- SDT parametric EMA video showcase ➡️ Temperature-dependent MIMO transfers 🌡
Following up on previous post presenting our two-step standardized strategy to tackle parametric EMA, this one illustrates its implementation where the varying parameter is the temperature. 📝 The data is part of our tutorials for parametric experimental modal analysis on the GARTEUR test case with temperature dependency. The test being… Read more: SDT parametric EMA video showcase ➡️ Temperature-dependent MIMO transfers 🌡 - Code consistency and documentation
OK, now that I have this SDT model, what can I do with it ? ❓Our interactions with SDT users have highlighted some recurring queries:– What are the data structures used in SDT? (models, deformations, transfers…)– What can I do with each one of them? (examples, tutorials, list of functions,… Read more: Code consistency and documentation - Parametric Experimental Modal Analysis
A few years ago, we collaborated with the SHM team of PIMM on Experimental Modal Analysis of a polypropylene plate as function of temperature:🤝 https://www.sdtools.com/pimm-lab-identification-of-material-property-dependency-to-temperature/ 🕓 Since then, many other parametric EMA studies have been performed. We have converged toward a standardized strategy that tackles all these analyses using the same… Read more: Parametric Experimental Modal Analysis - MDRE on spatially sparse vibration shapes
How to ease analysis of spatially sparse vibration shapes ? ❗ Vibration measurements using accelerometers may be difficult to analyze because few sensors are often available leading to spatially sparse shapes. Animations of shapes involving single-axis sensors are even more tedious to read. Indeed, one tends to interpret the displayed… Read more: MDRE on spatially sparse vibration shapes - Reduced model animation on reduced mesh through cuts (slices)
Are you suffering from slow animations with large FEM results? Do you need to navigate into huge FEM DoE where full result would be TB of data? 💡 Rather than storing full results and animating the usual skin mesh, SDTools is finding many industrial reasons to store reduced models, perform… Read more: Reduced model animation on reduced mesh through cuts (slices) - Automatic reporting
Classical off the shelves analyses in SDT (EMA, numerical modal analysis, shape correlation, …) are integrated with automated report generation. Tables, animations, pictures, text… can then be easily analyzed with main results displayed at the same time and same place with a unified formatting. 📤Default output formats are Microsoft Word… Read more: Automatic reporting - SDT-base: Navigation through multi-dimensional data with Iiplot
Data navigation is an essential feature for engineering projects, what can be done? 🔧 An efficient tool should provide an interactive and flexible display strategy, with formatting and capturing capabilities. 💡 🚀 Come Iiplot, our versatile curve navigation and signal processing tool. It is dedicated to 2D or 3D representation… Read more: SDT-base: Navigation through multi-dimensional data with Iiplot - SDT-ZParam: Mode classification using clusters
▶️ This video illustrates how to analyze large amounts of parametric modal analysis. 🚀 Modern computing and storage capabilities allow performing large design of experiments, numerically and/or experimentally. 👀 During a project, one can thus be led to analyze overwhelmingly large amounts of modal data, hundreds or even thousands of… Read more: SDT-ZParam: Mode classification using clusters - SDT-ZParam: Modal analysis DoE navigation
💡Understanding a model sensitivity to various parameters is key to controlling quality (verification and validation), assessing modelling refinement or simplification possibilities, and getting project engineering insights. 🖥️ 🔍 DoE study display strategy must thus provide a comprehensive interactivity to allow browsing the results, that can feature many indicators, and observing… Read more: SDT-ZParam: Modal analysis DoE navigation - FEM, testing and hybrid twin displays with SDT tetrahedron
♻️Refreshing of our good old logo is an occasion to illustrate SDT’s display capabilities in FEM, testing and hybrid twins handling. 💡Our logo features the first ever structure that was simulated in what was to become the SDT. It is a tetrahedron shaped truss working as a mirror support in… Read more: FEM, testing and hybrid twin displays with SDT tetrahedron - Experimental Modal Analysis using SDT dedicated GUI (dock ID)
SDT provides advanced solutions for Experimental Modal Analysis. They are integrated in the “dock Id” providing an interactive interface to perform this task:⚙️ Define pole/residue model options🌱 Initialize poles (mode frequencies and dampings)💡 Estimate residues (shapes)🔎 Check identification quality▶ Animate mode shapes🔄 Optimize modes (poles + residues)📄 Generate automated report… Read more: Experimental Modal Analysis using SDT dedicated GUI (dock ID)
