摘要: 针对地铁线路平顺性差及轮轨磨耗严重引发的车辆横向振动剧烈问题,提出基于阀控式半主动液压减振器的横向振动控制优化方法,以提升车辆运行平稳性与线路适应性。建立120 km/h地铁车辆-半主动减振系统机电耦合动力学与控制模型,利用天棚阻尼控制等5种策略,结合减振器力-速-电流特性实测数据,系统研究轮轨匹配状态、响应时滞与控制参数间的交互影响机制。仿真结果表明:天棚连续阻尼、加速度阻尼混合控制策略的振动抑制效果优于另外3种天棚阻尼策略;当减振器反比例阀的驱动电流较小时,减振器输出力较大,最大可达到10 kN,致使车体平稳性指标、舒适度指标、横向加速度等也较大,即振动改善效果变差;当反比例阀的驱动电流大于14 mA时,减振器输出力大小适中,为5 kN左右,此时车体横向平稳性和加速度等指标明显降低,建议驱动电流为14~16 mA;当运行速度越高和轮轨磨耗越严重时,半主动减振器对车体振动的改善效果越显著;不同控制策略对半主动减振器响应时滞的敏感性存在差异,即允许的临界时滞量不同,车轮磨耗状态较新轮状态允许的临界时滞更小。上述结论为阀控式减振器工程实际应用中面临的控制策略选取、时滞量影响和振动控制效能问题等提供了理论研究参考。

Abstract: To address severe lateral vibration issues caused by track irregularity of metro railway and excessive wheel-rail wear, this study proposes a valve-controlled semi-active hydraulic damper-based optimization method for lateral vibration control to enhance vehicle ride comfort and track adaptability. A mechatronic coupled dynamics and control model was developed for a 120 km/h subway vehicle equipped with a semi-active damping system, incorporating five control strategies including skyhook damping control. Through integration with experimentally measured damper force-velocity-current characteristics, the study systematically investigated the interaction mechanisms among wheel-rail matching conditions, response delay, and control parameters. Simulation results indicate that the hybrid control strategy combining continuous skyhook damping with acceleration damping achieves superior vibration suppression compared to three alternative skyhook damping strategies. When the damper’s proportional valve operates with driving current, the output force increases substantially (up to 10 kN), resulting in increased Sperling index, ride comfort index, and lateral acceleration, consequently diminishing vibration mitigation effectiveness. In contrast, when the driving current exceeds 14 mA, the damper force stabilizes at approximately 5 kN, achieving significant improvements in both lateral ride comfort and vibration reduction. Thus, an optimal driving current of 14-16 mA is recommended. Furthermore, the effectiveness of semi-active dampers in mitigating vehicle vibration becomes more pronounced at higher speeds and under severe wheel-rail wear conditions. Different control strategies exhibit distinct sensitivity characteristics to response delays in semi-active dampers, leading to strategy-dependent critical delay thresholds. Notably, worn wheel conditions exhibit reduced tolerance to time delay compared to new wheel conditions. These conclusions provide111 theoretical guidance for addressing practical engineering challenges in valve-controlled hydraulic damper applications, specially concerning optimal control strategy selection, time delay impact assessment, and vibration control efficacy.
