摘要

摘要: 为提高磨齿机金刚滚轮转动系统的可靠性,将集对分析理论引入到金刚滚轮转动系统故障树分析过程中,建立了集对分析理论与故障树相结合的集对故障树模型,推导了该模型中常用的逻辑门集对算子并给出了模型的基本分析流程,计算了金刚滚轮转动系统故障发生的可能性区间,提出了其失效的改进措施。该方法有效降低了系统转动失效的可能性,提高了数控磨齿机的可靠性。

Abstract: To improve the reliability of diamond roller rotation system in CNC gear grinding machine,the set pair analysis theory is introduced into the process of the fault tree analysis of diamond roller rotation system in this paper. A new reliability model was established,which combined the theory of set pair analysis with the fault tree analysis method. The logic gate set to operator commonly used in the model and the basic analysis process were presented. The failure probability interval of diamond roller rotation system was calculated and the improvement measure against invalidation was put forward. Results show that the method effectively reduces the possibility of system turn failure and improves the reliability of CNC gear grinding machine.
