The following topics illustrate capabilities that were subject of active development.
Piezo module documentation
📝 A major update of the piezo module documentation has been performed.
The revision takes advantage of our recent overhaul of documentation tools to provide a better view of available capabilities.
The emphasis has been put on tutorial and examples throughout the document. A total of 28 tutorial scripts covering most aspects of the toolbox have been written!
In particular the following sections have been added with theory and tutorials on:
👉 General sensors and actuators definition
👉 Automated and manual methods for meshing plates with piezoelectric patches
👉 Model reduction and I/O state-space models
- with imposed displacement/acceleration/voltage conditions
- creating a state-space model from a Craig-Bampton reduced model
💡 Each tutorial is presented as a stepped analysis script from model definition to simulation post-treatment capture reproducing the provided illustrations. Dedicated display styles have been defined and made available to provide quality automated reporting.
All tutorials are eventually available in a GUI for easy browsing, with links to the associated documentation pages.
Parametric Experimental Modal Analysis
🕓 SDTools has performed many parametric EMA studies in the recent years.
We have converged toward a standardized strategy that tackles all these analyses using the same framework.
💡 This framework relies on two steps:
1- Transfers corresponding to the first system configuration are loaded and EMA is performed manually.
2- Automatic optimizations of poles from current configuration to the next are sequentially performed.
This algorithm has been applied to analyze
👉 Modal property dispersion in batches of similar components
👉 Mode tracking with temperature
👉 Mode tracking with excitation amplitude level
👉 Other currently ongoing projects…
▶ The video illustrates this framework applied to the GARTEUR test case, where the system configuration depends on the temperature parameter.
