A Self-normalizing Convolutional Neural Network (SCNN) algorithm can have a much faster convergent rate than that of a traditional Convolution Neural Network (CNN) as the former does not require a Batch Normalization (BN) during the network training process. SCNN is employed in this study for an automated bearing fault diagnosis based on the frequency domain fault feature extracted from acoustic emission signals acquired from a bearing test rig. In the process, a fast Fourier transform is employed first to transform the time domain signal into the frequency domain, the spectra are then used as the samples to train the SCNN model. The trained network is utilized to identify various bearing conditions under both constant and varying speeds. It is shown that the proposed technique can achieve a 100 percent recognition rate in the constant speed case and a 99.4 percent accuracy in the varying speed case. It is also showed in a comparison study that SCNN can have a much faster fault recognition rate than the traditional CNN.

The copper-filled laminated micropore of the HDI board is the structural basis for the electrical interconnection between the conductive layers of the metal, and its quality determines the reliability of the HDI board. Due to the limitation of technology, it is unavoidable that there are microvoids in the micropore to cause stress concentration, which will greatly reduce the thermal fatigue life of the micropore. In order to study the life model of micropore with microvoid, the different characteristic parameters of microvoid in laminated micropore and the design parameters of HDI board were analyzed in this paper. Taking [3+6+3] the most common commercial HDI board as an example, based on the Box-Behnken experimental design principle, a continuous variable surface model with microporous strain as the response was established. The model can consider the influence of multiple variables in the process of HDI design and board acceptance. It can evaluate multiple factors affecting the micropore life and their interaction, and improve the efficiency and reliability of the design.

Accelerated degradation test (ADT) is considered as a method for obtaining product degradation data in a short period of time, and the life and reliability of the product are inferred under the conditions of use.In order to ensure the effectiveness of ADT, guaranting that the failure mechanism of the product under each accelerated stress is consistent with the failure mechanism under normal stress is necessary. Therefore, it is necessary to carry out an accelerated degradation failure mechanism consistency discriminant test. At present, the determination of the test variables in the accelerated degradation failure mechanism consistency discriminant test is mainly based on experience, and lacks a set of experimental optimal methods with theoretical basis. In this paper, in order to solve the above problems, save sample capacity and reduce testing time, D-Optimality for step stress is applied to optimal design of accelerated degradation failure mechanism consistency discriminant test based on Wiener process.First, we apply Wiener process to describe an accelerated degradation failure mechanism consistency discriminant test. Then, we apply D-Optimality for step stress that by using the expenditure function and the decision variable function as restrictions, the sample capacity, the optimal total test time and the optimal time at each stress level are given. At last, a case study is used to illustrate the proposed method.

The abnormal delamination of Printed Circuit Board (PCB) during lead-free wave soldering was analyzed by means of visual inspection, cross-section, and thermal analysis. The results showed that PCB absorption moisture causes the saturated vapor pressure during welding inside the substrate exceeds the binding force of the resin and the glass fiber, which induce the delamination of PCB when wave soldering.

In this paper, the fuzzy relative entropy of fuzzy information theory is introduced for the spatial target orbit information and its related characteristics are discussed. For the tens of thousands of spatial target orbital feature information in the space target orbit information database, the J2000 inertial mean orbit elements are used to construct the respective fuzzy feature vectors. The fuzzy relative entropy discriminant algorithm is used to model and analyze the big data information of the target and the orbit information base. After 10 sets of near-ground circular orbits and 6 sets of medium-high orbits to be identified and fuzzy relative entropy recognition calculation of the orbit information database, the proportion of the target to be identified correctly identified as a unique spatial target can reach up to 63%. Due to the influence of the orbital error and the threshold error, the initial identification of the orbit is often as many as several dozen. Compared with the traditional empirical threshold interval recognition technology that relies on the orbit feature information, the method can greatly improve the success rate of the recognition calculation. Since the spatial information of the target orbit feature itself is fuzzy, there is always a deviation from the actual rail orbit calculation. Therefore, the fuzzy relative entropy method is reasonable. The method applies the information discrimination characteristics of fuzzy information theory to measure the spatial target orbit. Compared with the traditional orbit feature information recognition method, it has the characteristics of high computational efficiency, large information discrimination, strong anti-interference performance and high recognition success rate. It has a good application prospect in the field of space target (fragment) detection and identification.

As an important load-bearing structure in the field of mechanics, the known basic mechanical behavior of cantilever plate has been able to solve most of the engineering problems. However, the structural details and working environment of the sealing plate are much more complicated than that of the cantilever plate, which plays an important role in ensuring flight safety. In view of this, this paper is devoted to studying the plastic deformation accumulation mechanism of the sealing plate in practical engineering, so as to estimate its service life and optimize the maintenance cycle. The basic mechanical behavior of cantilever beam structure is introduced in this paper. Then, the influence of shape change on the plastic deformation of the cantilever plate is studied. Finally, the complex constraints and periodic loads are introduced into the cantilever plate structure to form the sealing plate model, and the mechanism of plastic deformation accumulation is illustrated.
