| Summary: | 碩士 === 國立交通大學 === 工學院碩士在職專班精密與自動化工程學程 === 92 === The purpose of this study was to develop methods for fabricating and analyzing links, connectors, and connecting mechanism of filament wound truss structures. The production process was concerned about the strength as well as the convenience in assembling the trusses. The truss fabrication process and method began from the determination of the diameter, length, winding fiber direction, and number of layers for the links. Analytical software was used to simulate the mechanical behavior of the links under axial force. Then comparison validation was conducted on the theoretical values and actual results. For the theoretical simulation, Finite Element Method software, ANSYS, was used to construct the finite element model of the links for analysis, and two failure criteria were used to predict the tensile strength of the links. In the experiment, MTS testing machine was used to test the stretching and compressive strengths of the links. The comparison showed that the theory-based simulation when coupled with actual measurement data could predict the force endurance behavior of the links in a rational manner. The connector and connecting mechanism were improved for a number of times and when used with lightweight and high strength links, can make the assembling of the truss much faster, more accurate and convenient. The present study is a step forward to the actual application.
