Modeling and simulation of the Michigan Aerospace autonomous satellite docking system II

The scope of the analysis was to determine the capability of the Michigan Aerospace Corporation (MAC) Autonomous Docking Satellite System II (referred to as 'ASDS' for the remainder of this paper), and to develop and mature the concept. The integrated system model included detailed subsystem models. A cable model was developed from the test data that resulted in good correlation. A high fidelity subsystem model of the cam resistance force was modeled. The integrated system model also includes contact definitions, final latching/locking definition, and various sensors. Over 3,000 cases were analyzed to identify areas where the MAC docking concept can be improved. Sensitivity and Monte Carlo studies were completed to understand the mechanism’s capture capability, determine subsystem requirements, and evolve the design for improved performance.
