摘要
提出机构运动可靠性的模糊综合评判法 ,根据不同因素可靠度值来判定机构总体性能的可靠度 .先利用单因素评判方法 ,建立隶属函数数学模型 ,再进行多因素模糊综合评判 ,得到机构的总运动可靠度属于哪个评语集 ,最后利用加权平均法将定性的结论定量化 ,计算出机构的总运动可靠度值 ,并引用算例加以说明 .
A method of fuzzy synthesis estimate on motion reliability of mechanism is presented to calculate the overall reliability in the light of the reliability of different factors of mechanism motion. Fuzzy synthesis estimate is done through three aspects of motion reliability of mechanism, and the whole reliability is obtained. Firstly, the subjection degree of each factor should be found. Then, mechanism grade should be calculated by using the method of fuzzy synthesis estimate. Finally, the overall mechanism reliability could be gained through transforming the results.
