The invention discloses a steering error calibration control method applied to a multi-connecting-rod type active radial bogie, which comprises the following processes: when a train starts to drive into a turning track, a central controller sends a steering instruction to a servo electric push rod, so that the servo electric push rod drives a multi-connecting-rod transmission mechanism to act; the wheel sets are driven to deflect with the center lines of the two wheel sets and the circle center of the track as the radial steering center, the central controller collects the actual deflection angle of the wheel sets in real time through the axle box displacement sensor, and real-time compensation adjustment is conducted according to the deviation between the actual deflection angle and the expected deflection angle. According to the method, the transformation cost of the bogie is greatly reduced, meanwhile, the abrasion of wheel rails is effectively reduced, the abrasion of wheel pairs is reduced, the accuracy and real-time performance of active steering are improved, meanwhile, the stability of train operation is guaranteed, and the accuracy and reliability of the steering function of the active radial bogie are guaranteed.
本发明公开了一种应用于多连杆式主动径向转向架的转向误差校准控制方法,包括以下过程:当列车开始驶入转弯轨道时,中央控制器给伺服电推杆发出转向指令,使伺服电推杆驱动多连杆传动机构动作,带动轮对以两轮对中线和轨道圆心为径向转向中心发生偏转,中央控制器通过轴箱位移传感器实时采集轮对的实际偏转角度,并根据实际偏转角度和预期偏转角度的偏差进行实时补偿调整。本发明在大幅降低转向架改造成本的同时有效减少轮轨的磨耗,降低轮对的磨损,提高主动转向的精度与实时性,同时保证列车运行的稳定性,保障主动径向转向架转向功能的精准性和可靠性。
