Abstract
This thesis studies the design of compliant revolute joint (CR joint). First, to realize the pros and cons of various CR joints, a literature survey for the CR joint is conducted. The design directions are established by the results of literature review. Then, factors that affect the benchmarking indexes are investigated by finite element analysis and mechanics of materials. An innovative design of the CR joint is then proposed. To enhance the range of motion and improve precision, structural optimization is performed via CAE’s optimization module. Finally, experiments on the rigidity are conducted and results are compared to the results of finite element analysis. According to the results of simulation and experiment, it is concluded that the benchmarking indexes of new design are much better than any other CR joints.
