摘要： This invention provides a shoe upper design model generating method, system and non-transitory computer readable storage media, including steps of providing a 2D mapping boundary, providing a 3D upper, performing a flattening algorithm on the 3D upper with respect to the 2D mapping boundary, constructing a 2D upper boundary, creating an upper design drawing on the 2D upper boundary, intersecting the 2D upper boundary and the 2D mapping boundary to form a 2D upper design area and mapping grids in the 2D upper design area onto grids in the 3D upper, thereby obtaining an upper design model containing the mapping relation between the 2D upper design area and the 3D upper. Accordingly, the upper pattern making time and cost can be saved, and the distortion and deformation in the process of 2D-3D conversion can be reduced, thus the completed 2D upper design drawing can be used in production process directly.

摘要： The present invention discloses a three-dimensional modeling method for thermal runaway of a lithium-ion battery under different state of charge (SOC) conditions based on a differential scanning calorimeter (DSC) experiment, comprising S1: obtaining an active material of a battery, and performing a DSC experiment to obtain a heat flow curve; S2: dividing the heat flow curve of the battery into a plurality of reaction peaks to obtain a reaction enthalpy of each peak of the battery; S3: analyzing the heat flow curve by utilizing a Kissinger equation to obtain activation energy and a pre-exponential factor; S4: fitting the heat flow curve of the material of the battery by using a genetic algorithm to obtain a reaction order of the active material of the lithium-ion battery; S5: establishing a thermal runaway model of the battery, and comparing simulation experimental results to verify the feasibility of the model; and S6: changing the SOC of the lithium-ion battery, and studying the influence of different SOC on the thermal runaway of the lithium-ion battery. The thermal runaway model established based on the DSC experiment according to the present invention can actually reproduce the thermal runaway reaction of the lithium-ion battery during the thermal runaway process and improve the accuracy of the model.

摘要： The model generation system may generate a 3D object model based on computer aided design (CAD) data describing an object. The CAD data received by the CAD conversion module 160 may contain a set of surfaces for the object. Each surface may be described by a surface equation that describes the shape of the surface in a 3D space. The model generation system may extract those surface equations from the CAD data and generate field lines and equipotential lines. The field lines may be lines that are tangent to the gradient vector field of the surface, and the equipotential lines may be lines along the surface that designate points that have the same potential within the gradient field vector. The model generation system may use the field lines and the equipotential lines to generate quadrangular tessellations for a 3D object model for the object described by the CAD data.

摘要： At least a portion of an object such as a medical implant is fabricated by a process. In the process, a porous structure, a solid structure, and an interface region directly attached to each of the porous structure and the solid structure are produced by an additive manufacturing machine using a stored output file configured for providing instructions to the additive manufacturing machine for fabricating the porous structure, the solid structure, and the interface region. The stored output file is prepared by preparing a computer-generated component file including a porous CAD volume and a solid CAD volume. Digitized radii are added to digitized struts defining digitized pores in an interface volume of porous CAD volume to mitigate stress concentrations that would otherwise result in sharp corners or notches in the fabricated object.

摘要： Methods for fabrication of articles, in particular knitted articles, using computer-controlled machines. A 3D model of the article is characterized by a 3D polygonal mesh defining a surface of the 3D model. A streamline is drawn on the 3D model, and used to define a set of isolines over the surface described by the 3D polygonal mesh. The isolines are quantized into equidistant points along their respective lengths and a cut line traversing each of the isolines is defined. Courses are defined by connecting quantization points of the isolines based on knitting rules to produce a 2D knitting map containing apexes. Apex attraction may be performed on a first portion of the 2D knitting map by decreasing a spatial distance between respective ones of the apexes. The 2D knitting map is subsequently converted to knitting instructions for a computer-controlled knitting machine.
