| 1 | 基于随机减量法的分布式结构模态参数识别显示文摘分区进行平行分析处理的技术已成为大型结构密集布置无线智能传感器网络检测结构系统的重要任务。提出基于随机减量法的分布式数据采集和模态识别方法。以两边简支板模型试验为例,采用ISM400无线智能传感器,通过自然激励法获得测试结构的响应信号,计算随机减量函数,然后运用特征系统实现算法提取系统的状态空间参数,并结合稳定图的方法剔除虚假模态,识别出结构的模态性能参数。以模态置信度为判据对比分析分布式算法与集中式算法的识别效果,结果表明两种算法吻合良好。 | 逯静洲 Sung Han Sim Billie F.Spencer Jr. | 2017 | 振动与冲击2017，36，17： | 7 |
| 2 | 基于分布式传感网络的结构模态识别方法显示文摘结构的模态参数识别是结构健康监测系统的基本任务。随着工程结构的日益大型化和复杂化,振动测试时需要布置大量的传感器。传统的集中采集和处理技术将难以胜任海量数据的处理要求,采用无线智能传感器的结构健康监测系统正是应运而生的新方向,而分布式采集和处理是其特点。在无线智能传感网络拓扑结构中采用分布式算法求解结构整体振型,利用随机子空间法识别各子结构模态,结合粒子群优化算法调整子振型获取结构整体振型。通过混凝土钢管拱桥模型试验验证了分布式算法的可行性,并利用模态置信度(MAC)对比分析了由分布式模态识别方法和集中式模态识别方法得到的结果,结果表明两种算法吻合较好。 | 张敏 谢慧才 Sung han Sim B F Spencer Jr | 2010 | 土木工程学报2010，43，3： | 2 |

| 4 | Effect of silicon carbide-based iron catalyst on reactor optimization for non-oxidative direct conversion of methane显示文摘The conversion of methane to olefins,aromatics,and hydrogen(MTOAH)can be used to stably obtain hydrocarbons when the effect of the catalytic surface is optimized from the reaction engineering perspective.In this study,Fe/Si C catalysts were packed into a quartz tube reactor.The catalytic surfaces of Si C and the impregnated Fe species decreased the apparent activation energies(E_a)of methane consumption in the blank reactor between 965 and 1020℃.Consequently,the hydrocarbon yield increased by 2.4times at 1020℃.Based on the model reactions of ethane,ethylene,and acetylene mixed with hydrogen in the range of 500-1020℃,an excess amount of Fe in the reactor favored the C-C coupling reaction over the selective hydrogenation of acetylene;consequently,coke formation was favored over the hydrogenation reaction.The gas-phase reactions and catalyst properties were optimized to increase hydrocarbon yields while reducing coke selectivity.The 0.2Fe catalyst-packed reactor(0.26 wt%Fe)resulted in a hydrocarbon yield of 7.1%and a coke selectivity of<2%when the ratio of the void space of the postcatalyst zone to the catalyst space was adjusted to be≥2.Based on these findings,the facile approach of decoupling the reaction zone between the catalyst surface and the gas-phase reaction can provide insights into catalytic reactor design,thereby facilitating the scale-up from the laboratory to the commercial scale. | Eun-hae Sim Sung Woo Lee Jin Ju Lee Seung Ju Han Jung Ho Shin Gracia Lee Sungrok Ko Kwan-Young Lee Yong Tae Kim | 2023 | Journal of Energy Chemistry2023，，6： | 0 |
