Rail Vehicle Curve Negotiation Bump-Stop Active Vibration Control Centering Control Experiment with Scaled Model Speed-Up Tilting Vehicle 乗り心地

项目摘要

In this study, addition of centering control to the active suspension of rail vehicles was examined for preventing the lateral bump/stop caused by the high-speed curve negotiation.Firstly, numerical simulation showed that the cooperative work was possible for vibration control and centering one using an identical actuator in the secondary suspension. Here, as the mounting height of actuator, almost the central position of secondary spring was effective for the centering control. The largest control force in the running at 45 km/h higher than the regulation speed was greatly surpassed the one needed for only the vibration control. This indicates that it is necessary to employ hydraulic or electromechanical actuators rather than pneumatic ones for cooperative work of the two controls.Secondly, experiments with a scaled half vehicle model were carried out inclining the experimental apparatus by the angle of 7 degrees that corresponded to an excess centrifugal acceleration. In the experime … More nt with the centering control, the lateral bump/stop in the secondary suspension was prevented in all the examined frequency range. The results showed the possibility of improving the ride comfort with the cooperative control, although the effects of the two controls are in a trade-off relation.Thirdly, the effect of the cooperative control was improved by applying H^∞ control law. Considering the trade-off relation of both controls, a weighting function was proposed for the controller design, and its effectiveness was confirmed under the condition with random excitation from actual track irregularity and equivalent excess centrifugal acceleration.In the fourth, the cooperative control using observable states on the tilting car was examined by numerical simulation and it was confirmed that the effect could be kept with observed accelerations.Finally, this study established a control mechanism and its controller design method for the active suspension of rail vehicles running on curved tracks at high speeds. In the future, it is necessary to confirm the effect using practical vehicles, and it is indispensable for practical use to secure the reliability of control system in both the software and the hardware.

本文研究了在轨道车辆主动悬架中加入对中控制，以防止高速曲线通过引起的横向颠簸/停车问题。首先，数值模拟表明，在二次悬挂中采用相同的作动器进行振动控制和对中控制是可行的。这里，作为执行器的安装高度，几乎以二次弹簧的中心位置作为对中控制的有效位置。在高于规定速度45公里/小时的运行中，最大控制力大大超过了仅进行振动控制所需的控制力。其次，在半车模型上进行了实验，实验装置倾斜7度，相当于离心力过大时的加速度。在实验…中在中心控制下，在所检测的所有频率范围内，二次悬架中的横向碰撞/停止都得到了防止。结果表明，虽然两种控制的效果是权衡的，但协同控制改善乘坐舒适性是可能的。再次，应用H^∞控制律改善了协同控制的效果。考虑到两种控制的权衡关系，提出了一种权函数用于控制器设计，并在实际轨道不平顺和等效超额离心力随机激励条件下验证了其有效性；第四，通过数值仿真验证了摆式车辆可观测状态协同控制的有效性，证实了在观测加速度的作用下可以保持协同控制效果；最后，建立了高速曲线轨道上轨道车辆主动悬架的控制机理及其控制器设计方法。在未来，需要用实际车辆进行效果验证，从软件和硬件两个方面保证控制系统的可靠性是实际使用中不可缺少的。较少
