摘  要:
论述了腐蚀的分类、机理及影响因素,提出机械零件腐蚀深度的测量值呈正态分布,并依据机械零件腐蚀的基本规律及其模糊性,建立了数学模型,推导了机械零件耐腐蚀性的模糊可靠性计算公式,结合实例,编写了机械零件耐腐蚀模糊可靠度计算的Matlab程序,为预测机械零件剩余寿命提供参考。

摘  要:
In this paper,the corrosion types,mechanism and influence factors are discussed.It points out that the corrosion depth is the normal distribution.Based on the basic orderliness and illegibility characteristic of the parts corrosion,the mathmatics model is set up,the paper also dissertates the fuzzy reliability calculation method.The Matlab program for calculating the fuzzy reliability of the mechanism parts is developed with a practical example.This can provide a reference for residual service life prediction of parts.
