Topology Optimization of Compliant Mechanisms Using the Homogenization Method
A procedure to obtain a topology of an optimal structure considering flexibility is presented. The methodology is based on a mutual energy concept for formulation of flexibility and the homogenization method. A multi-objective optimization problem is formulated as an application of compliant mechanism design. Some examples of the design of compliant mechanisms for plane structures are presented...

Shape and Topology Optimization for Compliant Mechanisms Using Level Set- Based Parameterization Method
A new parameterization approach 1 for optimal synthesis of compliant mechanisms using level set-based shape and topology optimization approach is presented in this work. The structural free design boundary is implicitly represented by embedding into a higher-dimensional scalar function as its zero level set. The compactly supported radial basis function with a favourable smoothness is introduce...
متن کاملTopology Optimization for Large-displacement Compliant Mechanisms Using Element Free Galerkin Method
This paper presents a topology optimization approach using element-free Galerkin method (EFGM) for the optimal design of compliant mechanisms with geometrically non-linearity. Meshless method has an advantage over the finite element method(FEM) because it is more capable of handling large deformation resulted from geometrical nonlinearity. Therefore, in this paper, EFGM is employed to discretiz...
متن کاملTopology optimization of compliant mechanisms with multiple outputs
A b s t r a c t A procedure for the topology design of compliant mechanisms with multiple output requirements is presented. Two methods for handling the multiple output requirements are developed, a combined virtual load method and a weighted sum of objectives method. The problem formulations and numerical solution procedures are discussed and illustrated by design examples. The examples illust...
