Shock Characteristic

The simulation of regular shock wave (e.g., half-sine) can be achieved by the traditional rubber shock simulator, but the practical high-power shock wave characterized by steep prepeak and gentle postpeak is hard to be realized by the same. To tackle this disadvantage, a novel high-power hydraulic shock wave simulator based on the live firing muzzle shock principle was proposed in the current work. The influence of the typical shock characteristic parameters on the shock force wave was investigated via both theoretical deduction and software simulation. According to the obtained data compared with the results, in fact, it can be concluded that the developed hydraulic shock wave simulator can be applied to simulate the real condition of the shocking system. Further, the similarity evaluation of shock wave simulation was achieved based on the curvature distance, and the results stated that the simulation method was reasonable and the structural optimization based on software simulation is also beneficial to the increase of efficiency. Finally, the combination of theoretical analysis and simulation for the development of artillery recoil tester is a comprehensive approach in the design and structure optimization of the recoil system.

Charging Current

High-power-charging (HPC) behavior and extreme ambient temperature not only pose security risks on the operation of lithium-ion batteries but also lead to capacity degradation. Exploring the degradation mechanism under these two conditions is very important for safe and rational use of lithium-ion batteries. To investigate the influence of various charging-current rates on the battery-capacity degradation in a wide temperature range, a cycle-aging test is carried out. Then, the effects of HPC on the capacity degradation at various temperatures are analyzed and discussed using incremental capacity analysis and electrochemical impedance spectroscopy. The analysis results show that a large number of lithium ions accelerate the deintercalation when the HPC cycle rate exceeds 3 C, making the solid electrolyte interphase at the negative surface unstable and vulnerable to destruction, which results in irreversible consumption of active lithium. In addition, the decomposition of electrolyte is significantly promoted when the HPC temperature is more than 30°C, resulting in accelerated consumption of electrode materials and active lithium, which are the main reasons for the capacity degradation of lithium-ion batteries during HPC under various temperatures.

Managing ageing and remaining lifetime of an industrial facility is a concern that must be taken in account by utility as soon as possible in daily activities. The corresponding actions engaged in France are based on 3 major step that are described in the paper: • routine maintenance, • exceptional maintenance, • systematic and periodic review of safety important components and structures sensitive to ageing to assure the effectiveness of the maintenance actions and maintain a high safety level of the plant with a good competitiveness. Following different on-going programs on ageing management of different components, EDF developed its own approach, based on IAEA guidelines, in order to systematically review all the ageing management programs implemented on its 3-loop plants. The methodology is done in 3 steps: • selection of components and justification, • degradation mechanism analysis, • synthesis and consequences on maintenance programs. After a presentation of each step of the procedure a quick overview of the status of application in France is done. Comparison of the methodology with similar methodology used in different other countries is done to close the paper.
