Numerical co-simulation in industry 4.0 – Creating digital twin of belt transmission with NX and Matlab

The subject matter of the research described in the paper is the procedure of creating a digital twin of a mechanism under consideration, representing the dynamic features of the latter. There was suggested a solution based on the use of popular CAE tools – the NX and MATLAB software. A model was built to show the elasticity of the belt and its contact with the transmission pulleys, which accurately reflects the mechanical processes occurring during the operation of the drive system. It was investigated how data obtained in the simulation can be integrated into the flow of information between various digital environments and industrial devices – e.g. within the Industrial Internet of Things (IIoT). The experiments were conducted with the use of the examined solution, and their promising results and conclusions drawn from them are described in the present publication.
