Coating Design and Evaluation of Wide Gauge Freight Electric Locomotives

Abstract

In order to make the coating design of a wide-gauge freight electric locomotive more comprehensive, scientific, and rational, fuzzy hierarchical analysis (FAHP) was used to analyse the coating design elements and determine their importance ranking, which in turn guided the completion of the design. The coating scheme was fuzzy evaluated according to the design element indicators and combined with the objective evaluation results of the eye-movement experiments to rank the coating scheme in order of preference. Through the case of the coating design of a wide-gauge freight electric locomotive exported to Belarus, the feasibility of FAHP in the process of locomotive coating design was demonstrated, giving comprehensiveness and rationality to the design process. The evaluation of the scheme through the fuzzy evaluation method and eye-movement experiment provides a theoretical basis for the design evaluation of locomotive coating scheme and reflects the scientific nature of the scheme preference.
