Conceptual design of an electronic “on the move” docking station for Ovzon satellite terminal

Sammanfattning: The following report discusses a master's thesis in the field of mechanical design within the Machine Design track at the Royal Institute of Technology. The thesis was commissioned by Svea Teknik AB and Ovzon AB. The project's starting point was an existing product in Ovzon's catalog, a satellite terminal of the T7 model. Currently, the product is sold as a "manpack," which is a portable product manually aligned with a satellite. Ovzon wished to explore the feasibility of designing a dock to quickly mount the T7 terminal. This would convert the satellite terminal into an "on the move" terminal, meaning that the satellite could automatically be directed towards a given satellite while the terminal is in motion, such as when mounted on a vehicle. The main focus of the project was concept generation to provide Ovzon with a good understanding of possible designs. The concepts were evaluated after the concept generation phase to select the most promising ones from Ovzon's perspective. The "functions means tree" tool was used for concept generation to list all possible solutions for each problem. These solutions became individual concepts within reasonable limits. The "Pughs matrix" tool was used for evaluation, assessing the concepts based on weighted parameters to provide a clear understanding of the suitability of the different concepts. The result was a dock with direct drive on both the horizontal and vertical axes. This concept did not receive the highest score in the Pughs matrix, but the client considered it to have several advantages that were difficult to capture in the matrix. In addition to designing the control system, an interface between the terminal and the dock was also developed to enable quick attachment or detachment. To ensure sufficient performance, finite element analysis was conducted on critical components, bearing calculations were performed, and the torque requirement on the motors was evaluated.
