Preventive reconfiguration can guarantee the distribution network operate with a certain of safe margin, while the frequent changes of network topology will decrease the stability of system and increase operating costs. Considering the charge-discharge characteristics of energy storage and the maximum power supply capability(PSC) of network, the minimum reconfiguration times during a day was taken as the first-level objective function and the maximum output capability of energy storage system and the PSC index (PSCI) were considered as the second-level objective function. Then, a multi-level objective model of preventive reconfiguration was established. A strategy involving energy storage output and network reconfiguration was developed and a combining regulation method was proposed. When the PSCI was below the pre-defined warning value, it was prior to regulate with energy storage and the combining regulation was conducted when the former couldn't meet the requirement. The generalized reduced gradient algorithm and hybrid particle swarm algorithm were used to solve the target problem. Finally, comparative calculation and analysis were conducted on IEEE-33 bus sample system. The simulation results showed the backup function of energy storage and the frequent changes of network topology could be avoided, and the model and the strategy were finally validated. The researching achievement has a certain significance for using preventive reconfiguration to improve the network operating safety and reliability.

In order to overcome the adverse phenomenon of polycrystalline diamond layer peeling off and passivation serious when integrated polycrystalline diamond compact (PDC) suffers overload, which results in the rapid decline in its cutting function, a new embedded PDC is presented. Based on the uniform-style design concept and triangle stable property in regular hexagon, a ring-embedded PDC of which six teeth surround with central tooth was designed. It was embedded in the new drill bit shoulder to test its cutting performance. Meanwhile, combined with field test, the wear property between new PDC drill bit and general PDC drill bit was compared. The results showed that:the embedded tooth and carbide matrix were combined by brazing welding, which not only exerted the high abrasion resistance of polycrystalline diamond layer, but also combined with the good impact performance of carbide matrix. Compared with general PDC, the ring-embedded PDC had stronger "eating ability", meanwhile, different polycrystalline diamond layers would participate in cutting rock which effectively avoided the stress concentration phenomenon of integrated PDC. According to the established 3D cutting mechanical model, the rock local displacement-stress parameter under the action of shear stress was solved. Additionally, the analysis model could be applied to other types of PDC via adjusting the embedded programs. The research results will provide important reference value for the research of PDC wear law, cutting performance and the research of new PDC drill bit.

As the traditional fit among interconnecting components, interference fit has such advantages as high load-carrying capacity and simple structure, and it is widely used in mechanical engineering field. However, the majority of studies are limited within the interconnection of single layer or less than three layers. With the increasing of application of multi-layer interference fit in mechanical devices, in order to further improve design theory of multi-layer interference fit, on the basis of thick-walled cylinder theory, the relationship between the amount of interference and the displacement of inner and outer diameter was deduced through the analysis on the geometrical relationship among cylinders, and the equation of N-layer interference coupling which involved coupling pressure and amount of interference was derived. By means of the derived analytical method and Abaqus, the coupling pressure of interference fit and the stress concentration phenomenon on both ends of coupling surface were comparatively analyzed. The results showed that coupling pressure of inner layer increased with the increase of layer amount in N-layer interference fit, and the coupling pressure decreased from inner to outer layer, the results of analytical method and numerical method were basically consistent, the relative error of medium point was less than 4%, which showed that such analytical method is reliable for N-layer interference fit design. Meanwhile, the numerical method showed that the stress concentration existed on both ends of the coupling surface, and the stress concentration factor was smaller in the inner layer of each model, while it increased from inner to outer layer. The proposed algorithms and rules can provide guidance and help for the design of N-layer interference fit.

The motion patterns of fin ray of a bionic undulating fin are normally divided into two types:constant amplitude and variable amplitude. The initial experimental tests reveal that there are significant differences on propulsion performences between these two motion patterns. In order to reveal the inherent cause for such differences, a bionic undulating fin was developed and the relevant kinematic equations were established. By taking the advantages of computational fluid dynamic (CFD), the pressure distribution on fin surface under different kinematic parameters was compared. The variation of non-dimensional drag coefficient with time under the two patterns was presented. Meanwhile, the variation of time-averaged non-dimensional drag coefficient with undulating frequency, amplitude and wavelength was also presented. In addition, the velocity contour and pressure contour in transversal surface along fin ray were illustrated. The results showed that:the time-averaged propulsion force increased with the increasement of frequency, amplitude and wavelength. However, the force produced by constant amplitude was always less than that of variable amplitude. Moreover, the velocity contour and pressure contour in transversal surface along fin ray between the two motion patterns were of great differences, but little differences were occurred in the vortex distribution in the longitudinal cross-section along fin, which indicated that the main influence of the two motion patterns might be from the transversal section along fin ray. A further discussion is implemented to illustrate the principle of aquatic organisms with undulating fins that propel themselves effectively. It provides a reference for the development of a high performance bionic undulating fin propulsion system.
