摘要: 为了使转向架参数测试试验能够得到正确合理的数据处理结果, 分析了试验台的工作原理及试验误差产生的原因。采用ActiveX技术, 并利用VB和Matlab进行混合编程, 开发了转向架参数测试台数据处理软件, 对误差进行剔除。分析了定位刚度及回转阻力系数测试数据处理方法, 总结了回转阻力系数计算结果的评判标准。最后运用此软件对CRH5转向架所做参数测试试验的数据进行处理, 以验证软件的可行性。计算结果表明: 各回转阻力系数均小于0.08;在作动器加载频率相同的情况下, 空气弹簧失气工况比充气工况回转阻力系数值大, 在空气弹簧状态相同的情况下, 回转阻力系数随作动器加载频率增大而增大, 因此, 车辆运行速度和空气弹簧状态对车辆曲线通过性能都有影响。Abstract: In order to obtain the correct and reasonable result from bogie parameters test, the principle of bogie parameters test rig and the reason of experimental error were analyzed.An effective and simple data-processed software for the test rig was developed by using VB and Matlab based on ActiveX technology.The error was rejected by the data-processed software.The data-processed method for positioning stiffness and bogie rotational resistance was introduced in detail.The evaluation criteria of bogie rotational resistance was summarized.The feasibility of the software was verified by processing a set of measurement data got from CRH5 bogie parameters test.The result indicates that each bogie rotational resistance is less than 0.08.Bogie rotational resistance in deflated air spring state is bigger than that in the inflated state under the same actuator loading frequency.Under the same air spring condition, bogie rotational resistance increases as actuator loading frequency increases.Therefore, it is shown that vehicle's speed and the conditions of air spring have certain impact on vehicle's curving performance.
