摘　　要：为研发30t大轴重电力机车,研究了推挽式低位牵引杆各项参数对轮重减载率、车体平稳性和脱轨系数等动力学性能的影响。采用多体动力学软件SIMPACK建立2B0机车动力学模型。分析了车辆的直线与曲线通过性能。结果表明直线工况下牵引杆转角对车体垂向平稳性影响较大;曲线工况下随着牵引杆转角的增大导向轮对轮重减载率迅速降低,且变化的斜率随牵引杆长度增加而变大;小半径曲线工况下脱轨系数和轮轨横向力受牵引杆参数影响较小。For the development of 30t large axle-load locomotives, studies the iaflunce of drawbar parameters on dynamic performance such as rate of wheel load reduction, locomotive riding quality and derailment coefficient. Using multi-body dynamics software SIMPACK establishes dynamics model of 2B0 locomotives. Analyzes the straight line and curve negotiation performance of the vehicle.The results show that drawbar angle has greater impact on the locomotive riding quality under the linear conditions. The rate of wheel load reduction decreases rapidly with the increasement of drawbar angle under curve conditions. And the variation of the slope becomes larger with the increasement of the length of the drawbar.Under sharp curve conditions, the derailment coefficient and the wheel-rail lateral force is less affected by the parameter of the drawbar.
