Abstract Although energy-based methods have advantages over the Newtonian for kinetostatic modeling, geometric nonlinearities inherent in deflections of compliant mechanisms preclude most theorems. Castigliano's first theorem and Crotti-Engesser theorem, which don't require problem being solved to be linear, are selected construct modeling framework this work. Utilization these two theorems req...

Thermal transducers, which can be regarded as thermally actuated compliant mechanisms, have found a wide range of applications, due to easy accessibility of heat source, and due to their good controllability and reliability. During the past decade topology optimization techniques have been developed as e7cient tools to design distributed compliant mechanisms and accepted by engineers. In this r...

This article presents a density-based topology optimization method for designing three-dimensional (3D) compliant mechanisms (CMs) and loadbearing structures with design-dependent pressure loading. Instead of interface-tracking techniques, the Darcy law in conjunction drainage term is employed to obtain field as function design vector. To ensure continuous transition loads evolves, flow coeffic...

Abstract We present a sequential topology and shape optimization framework to design compliant mechanisms with boundary stress constraints. In our approach, density-based method is used generate the configuration of mechanisms. Afterwards, node-based invoked obtain an exact representation. A specialized, optimality criteria-based update formulated for optimization. To avoid impractical hinges p...
