摘要
根据城市轨道交通运行站距短而要求旅行速度较高的特点,分析了城市轨道交通车辆各项牵引参数;指出起动加速度的选择对轴功率和旅行速度都有着直接的影响,起动加速度大于0.9m/s^2后,应慎重考虑,在保证得到规定旅行速度的同时,避免不必要地增加轴功率,以降低车辆和其他设施造价.
Urban mass transt requires a higher speed at shorter intervals between stations. Through an analysis of the traction parameters of urban mass rolling stocks, the author argues that the selection of motive acceleration is a decisive factor to influence the axle power and the train speed. When the motive speed exceeds 0.9 m/s2, it shall be very caustious to avoid increasing the extra axle power, so as to lower the cost of the rolling stocks and other installations, and at the same time to ensure the fixed traveling speed.
