摘要
研究目的旨在建立智能机器人机械臂总体动态可靠性的评价方法,根据智能机器人机械臂各运动参数的概率信息,利用模糊方法,确定单因素的隶属度函数,按照运动参数可靠度进行单因素模糊评价,得到不同构件的可靠度评价;然后根据粗糙集理论判断各个构件对机械臂总体可靠性的影响,对概率信息进行约简;再根据不同构件的可靠度进行多因素模糊综合评价,得到整个智能机器人机械臂的总体可靠度的评价。通过算例证明该方法对复杂智能机器人机械臂总体可靠性评价是有效可行的。
The purpose of the research is to present a methodology on overall systematic dynamic reliability assessment of intelligence robot arm. Firstly, fuzzy assessment of each component based on single factor can be decided after subjection degree of each motive factor has been found. Then, Rough sets （RS） theory is applied to reduce the unimportant and unnecessary reliability information which influenced the overall system dynamic reliability assessment. Finally, fuzzy synthesis assessment based on all factors can be got and the overall systematic dynamic reliability assessment of intelligence robot arm can be gained. The results of sample prove the method is available.
