Modeling of Shotcrete Application for Use in a Real-Time Training Simulator

This article describes how simulators can provide significant advantages for training operators of concrete spraying machinery. These advantages include economic savings, the practical absence of safety risks, and environmental and educational benefits. The main challenge in developing a real-time training simulator for concrete spraying machinery lies in the modeling of shotcrete application. A novel method that models and simulates in real time is presented in this article. The three main factors that influence shotcrete sprayability are adhesion, cohesion, and rebound. Furthermore, the method presented makes it possible to spray onto additional supporting elements, which is a typical shotcrete application. The proposed method considers a wet-mix thick flow spraying process and is based on experiments that were run with a real concrete spraying machine and complemented by expert advice. A method was developed and evaluated in this paper using a user-centered methodology that resulted in realistic shotcrete application modeling that meets the needs for training machinery operators.
