A Simple Generation Technique of Complex Geotechnical Computational Model

Given that FLAC3D (a geotechnical calculation software) is difficult to use for building large, complex, and three-dimensional mining models, the current study proposes a fast and a convenient modeling technique that combines the unique advantages of FLAC3D in numerical calculation and those of SURPAC (a mine design software) in three-dimensional modeling, and the interface program was compiled. First, the relationship between the FLAC3D and the SURPAC unit data was examined, and the transformation technique between the data was given. Then, the interface program that transforms the mine design model to calculate the model was compiled using FORTRAN, and the specific steps of the program implementation were described using a large iron and copper mine modeling example. The results show that the proposed transformation technique and its corresponding interface program transformed the SURPAC model into the FLAC3D model, which expedited FLAC3D modeling, verified the validity and feasibility of the transformation technique, and expanded the application spaces of FLAC3D and SURPAC.

The Relationship

The relationship between the 3D structure of the open-cell carbon foams and its properties is particularly difficult to establish without a “true” representation of the foam. The complex structure of graphitized carbon foams is difficult to capture using one or even two-dimensional models. Several attempts have been made to model carbon foams as cellular materials. However, the regular models cannot account for the complex interaction between the pores in the true foam. The present paper characterizes the structure of “true” foam and links it to its thermal and mechanical properties.

The Relationship

This paper mainly studies modeling and recognition of 3D English words’ images. With the development of secondary modeling, segmentation and recognition theories and the application of evolution computation in 3D modeling and recognition, this paper analyzes the issues of parameter fitting in the 3D model, multi-object scene segmentation and parts recognition aiming at the 3D data features in the English words. The 3D model is used as the primitives part to model and segment the scenes and the group parallel evolution and the relationship matching theories are introduced into the 3D modeling and recognition to deeply identify the rare English words’ images. The paper searches for a practical and efficient three-dimensional modeling and identification scheme.

Contour Surface

Working profile of Globoidal indexing cam is a complex surface. 2D mechanical drawing is difficult to describe it clearly. With the development of computer technology, the 3D design software such as CATIA, Pro-E, Solidworks, UG/NX, the solid and surface function of them make productions more excellent. Globoidal indexing cam profile equations firstly was studied, the geometric size of the globoidal indexing cam mechanism was calculate, and then use MATLAB to calculate the globoidal indexing cam contour surface 3D coordinates of points, finally completed the three-dimensional modeling of globoidal indexing cam in CATIA.

Set Up

It is usually a time-consuming process to set up three-dimensinal(3D) model of mechanical components with complex surface. In order to solve the problem, this paper adopts consumer cameras and the technique of digital close range photogrammetry ( DCRP ) to establish 3D model, and export the data to 3D mechanical design software (SolidWorks) for further simulation and reconstruction. This method has been proved very effective in practise.
