Research on a Comprehensive Evaluation Method of Train Anti-Slip System Performance

The quality of a train’s braking anti-slip control system has a significant impact on train safety and braking performance. Currently, there is no established standard evaluation method for anti-slip control systems, making it an important area of research in the academic community. This article comprehensively considers four key indexes: adhesive coefficient utilization rate, air consumption increase ratio, wheel slip work, and anti-slip valve action frequency. The evaluation system takes into account the influence of load layer and braking level, and proposes a comprehensive evaluation method for train anti-slip control based on multi-factor hierarchical analysis. A series of experiments were conducted using a semi-physical simulation test bench for anti-slip evaluation, aimed at comprehensively evaluating two different anti-slip control strategies. By applying the method proposed in this article, the above four indexes and their corresponding weights of two anti-slip control strategies under different conditions were calculated. Finally, the comprehensive evaluation result R1 of anti-slip control strategy 1 was calculated as 0.8389, while the comprehensive evaluation result R2 of anti-slip control strategy 2 was calculated as 0.7912. Based on the comprehensive evaluation results, it is evident that the anti-slip comprehensive evaluation method established in this article is comprehensive and scientific, with concise and clear evaluation results. This method carries certain reference significance for the design of future anti-slip evaluation methods.
