Artemis Modal Pro 8 是一款专业的操作模态分析和实验模态分析软件,这款软件基于 ARTeMIS Extractor 技术开发,软件采用了 ARTeMIS Extractor 的所有算法,对它们进行了优化,并将它们与许多新的令人兴奋的工具结合在一起,这些工具都构成了新的 ARTeMIS Modal 平台。功能强大的一体化 OMA,EMA,ODS 和 SHM 分析解决方案,这是一个友好的可用于模态测试、分析和问题解决程序,借助于软件,您可以在不控制输入的情况下进行模态分析,在不知道和/或控制输入激励的情况下进行模态分析。
该模态技术能够估计与传统已知技术相同的模态参数。模态参数是模态形状,固有频率和阻尼比。有人认为操作模态分析只是操作偏转形状 ODS 的另一个名称。不是这种情况。ARTeMIS Modal 是一种功能强大的多功能操作模态分析工具。基于对多达八种不同分析技术的并行分析,它能够生成经验证的模态参数估计,使其成为关键任务应用的自然选择。从获得专利的增强频域分解(EFDD)技术到独特的 Crystal Clear 随机子空间识别(SSI)技术,ARTeMIS Modal 使工程师能够直接从原始测量时间序列数据中获得模式形状,固有频率和阻尼比的有效估计在自然条件下的结构。该软件适用于大多数情况下,最好不要控制或测量负载。
自动模式估计。所有 SSI 技术都包括自动模式估计,用于搜索 SSI 稳定图中的稳定模式。所有测试设置的所有估计模型的所有稳定模式都包括在搜索中,并且结果是固有频率,阻尼比和高精度模式形状的模态估计。估算值以平均值和标准差表示。即使在密集间隔或重复模式和多个测试设置的情况下,SSI 的自动模式估计也起作用。
模态不确定性的估计。利用稳定图的模态估计方法通常仅存在模态参数的估计平均值。通常,稳定图显示估计模式相对于所选模型尺寸的固有频率的平均值。在这样的图中,基于平均值来搜索稳定模式。即使稳定性很明显,仍然难以评估与每种呈现模式相关的置信水平。在 SSI-UPCX 技术中,可以根据平均值周围的置信界限来可视化各个估计的不确定性。在估计 SSI-UPCX 中的全局模式时会考虑这些不确定性。
ARTeMIS Modal is a powerful software for operational modal analysis and experimental modal analysis developed by SVIBS. The software, which is open source and comes with a user-friendly graphical interface, can also be used for modal testing and modal problem solving. If you can measure the vibrations of a mechanical system, ARTeMIS Modal can also provide modes for determining the system’s dynamic parameters including natural frequencies, modes of shapes and attenuation coefficients.
ARTeMIS Modal software has been the best tool in Operational Modal Analysis ( OMA ) for two decades, and now has multidimensional methods for experimental modal analysis. This software enables the analysis of structural health monitoring and operational form deflection (ODS) and can manage several tests to increase the accuracy of the modes. Other features of the software include fast and automatic display of results, support for infinite sensors and data points, and support for various input formats.
