Abstract

The invention belongs to the technical field of simulation methods, and specifically relates to an interactive virtual-reality simulation method for a backwash filter. The interactive virtual-realitysimulation method comprises the following steps: S1, modeling: establishing a three-dimensional model of the backwash filter; S2, loading: loading the filter model in Unity; and S3, interactive designing and motion simulation: 1) the virtual scene of normal-flow filtration: defining the trajectory of a fluid with an iTween plugin; controlling dominance and recessiveness of an arrow indicating thetrajectory of a filtered fluid through C# script programming; and controlling the starting and stopping time of filling of a filter element with a liquid through compiling of a time controller; and 2)the virtual scene of back washing: amplifying the local effect of a filter through small map functions; defining the trajectory of a backwash fluid with the iTween plugin; controlling the movement ofa valve element and a filter element with scripts; creating backwash water and impurities; and compiling the scripts, and controlling the process of simulation with an external device. The interactive virtual-reality simulation method provided by the invention can reflect the characteristics, morphology and layout of elements in an actual scene in a realistic, vivid and accurate way.

Description

technical field [0001] The invention belongs to the technical field of simulation methods, and in particular relates to an interactive virtual reality simulation method for backwashing filters. Background technique [0002] High water-based liquid return backwash filter is widely used in the hydraulic system of fully mechanized coal mining support, used to filter the particles contained in the emulsion and realize self-cleaning, which is the key to ensure the safe and efficient production of coal mine fully mechanized mining face factor. Observe the flow state of the particle-containing liquid in the inner cavity of the return liquid backwash filter, such as migration and deposition distribution, and show the whole process of forward filtration and reverse flushing of the return liquid backwash filter. Blind spot control, quality controllability and product presentation are of great significance. [0003] In order to achieve a realistic description of the filtration state ...
