The 7B04-T6 and 30CrMnSiA joints were pretensioned and exposed to hot and humid marine climate for corrosion test. They were taken back after different cycles of test and fatigue-loaded. Then the fatigue life values of six cycles were studied. The fatigue-safe life of the joints was estimated by using the one-sided tolerance factor method. The results show that the fatigue life of the joint specimen is greatly reduced by the interaction of the corrosive environment and fatigue load. Taking the confidence and reliability into consideration, the one-sided tolerance factor method makes it is possible to obtain an accurate estimated value of fatigue-safe life and thus plays a guiding role in the use of engineering application materials.

Aiming at the existing software safety requirements analysis, there are many subjective qualitative analysis with less objective quantitative analysis. First, the weapon equipment software safety requirement index system is constructed in this paper. Secondly, an analysis method based on improved Analytic Hierarchy Process (AHP) and grey clustering model are proposed. The model can solve the problem that the AHP index weight is not objective and the grey clustering model has similar clustering coefficients. Finally, the safety requirement analysis of a certain weapon equipment software system is taken as an example to evaluate the results. The results show that the method can effectively improve the accuracy and scientificity of the assessment.

Effective spare parts inventory management can not only ensure timely maintenance of equipment maintenance activities, but also reduce inventory capital occupation and improve the economic benefits of enterprises. In this paper, we present a condition-based maintenance strategy that considers spare parts issues for systems, with the goal of jointly optimizing conditional-based maintenance and spare parts management. Random systems are gradually degraded and continuously monitored. Spare parts supply using (S-1,S) type inventory strategy. According to the proposed strategy, the replacement of components is based on the actual degree of degradation, which is caused by the demand for spare parts. The Monte Carlo simulation method was used to simulate the proposed condition-based maintenance and spare parts replacement strategy. Therefore, the optimal solution is obtained by jointly optimizing the spare parts and condition-based maintenance of the components. Finally, a numerical example is delivered to show the proposed method.

Residual life estimation is of crucial significance in reliability engineering. Traditional methods are limited when components are characterized as high reliability, long life and small sample size. However, in practical engineering, experts can provide valuable reliability information, which could obviously improve the estimation precision of residual life when compared with conventional approaches. In this paper, a Bayesian method of residual life estimation by utilizing expert knowledge is proposed. Firstly, the prior distribution from expert information is determined. After fusing field lifetime data, posterior distribution can be obtained. Finally, residual life is estimated by the proposed sample-based method and both the Bayes estimate and credible interval are obtained. The proposed method in this paper is validated by the simulation study and the results prove the proposed method is rather satisfactory and robust.

The degradation of data and failure data is used to make the maintenance decision of equipment in this paper. Firstly, the Wiener process is used to build the degradation model which is according to the degradation data of the equipment. Then, the random distribution coefficient of failure threshold is estimated by the failure data of the equipment, and we also derive the analytical expression of the remaining useful lifetime (RUL) distribution of the equipment. Finally, the maintenance decision model is established according to the renewal-reward theory and RUL prediction data which can achieve optimal maintenance strategy of equipment. The simulation example shows that the method in this paper can prolong the run time cost of equipment and effectively reduce the life cycle which has broad application prospects.

Recent research on fault diagnosis mainly focuses on how to improve diagnostic accuracy. For a given accuracy level, a variety of convolutional neural network architectures have been developed and available to achieve the specific accuracy level. With equivalent fault diagnosis accuracy, smaller convolutional neural network structure offers at least three advantages: (1) it can be deployed on hardware with limited memory, such as FPGAs; (2) the training of smaller convolutional neural networks can be faster under the same processor performance; (3) smaller network structures require less communication across severs during distributed training. So, in this paper, an improved convolutional neural network is constructed, and the following strategies are used to reduce network parameters and further make the convolutional neural networks with smaller structures: (1) equivalent replacement of large-scale convolution layers by multiple small-sized convolution layers; (2) avoid using a fully connected layer, and replace with a global pooling layer. Meanwhile, to ensure the model’s fault diagnosis accuracy and training effectiveness, inspired by the network in network, a 1*1 convolutional layer is inserted into a traditional convolutional layer to improve feature expression, and the batch-normalization layer is used to increase the training effectiveness.
