Influence Analysis of Vibration Control Parameters for High-Speed Maglev Train-Bridge Coupling

  • 摘要:

    磁浮列车悬浮系统控制参数取值不当可能导致车-桥系统异常振动. 因此,明确悬浮系统控制参数与磁浮车-桥系统动力响应之间的关系十分重要. 首先,建立包含比例-微分控制的5节编组磁浮列车动力学模型和20跨简支梁桥有限元模型;其次,与实测结果进行对比验证所建立模型的正确性;最后,计算车速430 km/h时不同控制参数下列车和桥梁的动力响应. 结果表明:增大比例系数会使悬浮和导向系统刚度增大,增大微分系数会使悬浮和导向系统阻尼增大;车体竖向加速度随比例和微分系数的增大而增大,车体横向加速度随比例系数的增大而增大;悬浮间隙和桥梁竖向加速度均随比例系数的增大而减小,随微分系数的增大而增大;导向间隙随微分系数的增大而减小,比例系数对导向间隙的影响较小;桥梁横向加速度随比例系数的增大而减小,随微分系数的增大而增大;桥梁竖向加速度主要受电磁力中悬浮电磁铁长度特征频率1~12倍频的影响,桥梁横向加速度主要受导向磁极长度特征频率及其2倍频和导向电磁铁长度特征频率2倍频及4倍频的影响;为减小车-桥系统动力响应,综合建议竖向比例和微分系数的取值范围分别为3000~4000和10~25,横向比例和微分系数的取值范围分别为4000~5000和10~25.
