張拉整體基本形體穩(wěn)定構(gòu)型理論
[Abstract]:In this paper, unified geometric parameters are used to describe one-dimensional, two-dimensional and three-dimensional spatial dimension structures, and the seamless evolution of different dimension structures is realized by changing geometric parameters. Based on the geometric parameters and fractal parameters of the basic body structure, the theory of stable configuration of the tensioned whole body is constructed by using the node force balance method. The mathematical analysis models of main fractal parameters and auxiliary fractal parameters, spatial position of components and structural geometric parameters are established. The mapping relationship between the main fractal parameters and the auxiliary fractal parameters to construct the basic unit structure of self-stress stability is established. The functional relationship between the force density of each component under the condition of self-stress stability is obtained. The Matlab program is written by combining the joint generalized coordinates with the connection matrix of the component, the internal force density of the component, and the force balance of the system. By inputting the geometric parameters of the basic body envelope and the main fractal parameters, the program can automatically complete the auxiliary fractal parameter determination, the vector calculation of all components and their spatial arrangement, and realize the automatic configuration of the basic unit of self-stress stability. The self-stress stable structures constructed by different fractal parameters are analyzed and compared, and the functional relationship and changing trend between fractal parameters and structural geometric parameters, force density and auxiliary body parameters are given.
