Composites with both lightweight and high strength have tremendous demands in aerospace, rail transit, military, etc., especially for ones strong high-strain-rate dynamic impact resistance. Among them, bioinspired helicoidal composites is one type of them. Currently, due to the limitation fabrication, only 0, 45, 90° been investigated enhance Other angle not completely explored yet. Here, we fabricated a series composite specimens 0°–90° angles by Fused Deposition Modeling (FDM), tested...
Due to the large surface-area-to-volume ratio, microchannel heat exchangers have a higher transfer rate compared with traditional scale exchangers. In this study, optimum cavity high and low flow resistance is designed further improve exchangers’ thermal performance. A three-dimensional laminar model, consisting of Navier–Stokes equations an energy conservation equation solved conjugate between silicon basement deionized water taken into consideration. The impact shape, aspect size spacing...
We conducted systematic numerical investigations of the flow characteristics within entrance region rectangular microchannels. The effects geometrical aspect ratio and roughness on lengths were analyzed. incompressible laminar Navier–Stokes equations solved using finite volume method (FVM). In simulation, hydraulic diameters ( D h ) ranging from 50 to 200 µm studied, ratios 1, 1.25, 1.5, 1.75, 2 considered as well. working fluid was set water, Reynolds number ranged 0.5 100. results showed a...
摘要: 在车削加工中,零件质量是生产者需要密切关注的问题。表面粗糙度作为评价零件质量的一项重要指标,选择满意的切削参数来提高表面粗糙度可有效提高零件质量。为提高表面粗糙度的预测精度,在现有研究基础之上提出一种分段的表面粗糙度理论解析模型对表面粗糙度进行预测。同时尝试采用双深度Q网络(DDQN)优化支持向量回归(SVR)提高数据驱动模型的预测性能,探寻DDQN优化SVR内部参数的环境设计,并且与其他算法对比了其优化效果与稳定性。基于45钢的车削试验,验证分段的表面粗糙度理论模型和DDQN-SVR预测模型的有效性,为基于表面粗糙度的切削参数选择提供了较好的技术支持。
A damage index describing severity based on the Auto correlation function at Maximum point value Vector (AMV) is proposed for assessment as well locating described in this study. The detectability of AMV-based detection method compared with Mean Strain Energy (MSE) and Generalized Flexibility Matrix (GFM) method, to show its efficiency localizing simplicity conduct analysis. Moreover, a procedure estimate using sensitivity analysis introduced. stiffness reduction twelve-story shear frame...
A high oxygen content can lead to metallurgical defects such as holes and microcracks in the products of selective laser melting (SLM) that significantly reduce density mechanical properties a denture. In this study, batch Co–Cr alloy powder was subjected forced oxidation. SLM used prepare specimens from before after treatment for performance tests. The results showed powders with contents 184 616 ppm could both achieve good shaping under identical conditions. There no significant difference...
