Zusammenfassung: | The invention provides a finite element modeling method for a human head for researching collision damage of an automobile. The finite element modeling method comprises the following steps: firstly, carrying out tomography and nuclear magnetic resonance scanning on the human head to obtain a tomography scanning image; secondly, importing the tomography scanning image into Mimics, and preprocessing the tomography scanning image to obtain point cloud data; thirdly, importing the point cloud data obtained in the second step into Geomagic Studio, and carrying out parameterized processing on the point cloud data to generate curved surfaces; detecting the generated curved surfaces, and fitting all the curved surfaces by using cubic Bezeir curves to obtain a three-dimensional geometrical model; fourthly, importing the three-dimensional geometrical model into HyperMesh for dividing meshes, setting the type of a unit body into a linear tetrahedral unit and optimizing local grids to obtain a three-dimensional solid mod |
