Abstract EN
Fuzzy dynamic reliability models of mechanical parallel systems with respect to stress parameters and strength parameters are developed in this paper.
Strength degradation path dependence (SDPD) and failure dependence of components in the system are two main problems to be addressed in developing fuzzy dynamic reliability of mechanical systems, which are taken into account in the proposed reliability models.
In addition, the SDPD sensitivity function and the failure dependence sensitivity function are defined to analyze the influences of the fuzzy characteristics of stress on the effects of SDPD and failure dependence of mechanical components on dynamic reliability.
The bolted joint systems for connection between launch vehicle and satellite are chosen as illustrative examples to demonstrate the proposed model.
Moreover, Monte Carlo simulations are carried out to validate the effectiveness of the proposed models.
The results show that SDPD and failure dependence of components have significant impacts on fuzzy dynamic reliability of mechanical systems.
Besides, the influences of the fuzzy characteristics of stress on SDPD sensitivity and that on failure dependence sensitivity are different.
