摘　　要：为提高挖掘机整机工作的经济性能,有效降低燃油消耗对环境的污染,建立基于灰色关联分析和优劣解距离法相结合的挖掘机油耗和效率综合评价模型。通过距离函数对主客观权重进行组合赋权,系统量化评价指标;结合灰色关联分析和优劣解距离法对评价对象的距离和关联度进行计算,相比传统灰色关联分析,扩大了关联区间,提高了系统的分辨能力。使用该模型对挖掘机装车工况下5种模式的油耗和效率进行综合评价,结果表明:自定义75模式下挖掘机的油耗和效率最优,关联区间扩大了0.312 8,并在相同油耗下效率提升7.7%。该方法可应用于挖掘机的油耗和效率的综合评价中。In order to improve the economic performance of the excavator and effectively reduce the pollution of the environment by fuel consumption, a comprehensive evaluation model of excavator fuel consumption and efficiency based on the combination of gray correlation analysis and the distance method of superiority and inferiority solution is established. The evaluation indexes are quantified systematically by combining the objective and subjective weights with the distance function. At the same time, the distance and correlation degree of the evaluation objects are calculated by combining the gray correlation analysis and the superiority-disadvantage solution distance method, which expands the correlation interval and improves the discrimination ability of the system compared with the traditional gray correlation analysis. The results show that the fuel consumption and efficiency of the excavator under the custom 75 mode are optimal, the correlation interval is expanded by 0.3128, and the efficiency is improved by 7.7% under the same fuel consumption, which meets the demand of practical engineering applications and can be applied in the comprehensive evaluation of fuel consumption and efficiency of excavators.
