Real Time Digital Twin based Structural Health Monitoring

This video describes how to model, setup and run a Digital Twin for Structural Health Monitoring of a real physical offshore crane. The digital twin is simulating physical crane operations based on outputs from the crane sensors sent from an IoT gateway to a cloud solution. The cloud sensor data is filtered and read by a FEDEM digital twin that replicates the physical crane motions. The simulation is then running real time FE analysis of the crane during offshore operations. The presentation shows temporary results from an ongoing EC project called Arrowhead Tools,

Hi, I don't know if you see this comment since your last videos 8 months ago but I'd like to thanks to your videos especially FEAinME. I hope you'll continue to share more videos, these videos are so valuable for people who want to develop his/her knowledge. Thank you so much again.

Thanks for your nice and inspiring words. I have changed my position at the university and thats why I haven’t made new FEAinME videos. However, I am now preparing a new course called Digital Twin Technology (for Structural Health Monitoring) and will make new videos demonstrating various technologies and methods

@@FedemDigitalTwins I will be waiting for your new videos, thank you again :)

Thank you for the video. Can we use a revit model instead of a cad model (wanted to do the shm for a building against an earthquake)

Hello,
How the data from the sensors mounted on the physical model is being implied on the digital model. Would be really helpful of you could help.
Thanks in advance

The sensors on the physical crane are not replicated on the digital twin. They are standard Palfinger instruments not directly applicable as input drivers on the crane. There are ex. two angular sensor outputs that I translates to equivalent tilt cylinder strokes (driven actuators in the FEDEM model). The cylinders are modelled according to the cylinder property specs to get the correct input loads and stiffness. The overall boom length is measured on the physical crane and these are translated to individual telescopic cylinder strokes. These is also one measurement of the crane slewing angle and vertical wave motions that are used directly as input to the crane simulation (after low pass filtering in Python)

Appreciate your time, but can we simulate the exact working condition on the digital model? For example if we are creating a digital twin of an elevator door , can the sliding movement of the physical elevator door be represented in the digital model aswell?

@@mrrohan6396 Shure, are you thinking of a kinematic, rigid body or a flexible body dynamic analysis? In FEDEM I can run a real time flexible body analysis (FEA) since the software uses CMS model reduction (super elemements) It could be a perfect solver for your elevator door!

@@FedemDigitalTwins If I give a input of say 10mm sliding movement of the elevator, can this be achieved in software? And can I vary the distance of the sliding movement?
