| 摘 要： | 在设计初始阶段，机械产品的可靠性数据往往十分缺乏，且具有一定的模糊性，计算繁杂，给机械可靠性预计带来了困难。采用模糊综合评判的方法，并建立机械系统可靠性指标模糊预计可视化系统，能较好地解决该问题。模糊综合评判能综合运用专家经验和模糊信息，可方便地应用于评估可靠性影响因素。在评估结果的基础上，再利用模糊推理理论对可靠性的预计值进行推理。该方法尤其适用于复杂机械产品设计初期的可靠性预计，弥补了现有可靠性预计方法的不足。通过实例讨论了其具体应用方法。所建立的机械系统可靠性指标模糊预计可视化系统可方便地应用于机械工程领域。

| Abstract: | In the initial design stage(IDS),the lack of reliability data and some fuzzy characteristics make the reliability index prediction of the mechanical system very difficult.The problem is solved by using the method of fuzzy synthetically assessment(FSA) and designing the MSRIP visual system(MRPFPVS).FSA can well utilize experts' experience and fuzzy data,so it is used to assess the influence factors of reliability.On the basis of the assessment results,the predicted reliability values are inferred by the fuzz... |
