载荷多次作用下的零件模糊可靠度模型

The Fuzzy Reliability Model for Parts Under Multiple Loadings

针对载荷强度干涉模型,载荷和强度带有随机模糊性的情况,研究了模糊载荷多次作用下的零件可靠度及计算.对于载荷多次冲击,累积损伤是随机模糊量的冲击过程,研究了零件可靠度的计算并给出了计算实例.

For the case of load-strength interference model in which the load and strength are randomly fuzzy,we have studied the reliability of parts and their calculation under multiple loadings.As the accumulative damage is blurry,our calculation of reliability for the parts is given with numerical examples.
