黄河防汛抢险技术虚拟试验场构建技术研究OA

The flood control and rescue technology of test base in the Yellow River is composed of"virtual"and"real"parts.The virtual platform is the digital twin of the physical test base.With the goal of building the Yellow River flood control and rescue technology virtual test base,the site structure is decomposed based on the overall layout plan.For seven sets of modular components,the 3D model is driven by solid size parameters,and the polygonal model and curved model are respectively built for different components according to the additional materials;Use tools such as C4D to build the 3D scene;The Navier-Stokes equations are solved by the Smoothed Particle Hydrodynamics(SPH)method,and the fluid particles and grids are generated in the pool based on Realflow sortware,and the particle hydraulic elements are obtained in two dimensions of time and space;Use Octane render to render 3D scene and fluid mesh;Finally,a virtual scene with highly realism and reliability was constructed.
