    摘要: There is provided an analysis method whereby, when a proposed plan for deforming a resin molded article (for example, a countermeasure plan for warpage) is created and designed, it is possible to create a more effective proposed plan in a short time and in which computation cost is considerably reduced. In an deformation state analysis method of analyzing, for a resin molded article to be deformed, a deformation state of the resin molded article by optimizing an objective function under a prescribed restraint condition and a prescribed limiting condition, using a topology optimization method dividing the resin molded article into micro regions, the prescribed restraint condition is a trend of the amount of deformation of the resin molded article, the prescribed limiting condition is a contribution rate expressing an extent to which deformation of each micro region contributes to deformation of the resin molded article, and in the optimization of the objective function optimization is performed so as to minimize rigidity of the resin molded article.

    摘要: The subject invention provides a method of designing disc brake pads. The method includes the step of developing a finite element model of a precursor brake pad design using dimensional and material property information of its backing plate and friction pad to perform a normal mode analysis of the precursor brake pad design. The method proceeds with the step of performing the normal mode analysis using the finite element model to determine whether there is an area on the friction surface having an excitation amplitude that is greater than a threshold value of amplitude. If an area having an excitation amplitude greater than the threshold value is determined, the precursor brake pad design is modified to provide a brake pad design having a relieved portion in the area.

    摘要: Surface processed data is formed to which a grain having a good outward appearance is applied without generating little distortion on the surface of a product by requiring no enormous data process.Surface form data as an object to which a grain is applied is inputted to a data input part 11. A plane polygon forming part 14 projects a borderline of the surface form data on an x-y plane and changes the borderline to poly-lines to form a two-dimensional polygon mesh having the borderline as an outer edge. A three-dimensional polygon forming part 15 connects together intersections of straight lines extending to a z-axis direction from apexes of the polygon mesh and the original surface form data to obtain a three-dimensional polygon mesh and further make the mesh uniform. A grain forming part 17 obtains an amount of displacement from texture data corresponding to the apex of the three-dimensional polygon mesh through a texture model formed and deformed in a texture model deforming part 16 to set polygon data obtained by connecting together the apexes respectively displaced in normal directions as the surface processed data.

    摘要: The invention provides an apparatus and methods for performing process simulation and structural analysis using a hybrid model. For example, a method of the invention automatically defines a hybrid solution domain by dividing a representation of a plastic component or mold cavity into two portions—a portion in which a simplified analysis may be conducted, and a portion in which a more complex analysis is required. The method may use as input any form of CAD data that describes the surface of a component or mold. Furthermore, the invention provides methods for simulating fluid flow within a mold cavity by automatically creating a hybrid solution domain, automatically discretizing the domain, and solving for the distribution of process variables within the solution domain.
