[Abstract]:Based on the deployable truss antenna as the research object, discusses the implementation method of the deployable antenna parameters modeling and related technology. Developed the I-DEAS deployable antenna parameters modeling based on the software, the software can quickly establish the 3D model of deployable antenna. The specific work is as follows: first, starting with from the modeling technology of the parameters, given the overall design of the parametric modeling platform, introduces the basic process of modeling framework and parameters modeling platform. The paper discusses the two developing function of I-DEAS software, this article introduces the method to realize parametric and parametric assembly using I-DEAS. Introduces the CAD/CAE integrated technology based on database, and discusses the transfer mode between CAD and CAE data. SQL Server database system is established based on comprehensive design The shared database platform, mainly for the key parameters of information storage of deployable antenna, in order to achieve the design and analysis module of data transmission and data exchange. Secondly, the deployable truss antenna as an example, the design of truss antenna truss and cable net structure, the size parameters and related parts of the calculation are determined. Antenna truss, cable network topology, presents the calculation method of two key node coordinates, geometric model of truss antenna truss is established according to the key to calculate the coordinates of the nodes. The proposed scheme consists of a basic deployable truss antenna unit, and the single module and multi module truss structure kinematics analysis complete truss joint, support rod, design structure model of device and the locking mechanism. The parametric design method of truss antenna truss and cable network, and establish a framework The parametric model of deployable antenna. Finally, based on the deployable antenna parametric modeling software "has a perimeter truss antenna with radial rib antenna parametric modeling function, completed the development and data frame type antenna parametric modeling program storage. Combined with the modeling process of frame the antenna parameters, introduces the parametric modeling software interface and specific functions, parametric modeling function of the software is verified through an example. By using the parametric modeling software can quickly establish the parametric model of deployable antenna, and provide a theoretical basis and reference for the design of the antenna.
