Abstract :
This paper focuses on the development of a new high precision micropositioning device that is capable of traveling in translational and rotational motions. The device was modeled via the application of flexural cantilever structure to harness the precision and accuracy in implementing the positioning routine. This attribute is paramount to enable further manipulation procedures such as grasping, injecting, mounting, assembly and machining to be performed. A new hinge configuration was specifically designed to provide the micropositioner platform with 3-degree of freedom motion capability (x-y-thetas). Furthermore, a new approach in delivering the actuated motion has been devised via the utilization of slander beam profile acting in pressing mode which is critical in improving the performance of the device particularly in extending its capability to operate within high frequency range. The modeling procedure was realized via the combination of Pseudo Rigid Body Model (PRBM) and Finite Element Analysis (FEA). Analysis was performed within simulation environment to observe and verify the performance of the proposed model under various modes of motions. The analyses authenticate the capacity of the micropositioner to demonstrate high accuracy and fidelity motion.
