The invention discloses a
virtual test three-dimensional material model generation method, device and
system, and belongs to the technical field of intelligent test and
simulation of
engineering machinery. Comprising the steps that the geometric shape of a material
pile is constructed based on the NURBS curved surface technology, the shape of the material
pile is regulated and controlled, and a preliminary material
pile NURBS curved surface is obtained; converting the curved surface into a closed triangular
mesh model; performing rendering
processing on the triangular
mesh model, adopting a texture-geometry
adaptive matching algorithm to solve the problem of texture
distortion of a complex curved surface, and simulating material performance of different physical states through a multi-scale parameter collaborative optimization strategy; performing
dynamic simulation and
interactive processing to generate a final material pile model; inputting the final material pile model into a target
virtual test platform, and performing
virtual test application; according to the method, the problems of single material pile model form, material
distortion, lack of dynamic interaction and low tool integration degree in the prior art are solved, and the precision and efficiency of virtual testing are remarkably improved.
