The use of virtual simulators in training has been gaining attention in recent years. From this perspective, advances and cost reductions in technology make immersive virtual reality a more engaging platform to experiment with the activities to be learned, facilitating concepts and operation learning. Anyhow, to guarantee that the virtual experience can be transferred to real-world activities, it is necessary that the training system ensures a realistic behavior in terms of reaction to the learner’s actions; this can only be achieved through a faithful simulation of the phenomena and of the functioning of the equipment suitably integrated with the Virtual Reality environment. To this aim, this paper describes a methodology for the integration of a dynamic model of industrial equipment with an immersive Virtual Reality simulator for the training of operators.
