摘要

振动结构的模态分析是许多工业部门设计和监测的常用技术:汽车制造，航空航天，民用结构。我们为COSMAD提供了一个无需任何测量或控制输入的运行状态软件环境。COSMAD是一个识别和检测Scilab工具箱。它涵盖了通过GUI或全自动模态识别和监控对结果进行视觉检查的模态识别。该工具箱为信号可视化、滤波和下采样、频率和阻尼随时间的跟踪、模态形状可视化、MAC计算等提供了一个完整的软件包。检测部分也是一个综合工具箱，用于故障部件的模态诊断和物理定位

COSMAD: a Scilab toolbox for output-only modal analysis and diagnosis of vibrating structures

Modal analysis of vibrating structures is a usual technique for design and monitoring in many industrial sectors: car manufacturing, aerospace, civil structures. We present COSMAD a software environment for in-operation situation without any measured or controlled input. COSMAD is an identification and detection Scilab toolbox. It covers modal identification with visual inspection of the results via a GUI or fully automated modal identification and monitoring. The toolbox offers a complete package for signal visualization, filtering and down-sampling, the tracking of frequency and damping over time, mode-shape visualization, MAC computation, etc. The detection part is also a comprehensive toolbox for modal diagnosis and physical localization of faulty components
