[0079] Image 6 Schematic diagram showing the geometry topology for an icosahedral aggregate geometry that realizes the interface geometry of equal thickness around its surface. Firstly, the icosahedral aggregate is divided into 20 tetrahedral units using commercial software (such as ANSYS, ABAQUS, etc.), and then according to the specific implementation steps introduced above, the Minkowsky summation mechanism is geometrically realized to construct its surface surroundings, etc. The geometric topology of the thickness interface, that is, the icosahedral aggregate is used as the basic unit body, Image 6 The sphere shown is an extended unit body, the radius of the sphere is set as the interface thickness, and the center of the sphere is located on the surface of the basic unit body. According to formula (1), the Minkowsky summation mechanism of the basic unit body and the extended unit body is geometrically expressed as Image 6 The trajectory of the extended sphere rolling a...
