中文摘要:加工中心冷却系统的故障信息常常具有很强的模糊性。常规故障模式影响与危害度分析方法由于仅考虑故障发生频率和严重程度,当考虑故障检测和维修难易程度时,难以给出有效而准确的分析结果。因此提出应用模糊综合评判方法进行危害度分析。综合考虑了故障发生概率、故障严重程度、测试性和维修性等因素,将定性问题进行定量分析,以某加工中心冷却系统为例,计算出冷却系统故障模式危害度,并以此作为判断可靠性改进方向的依据。结果表明,液、气、油堵塞故障模式的危害性最大,与实际相符。

Abstract:The failure information of the cooling system of machining center is fuzzy frequently. The normal analysis method of failure mode critically only considers the failure probability and serious degree. When the testing and the maintainability of failure are considered, the failure mode criticality can not be accurately analyzed by FMECA. The fuzzy theory was proposed to analyze the failure mode criticality. It comprehensively included the failure probability, the failure serious degree, the testing and the maintainability of failure, which could carried out the qualitative question quantitatively. The failure mode criticality of cooling system of a machining center was calculated to determine the direction of improving reliability. The results showed that the criticality of jam stem was serious, which was consistent with the facts.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
