Abstract

A mechanism is a mechanical system that uses certain joints to create relative movement between stiff linkages. Rolling, sliding, pin, hinge, liquid, and other joints are often used. Because of their nonlinear frictional behaviour, these joints make it challenging to regulate micro- and nanopositioning in mechanisms with great accuracy. Disadvantages like backlash and friction in the mechanism need to be addressed in order to achieve a high degree of resolution and accuracy. Flexible parts like flexural beams and hinges are used in place of these mechanical connections, providing advantages like smooth and frictionless displacement. A single DOF flexural stage, sometimes referred to as a parasitic error, is made using simple building materials like flexural hinges and beams. This stage offers little resistance to motion in the desired direction and maximum resistance in the orthogonal. The Double Flexural Mechanism (DFM), a type of beam building element, produces analytically zero parasitic error displacement with undetectable rotation of the displacement stage. This research covers experimental verification, system characterization, the design and development of DFM, as well as its mechatronic link to the dSPACE DS1104 Controller. Through static and dynamic studies, many performance characteristics like as stiffness, natural frequency, and damping factor are experimentally determined. Additionally, a cutting-edge position algorithm is created and used to the mechanism, which removes the need for expensive sensors and produces precision of 30 microns at 6.1 mm/s.
