RISSynthesis of Compliant Mechanisms for Path Generation using Genetic Algorithm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper is described a procedure to synthesize the optimal topology, shape, and size of compliant continua for a given nonlinear output path. The path is prescribed using a finite number ...
An Adaptive Material Mask Overlay Method: Modifications and Investigations on Binary, Well Connected Robust Compliant Continua
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The material mask overlay strategy employs negative masks to create material voids within the design region to synthesize perfectly binary (0-1), well connected continua. Previous implementations ...
A Material-Mask Overlay Strategy for Continuum Topology Optimization of Compliant Mechanisms Using Honeycomb Discretization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes novel honeycomb tessellation and material-mask overlay methods to obtain optimal single-material compliant topologies free from checkerboard and point-flexure pathologies. The ...
Are Circular Shaped Masks Adequate in Adaptive Mask Overlay Topology Synthesis Method?
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Previous versions of the material mask overlay strategy (MMOS) for topology synthesis primarily employ circular masks to simulate voids within the design region. MMOS operates on the photolithographic ...
An Improved Material-Mask Overlay Strategy for Topology Optimization of Structures and Compliant Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The honeycomb-based domain representation directly yields checkerboard and point flexure free optimal solutions to various topology design problems without requiring any supplementary suppression ...
Design of Electrothermally Compliant MEMS With Hexagonal Cells Using Local Temperature and Stress Constraints
Publisher: The American Society of Mechanical Engineers (ASME)

Abstract: Initially curved frame elements are used in this paper within an optimization-based framework for the systematic synthesis of compliant mechanisms (CMs) that can trace nonlinear paths. These ...
Systematic Synthesis of Large Displacement Contact-Aided Monolithic Compliant Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A single-piece contact-aided compliant mechanism (CCM) deforms to use one or many contact interactions to deliver the prescribed intricate input–output functionality. We present an automated synthesis ...
How to Choose From a Synthesized Set of Path-Generating Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Partially compliant mechanisms inherit the attributes of fully compliant and rigid-body linkages and offer simpler, compact design alternatives to accomplish complex kinematic tasks such as tracing ...
