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 highspeed 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.
