For the compliant translational joint, parameters of the CT joint are investigates via the cantilever beam theory. Stiffness ratio for the joint are also investigated. In addition, an innovative expression via graphs for the topology of the CT joint is established. By using the graph theory, new CT joints can be enumerated. For the compliant revolute joint, a literature survey for the CR joint is conducted. Then, factors that affect the benchmarking indexes are investigated. An innovative design of the CR joint is then proposed. Optimization as well as finite element analysis then performed in order to validate the design. |
