Research on Swimming Training Based on Numerical Simulation and VR Technology

Computer virtual reality (VR) technology is a new technology widely used in many fields. In this study, three-dimensional numerical simulation of swimming training is carried out, and the resistance, propulsion and flow field in the swimming process are visualized through virtual reality technology, so that the swimming coach can intuitively judge whether the swimming movement is qualified and improve the skill. Numerical simulation technology analysis is the key technology of swimming training. Combined with virtual reality technology, swimming training can break the limitation of water and improve the training effect. The velocity and vortex structure of the flow field obtained from the study provide the basis for the generation mechanism of resistance and propulsion, and show good results for improving swimming training.
