theory. Its performance on tangent and curved tracks is very good.
