摘要:
为科学准确地分析和评估常导电磁型高速磁浮列车通过平面曲线线路的能力，利用高速磁浮列车运行中的导向间隙、电流以及加速度等状态信息，基于模糊综合评价法提出了可量化的评价指标；在不同的曲线半径、运行速度和有效载荷下，利用本文提出的评价指标对列车的主动导向能力进行了分析和评估；最后，通过实际线路测试验证了评估结果的有效性. 研究结果表明：常导电磁型高速磁浮列车的主动导向能力不仅与导向系统本身的能力有关，还与线路半径、列车运行速度等因素密切相关；提出的方法可以对常导电磁型高速磁浮列车的主动导向能力进行评估，为检验导向系统的实际效用和应用边界提供参考依据.
Abstract:In order to scientifically and accurately analyze and evaluate the ability of electromagnetic high-speed maglev train passing through the plane curve line, a novel quantifiable evaluation index system is proposed based on fuzzy comprehensive evaluation method by using the state information of guide gap, current and acceleration in maglev train operation. The evaluation index is proposed to analyze and evaluate the active guidance ability of the train under different curve radiuses, running speeds and payloads. The effectiveness of evaluation results is verified by the actual line test. The results indicate that the active guidance ability of the electromagnetic high-speed maglev train is closely related not only to the ability of the guidance system itself, but also to the line radius, running speed and other factors. The proposed method is able to evaluate the active guidance ability, and provide a reference basis for verifying the actual utility and application boundary of the guidance system.
