摘要
针对现有汽车EPS系统可靠性评估传统方法的局限性,应用GO法对EPS系统进行可靠性分析。阐述了汽车EPS系统GO法的具体分析步骤,建立了相应GO图模型,进行了定性分析和精确的定量分析。通过与FTA分析和FMEA分析法对同一EPS的分析对比验证了GO法在汽车EPS进行可靠性分析中的实用性和正确性。结果表明应用GO法进行汽车EPS可靠性分析,是一种具有实际操作意义的解决方案,可以减少计算工作量和降低建模差错。
In view of the limitations of the traditional methods of vehicle EPS system reliability assessment, the GO methodology was applied to analyze the system reliability. In this paper, specific analysis steps of the GO methodology were described, the corresponding GO diagram model was built, and a precise quantitative analysis and qualitative analysis were given. Finally, by comparing the analysis of the EPS with that of the FTA （fault tree analysis） and the FMEA（failure modes and effects analysis） , accuracy of the GO method was verified. The results show that the Go
