"The pseudo-rigid-body model (PRBM) concept, developed for the analysis and design of large-deflection flexible members, has proved over time to be a simple, efficient and accurate tool for the synthesis, analysis and design of compliant mechanisms. This dissertation investigates a variety of compliant mechanism analysis and design problems using the PRBM concept and assists in further advancement of the implementation of the PRBMs. The dissertation begins with the development of a PRBM for a fixed-guided compliant beam with one inflection point in the deformed state. This research investigation advances the concept of characteristic deflection domain to a new synthesis framework for the design of fully-compliant mechanisms containing fixed-guided segments with an inflection point. The dissertation then formalizes a new approach for the evaluation of mechanical advantage of compliant mechanisms. In order to extend the approach towards synthesis and design of compliant mechanisms with higher mechanical advantage, the dissertation revisits the synthesis with compliance method of compliant mechanism design and provides an implementation strategy. A new method to determine an appropriate PRBM is presented. The method also allows determination of the expected static mode shape(s) of a given compliant mechanism structural configuration. Finally, the dissertation provides experimental results to validate the simplicity, accuracy, efficiency and applicability of the PRBM concept towards the synthesis, analysis and design of compliant segments and compliant mechanisms. The test setup design utilized for the experimental investigations may be found in the addendum to this dissertation."--Abstract, page iii.
