Abstract
This thesis aims to analyze the current design of the activation mechanism, and attain further insight into the functioning and efficiency of this mechanism. Moreover, provide advice for improvements and design of a final prototype activation mechanism when keeping efficiency, reliability, maintainability and robustness in mind. Foremost, the design is structurally analyzed using manual computations and finite element method studies. The components are validated for robustness, strength, fatigue, and wear. The functionality of the activation is analyzed for its general working principle, its maintainability and a failure mode and effect analysis study is conducted to verify safety. Finally, for the analysis of efficiency, the losses in the bearings are computed, and a testing plan is drawn up for empirical validation of the energy losses of the system. The results of the research show that all components of the activation mechanism are sufficiently strong with a significant margin, which is not usual for designing such mechanisms. The extra margin of strength is however useful to facilitate future upgrades and changes to the testing setup. The ratcheting function and the components which support this need to be tested for functionality empirically. The testing setup requires safety features to ensure the safety of humans and the testing setup. The losses are generated in principle by the bearings in the mechanism, and expected to be 0.177W. Finally, a testing plan is created
