Digital Twins for Heavy Machinery

 Again, a means of creating a 'digital twin', or simulation, to prototype, operate in context or design some 'thing'.  Here the object is heavy machinery.   But could also be a combination of machinery and process and usage context.   A way to integrate simulation with data, physical systems and context goals.  Note mentioned here another way to look at this, as 'Hardware in the Loop' or HIL.  A method we frequently used.  

Rapid Prototyping: Testing Heavy Equipment in Software


Researchers at the Fraunhofer Institute for Industrial Mathematics in Germany have developed a hardware-in-the-loop (HiL) platform that aims to make machine development faster and more affordable through the use of software simulation. Said Fraunhofer's Christian Salzig, "Our HiL simulator allows us to test heavy equipment of all kinds, including a variety of crane types and concrete pumps. This allows us to help optimize prototypes." The process involves reproducing the machine to be tested as a software model, incorporating its technical specifications and the physical laws of mechanics, hydraulics, and electronics as mathematical equations. The simulator with the digital twin is then connected to the electronic control units that control machine operation, with the machine's movements reproduced on an animated, three-dimensional display. The software can simulate the precision of operations between the machine and the control unit, as well as malfunctions and critical borderline situations.
