Research on Impact Load Inversion Based on Compressive Sampling and Model Analysis [PDF]
近年来,许多学者针对大型结构的冲击载荷识别进行研究,以期提高这些结构的安全性、降低维护费用、延长使用寿命。在大型结构健康监测中,如何快速、准确地获得冲击力是一个值得深入研究的问题。本文提出了基于压缩采样信号的模态分析方法,取代基于有限元分析的模态分析方法,克服传统冲击载荷反演需要依赖结构有限元模型的问题。同时,基于压缩采样理论提出了一种冲击载荷识别方法,其中包含了稀疏模型和重构优化模型。该方法能够克服存储及传输的响应信号数据量过于庞大的问题。最后,以大型航空铝板仿真实验举例验证该冲击载荷反演方法的可行性。

Evaluating models of expert judgment to inform assessment of ecosystem viability and collapse
Abstract Expert judgment underpins assessment of threatened ecosystems. However, experts are often narrowly defined, and variability in their judgments may be substantial. Models built from structured elicitation with large diverse expert panels can contribute to more consistent and transparent decision‐making.

Research and Design of Wireless Network for SHM Based on ZigBee Protocol [PDF]
结构建筑物健康监测(SHM)是目前土木学科研究的前沿课题之一。每个建筑物都有固有的物理特性,当内部结构发生变化时,某些物理特性就会发生改变。结构建筑物的健康监测思路是:对建筑物的特性参数进行采集,经过在线处理、或发回到数据中心处理后,与健康情况下的处理结果相比较,即可得出当前建筑物所处状态是否健康。以往SHM采集数据是通过有线网络进行传输的。但随着网络规模的扩大,有线网络中传输线的成本急剧增加,供电电源困难、节点安装拆卸繁琐的缺点日益突出,无线监测成为一种趋势。 无线传感器网络(WSN)的设计必须满足 ...

Data Fusion Based KF-UI with Real Time Estimation of Dynamic Displacement and Decentralized Control [PDF]
结构健康监测与振动控制在结构安全及可靠度评估方面起着重要的作用。结构动荷载是结构设计和结构健康监测的重要基础。然而,在实际工程结构中,直接通过传感器测量结构的动荷载是非常困难的,尤其是风荷载等分布荷载的测量。因此,研究通过测量结构响应获取结构动荷载受到广大科研工作者的重视,并取得了可观的研究成果,但是现有的研究仍然存在一定的局限性。 另外,在未知激励的条件下进行系统识别(包括结构动位移识别)研究也具有非常重要的意义。结构动位移是描述结构振动特性非常必要的物理参数,许多理论方法都是先获得结构位移 ...
