This paper proposes a dual-mode modeling technology based on software- Computer Aided X Alliance (CAXA), and verifies the method with a belt conveyor as an example. The purpose of dual-mode modeling technology integrating innovation design pattern and engineering design pattern is to achieve a fusion between open design and accuracy design technology. Dual-mode modeling approach breaks single thought constraint owned by traditional parametric modeling, which has a strict relationship like father and son between part elements. By means of design example, this paper described the help that unique three-dimensional sphere functions only owned by CAXA give the solid modeling. This paper took belt conveyor for an example, introduced dual-mode modeling process and verified this approach.

With the demand on integrated construction of large scale LNG facilities in non-slide way zone at marine construction site, finite element analysis with parametric modeling technology (ANSYS-APDL) are conducted to simulate nonlinear relationship of basement and the state of foundation settlement at the construction stage. Structural analysis models are simplified from 3D architecture models of build order in building information modeling (BIM) system through MATLAB interface development. Unfavorable settlement effects are examined by detailed analysis cases studying. The prediction results can guide installation and temporary reinforcement measures of large scale structures.

Faced with the increasingly fierce market competition, manufacturing needs to shorten the product development cycle, and Additive Manufacturing will be widely applied as it can greatly shorten the product development cycle. After years of development, Additive Manufacturing will face a good market prospect as the manufacturing equipment, materials and process have become more and more mature. However, modeling technology is always the bottleneck problem of the product development process, as it occupies most time of the product development. The aim of the paper is to illustrate how to improve the efficiency of modeling for additive manufacturing. As the the application conditions of Additive Manufacturing continues to be mature , rapid modeling technologies will be discussed in the paper, including hierarchical modeling ,standardized modeling and parametric modeling technology, which will lay the foundation for rapid modeling of product development. The method of comparative test verification is adopted in the paper, and the results show that rapid modeling technologies discussed in the paper can fully improve the efficiency of modeling for Additive Manufacturing.

With the assistance of parametric technology, micro-architecture design based on weaving is easier to express and apply accurately. This paper analyzes the parametric modeling principle of weaving in micro-architecture design, and studies the parametric modeling technology of weaving motif micro-architecture with the example of micro-architecture shared station design. The conclusion shows that the core parameter model of micro-architecture with weaving motif includes parallel line weaving micro-architecture, gradual weaving micro-architecture and random weaving micro-architecture, each of which has its own corresponding micro-architecture function, and the parameterization technology has an obvious optimization effect on the micro-architecture's envelope shape and manufacturing. Based on this, the combination of micro-architecture and advanced modeling technology is preliminary discussed to promote the design of micro-architecture to be more efficient, ecological and innovative, to promote the upgrading of micro-building manufacturing engineering.

Aerodynamic design of launch vehicle is facing combinatorial explosion problem caused by modular design. In order to get basic feasible solution from huge design space, the efficiency of design and simulation must be improved. In this paper, a parametric modeling and simulation method is proposed, which is based on CAD/CFD tools. Firstly, the design Variables of the launch vehicle are divided into three categories: size parameters, configuration parameters and mesh parameters. Secondly, parametric geometry model, including size and configuration parameters, is obtained by secondary development of Pro/ENGINEER. Thirdly, parametric mesh files for CFD are generated by implementing CFD-GEOM with scripts written in Python. By specifying boundary conditions through command stream of GAMBIT, FLUENT software will run automatically to calculate the aerodynamic performance of the launch vehicle. Finally, a graphical user interface (GUI) is developed using VC++6.0. With this system, the integration of CAD/CFD application is achieved. As long as designers enter certain design parameters in the GUI, they will quickly achieve 3D geometry model and aerodynamic performance of the launch vehicle. Application examples show that, this system can significantly improve the efficiency of aerodynamic design of the launch vehicle, and the data error between simulation and experiment is less than 10%, which is acceptable.
