Abstract:

Based on the analysis of virtual reality\|oriented hydraulic turbine system, the problem of time delay in conventional collision of various hydraulic structures under different working conditions was solved by using the method of decomposing collision bounding box. Particle boundary computation was conducted by the method of polygonal boundary construction to realize the collision between particle system and hydraulic structure, which produces a verisimilar effect of flow rebound. Decomposition of bounding box through surface reconstruction and collision test of particle boundary structure were carried out on hydraulic turbine blades, and a proper equilibrium point between running speed and fidelity was found out through tests. The simulated effect of the stable operation of hydraulic turbine underwater was realized.

Key words: virtual reality, hydraulic turbine, collision bounding box, particle boundary
