Bayesian Network has an advantage in dealing with uncertainty. But It is difficult to construct a scientific and rational Bayesian Network model in practice application. In order to solve this problem, a novel method for constructing Bayesian Network by integrating Failure Mode and Effect Analysis (FMEA) with Fault Tree Analysis (FTA) was proposed. Firstly, the structure matrix representations of...
Dynamic voltage signal across solder joints during mechanical vibration test was monitored and collected real-timely with a self-designed data acquisition system. Failure process of solder joint was studied by processing and analyzing data. In the paper, lifetime of solder joint was also compared by changing solder joint location, solder joint composition and vibration acceleration. Results indicated...
According to the relationship between the natural frequency of a system and the excitation frequency, the resonance rule of fuzzy failure for the multi-freedom vibration system is built. The fuzzy resonance reliability of vibration system based on the importance sampling method has a more reasonable measurement of the probability of vibration system on resonant failure. The example on fuzzy resonance...
In order to reduce the computational cost of engineering analysis in the reliability assessment of structures, the response surface method (RSM) has been widely used in the literatures. This work examines the application of support vector machine (SVM) to the reliability assessment of structures. A new SVM based RSM is proposed for structural reliability assessment, in which an efficient sampling...
