"Compliant mechanisms is one of the emerging researches today. Compliant mechanisms derive their some or all of their mobility from their flexible members. Fewer part count, no necessary lubrication, lesser assembly times and low production cost are just a few advantages of compliant mechanisms. Historically, large non-linear deflections make the analysis and synthesis of compliant mechanisms difficult, thereby restricting their applications to simple designs. Pseudo-rigid-body models (PRBMs) serve as an efficient tool for the analysis and synthesis of compliant mechanisms.

This work discusses an efficient method for the analysis of a fixed-guided compliant beam with one inflection point, subjected to beam end load or displacement boundary conditions, or a combination thereof. To enable this, such a beam is modeled as a pair of well-established pseudo-rigid-body models (PRBMs) for fixed-free compliant beam segments. The new stiffness coefficient equation is discussed and is applied to the above mentioned method for more accurate results. Parallel modules have proven their merit with enormous applications in the field of Micro-Electro-Mechanical Systems (MEMS). A synthesis method for a simple parallel module is developed in this work. Synthesis of a fixed-guided segment when energy specified is presented. Parametrization of pseudo-rigid-body parameters for a fixed-guided beam is developed, this will serve as simple tool that could be utilized for synthesis of compliant mechanisms. A deflection domain concept is proposed, and the deflection domain for fixed-free and fixed-guided segments are generated. Finally, an equation is developed to assist the user with the selection of the third boundary condition in a more realistic manner"--Abstract, page iii.
