Development of Parallel Mechanism for Small Satellite Launching Emulation

Abstract

This thesis presents the development and analysis of a six-degree-of-freedom (6DOF) CubeSat shaker system designed to enhance the testing procedures for CubeSats by simulating the complex and dynamic conditions experienced during rocket launches. Traditional testing methods, primarily utilizing uniaxial shakers, fall short in accurately replicating the multidirectional dynamic forces encountered in space. The proposed 6DOF shaker aims to address this limitation by providing a more realistic simulation environment that includes all three translational and rotational axes, thereby offering a comprehensive assessment of the CubeSat's structural integrity and operational reliability under simulated space launch conditions. The research involves a detailed design methodology utilizing advanced engineering software for simulations, including modal analysis and random vibration analysis, to validate the system's effectiveness in replicating the required dynamic conditions. The design process is supported by extensive theoretical analysis and practical considerations in material selection, system integration, and manufacturability. Key challenges addressed include technical issues related to system dynamics, software integration for real-time simulation control, budget constraints, and potential supply chain delays. The thesis provides a critical examination of these challenges with strategic mitigation strategies to ensure the project's success. The system's development is iterative, with continuous refinements based on simulation results and experimental feedback to optimize the design. The 6DOF shaker system not only stands to benefit the field of CubeSat testing but also has broader applications in industries such as automotive and military equipment testing, where accurate replication of operational environments is crucial. This work lays the groundwork for future innovations in multi-axis dynamic testing systems, potentially revolutionizing how structural tests are conducted across various engineering fields.
