摘要
为克服现有焊接机器人系统可靠性数据缺失,研究了一种基于模糊理论的可靠性模糊预计方法。该方法对影响PR1400焊接机器人系统可靠性的重要度、工作时间等因素进行了三角函数模糊化处理,利用λ截集的Zadeh扩展理论求解若干个模糊数的模糊权重平均值;最后运用质心法得到了PR1400焊接机器人各子系统的评分系数,确定了PR1400焊接机器人系统的MTBF值。
In order to overcome the existing lack of welding robot system reliability data, it presents a kind of reli- ability prediction method based on the fuzzy theory. Fuzzy method is utilized to process the importance, work time and other factors affecting the reliability of PR1400 welding robot system, and the fuzzy number weighted average is obtained with extended trap Zadeh. Finally the rating of the subsystems of the coefficient PR1400 welding robot is obtained with qualitative method as well as the MTBF of PR1400 welding robot system.
