However, the currently prepared ECMs with self-healing function have problems such as irregular particle shape and uneven distribution of components, which affect the efficient play of self-healing function. In this paper, HMX-based energetic microspheres with self-healing function were successfully prepared by microchannel technology, which showed excellent self-healing effect in both Polymer-bonded explosives (PBXs) and Composite solid propellants (CSPs). The experimental results show that the HMX-based energetic microspheres with different binder contents prepared by microchannel technology show regular shape, HMX crystal particles are uniformly wrapped by self-healing binder (GAPU). When the content of GAPU in HMX-based energetic microspheres is 10%, PBXs show excellent self-healing effect and mechanical safety is improved by 400% (raw HMX vs S4, 5 J vs 25 J). As a high-energy component, the burning rate of CSPs is increased by 359.4%, the time (burning temperature &gt; 1700 °C) is prolonged by 333.3%, and the maximum impulse force is increased by 107.3% (CSP-H vs CSP-S4, 0.84 mm/s vs 3.87 mm/s, 0.06 s vs 0.26 s, 0.82 mN vs 1.70 mN). It also has excellent storage performance. The preparation of HMX-based energetic microspheres with self-healing function by microchannel technology provides a new strategy to improve the storage performance of ECMs and the combustion performance of CSPs.</div></div>","PeriodicalId":58209,"journal":{"name":"Defence Technology(防务技术)","volume":"52 ","pages":"Pages 47-59"},"PeriodicalIF":5.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145277877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The floor-occupant-seat local simulation model provides an alternative solution for quickly evaluating the performance of occupant protection systems. However, the error and rationality of the loading of the thin-walled floor in the local model cannot be ignored. This study proposed an equivalent loading method for the local model, which includes two parts: the dimensionality reduction method for acceleration matrix and the joint optimization framework for equivalent node coordinates. In the dimensionality reduction method, the dimension of the acceleration matrix was reduced based on the improved kernel principal component analysis (KPCA), and a dynamic variable bandwidth was introduced to address the limitation of failing to effectively measure the similarity between acceleration data in conventional KPCA. In addition, a least squares problem with forced displacement constraints was constructed to solve the correction matrix, thereby achieving the scale restoration process of the principal component acceleration matrix. The joint optimization framework for coordinates consists of the error assessment of response time histories (EARTH) and Bayesian optimization. In this framework, the local loading error of the equivalent acceleration matrix is taken as the Bayesian optimization objective, which is quantified and scored by EARTH. The expected improvement acquisition function was used to select the new set of the equivalent acceleration node coordinates for the self-updating optimization of the observation dataset and Gaussian process surrogate model. We reduced the dimension of the acceleration matrix from 2256 to 7, while retaining 91% of the information features. The comprehensive error score of occupant's lower limb response in the local model increased from 58.5% to 80.4%. The proposed equivalent loading method provides a solution for the rapid and reliable development of occupant protection systems.</div></div>","PeriodicalId":58209,"journal":{"name":"Defence Technology(防务技术)","volume":"52 ","pages":"Pages 184-206"},"PeriodicalIF":5.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145278358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the hydrothermal process, the addition of BA significantly increased the content of pyrrole nitrogen in the adsorbent. In the activation process, pyrrole nitrogen gradually changed into pyridine nitrogen and graphite nitrogen. Increased BA addition result in a higher specific surface area and microporosity of the adsorbent. The CO₂ adsorption performance test proved that the CGFS-50%-CA sample has the strongest CO₂ adsorption capacity at low temperature, up to 15.59 cm³/g, which is mainly through physical adsorption, and the CGFS-10%-CA sample has the strongest CO₂ adsorption capacity at high temperature, up to 7.31 cm³/g, which is mainly through chemical adsorption.

The method does not need to weaken the strength of shell, and relies on the high stress generated by superposition to cut shell into regular fragments. Additionally, it can be combined with different initiation methods to alter the fragmentation outcomes. In this study, aiming at the fracture strain of metal cylindrical shell driven by explosive charge with waveform regulator, theoretical analysis was first adopted to obtain the prediction model of the fracture strain of cylindrical shell with waveform regulator and the model of the axial distribution of the stress concentration factor. On this basis, both theoretical analysis and numerical models were utilized to investigate the effect of waveform regulator on the initial velocity of fragments. Finally, experiments were conducted to validate the fracture strain prediction model for cylindrical shell with waveform regulator. The research results show that the collision angles of the detonation waves at different axial positions are different, which leads to the stress concentration factor on the shell presenting a trend of gradually decreasing, then sharply increasing, and then rapidly decreasing along the axial direction. Additionally, the changes in the slot spacing and the thickness of outer charge will also affect the stress concentration factor, and the influence of outer charge thickness is relatively large. The smaller the ratio of charge volume to waveform regulator volume, the larger the axial sparse wave intensity and the more the fragment initial velocity decrease. From the initiation end to the non-initiation end, the failure modes of the shell sequentially change from pure shear, to mixed tensile-shear, and finally to pure tensile failure. The experimental results are in good agreement with the calculated results of the fracture strain model, and the maximum relative error is less than 10%, which indicates that the fracture strain prediction model of the cylindrical shell with waveform regulator established in this paper by considering the increase of elastic energy per unit volume caused by stress concentration on the shell is reliable.</div></div>","PeriodicalId":58209,"journal":{"name":"Defence Technology(防务技术)","volume":"52 ","pages":"Pages 84-99"},"PeriodicalIF":5.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145278353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adaptability of powder engines and powdered fuels under different pre-treatment and loading methods should be evaluated.
