发动机环境适应性模糊评价研究

Research on Engine Environmental Adaptability Based on Fuzzy Evaluation

针对我国特种车辆发动机环境适应性评价研究缺乏,评判体系不合理的问题,基于模糊识别理论,参照美军环境适应性试验标准,采用层次分析法和专家打分法,确定了发动机环境适应性评价模糊集、基准向量及其权重,建立了环境适应性评价模型,对我国典型地区的发动机环境适应性进行了分析与评估,结果表明:西藏班戈发动机环境适应性等级为"差",新疆吐鲁番环境适应性等级为"较好",黑龙江漠河环境适应性等级为"一般"。

Based on the tuzzy evaluation theory and referring to the criterion of American army environmental adaptability experiment standard, the engine environmental adaptability evaluation fuzzy sets, baseline vectors and weight coefficients were determined using hierarchical analysis and expert scoring methods. Then the environmental adaptability evaluation model was established to analyze and evaluate the engine environmental adaptability in typical areas. The results indicate that the engine environmental adaptability is ranked ＂poor＂ and ＂better＂ respectively in Bange and Turpan, and in Mohe, Heilongjiang Province ranked ＂average＂.
