摘要:
混合动力汽车整车控制器(hybrid control unit,HCU) 是保障汽车安全、可靠运行的重要零件之一,因此在HCU 产品设计阶段对其进行失效风险分析尤为重要。基于模糊数学理论建立的针对HCU产品的模糊FMECA 决策方法,通过引入模糊数学理论,对传统FMECA(failure modes,effects and criti?cality analysis,故障模式影响及危害性分析)方法中的专家定性评价结果进行量化处理,形成模糊评价矩阵,并结合加权模型计算各失效模式的综合危害等级,可以有效地将定性评估结果转换成定量评估结果。避免了传统定性分析方法中因主观因素造成的决策失误,能够为HCU 的开发、设计和决策提供科学可靠的风险评估手段。
Abstract:
The hybrid control unit (HCU)is one of the key components ensuring the safe and reliable operation of hybrid electric vehicles. During the design stage of HCU products,it is essential to conduct failure risk analysis. By introducing fuzzy mathematics theory,the fuzzy FMECA decision-making method for HCU products,which is established on the basis of the fuzzy mathematics theory,can quantify the expert qualitative evaluation results in the traditional FMECA,so as to form a fuzzy evaluation matrix. Combined with a weighting model,the comprehensive risk level of each failure mode can be calculated,effectively transforming qualitative assessment results into quantitative ones. It makes up for the decision-making errors caused by subjective factors in the traditional qualitative analysis method and can provide a scientific and reliable risk assessment methods for the development,design,and decision-making of HCU.
