Expansion joints are non-standard devices whose shape and parameters could vary with temperature, pressure, displacement and cycle life, so it's drawing work is very burdensome. Expansion joint industry is badly in need a set of accurate, reliable and stong practical professional graphics software. Therefore this paper carried out targeted secondary development of the software on the basis of digestion and absorption of SolidWorks2010 so as to meet the urgent needs of expansion joints industry. The structure of most parts of bellows expansion joints is not complex, and their geometry are relatively simple and fixed, so it is very suitable for parametric modeling method.

According to the rules of six typical spherical reticulated shell nodes, the modeling method and the design macro program is developed for the nodes and the bars of six typical semi-outdoor spherical reticulated shell structures by using the ANSYS parametric design language APDL, so as to achieve the parametric design of six typical semi-outdoor spherical reticulated shells. The modeling design examples indicate that it's convenient to achieve the parametric modeling and design of semi-outdoor shell with given span S, rise high F, number of hoop symmetry areas kn, radial node cycles of whole structure nx and the upper removed laps ns, which provides big convenience for the force analysis and the optimization scheme comparison of semi-outdoor spherical lattice shells with varied types and geometric parameters.

Composite Microstructure

A method of parametric modeling composite microstructure is proposed. It can be used for composite microstructure virtual testing and optimization procedure. Considering the fiber random distribution features of composite microstructure and the flaw distribution in the fibers, a three dimensional parametric model has been built in this paper. Then, the sizes of the composite representative volume element (RVE) generated by the method are determined by moving-window function method. These models are close to reality and can be used for further virtual testing. Finally, numerical experiment is presented by the secondary development of the finite element packages (ABAQUS) via Python language programming to verify the proposed method. The following conclusions are obtained: (i) fiber volume fraction of the composite structure model reaches 65% by the modeling method, which meets the majority engineering demands; (ii) stress distribution feature of RVE generated by using moving-window function method coincides with general prediction.

The Finite Element Model

In this study, a method called “house-building frame modeling” based on the APDL language is introduced firstly, and the finite element model of the milling distortion analysis is established for a platform structure with 192 frames by the method, and the prediction analysis of the milling distortion under different milling conditions is carried out, by means of 3-D finite element simulation technology. Comparing the simulation results and the measurement ones of the milling distortion, the proposed model is modified; the modeling method and prediction method are proved to be effective.
