碩士 / 國立虎尾科技大學 / 動力機械工程研究所 / 94 / The purpose of this paper is to carry out the design and manufacture of jet propulsion mechanisms for bionic jellyfishes. Firstly, the design constraints and requirements are specified according to the characteristics of jellyfishes and existing designs. Then, the atlas of feasible mechanisms is synthesized based on the methodology of creative design. Moreover, two better choices from the atlas are selected to perform the rigid-body and compliant mechanism designs. The detailed works of rigid-body mechanisms are performed, including dimension synthesis and kinematic analysis. Then, one of the rigid-body mechanisms is transformed to its pseudo-rigid-body model for carrying out the strength design. Furthermore, the force-deformation analysis is conducted by ANSYS software to obtain the relationship between forces, deformations, and angles of twist. Finally, all the designs are validated by computer simulation using ADAMS software. In addition, the feasibility of the design is verified by conducting a prototype testing. The simulation results show that the contraction and relaxation motion of the designed mechanism agrees fairly with a real jellyfish.
