【摘要】 结合多柔体系统动力学和模糊可靠性理论,提出柔性机构可靠性模糊综合评价方法。该方法利用多柔体系统随机模拟方法得到不同构件的可靠度值,确定单因素的隶属度函数,按照柔性机构的运动参数可靠度进行单因素评价,根据不同构件的可靠度再进行多因素综合评价,得到整个柔性机构系统的总体可靠度的评价。通过算例证明该方法对大型复杂非线性柔性机构系统整体可靠性评价是有效可行的。更多还原

【Abstract】 By the analysis of flexible multibody and fuzzy theory,the reliability assessment method of flexible mechanism system was presented.In this method,the reliability of the components can be calculated by stochastic simulation of flexible mechanism.Firstly,assessment based on single factor can be decided after subjection degree of each factor was found.Then,fuzzy synthesis assessment based on all factors can be got.Finally,overall system dynamic reliability assessment of flexible mechanism can be gained.The results of sample prove the method is available.更多还原
