Design of compliant mechanisms using continuum topology optimization: A review
TL;DR: A survey of the state-of-the-art design advances in this research area over the past 20 years is presented and can be helpful to those engaged in the topology optimization of compliant mechanisms who desire to be apprised of the field’s recent state and research tendency.
Journal ArticleDOI
Nonlinear topology optimization of parallel-grasping microgripper
TL;DR: A piezo-driven microgripper which can realize parallel grasping in a large displacement range (more than 140 μ m) and the comparison of the convergence results shows that this method can find a better structure of microGripper and save computation time simultaneously.

Benliang Zhu,Benliang Zhu,Xianmin Zhang,Hai Li,Junwen Liang,Rixin Wang,Hao Li,Shinji Nishiwaki +7 more
TL;DR: This paper presents an 89-line code for nonlinear topology optimization written in FreeFEM based on the popular SIMP (solid isotropic material with penalization) method.
Journal ArticleDOI
An Approach for Geometrically Nonlinear Topology Optimization Using Moving Wide-Bézier Components With Constrained Ends
Benliang Zhu,Rixin Wang,Hongchuan Zhang,Hai Li,Junwen Liang,Xianmin Zhang,Hao Li,Shinji Nishiwaki +7 more
TL;DR: This study intends to present a method for geometrically nonlinear explicit topology optimization using moving wide-Bézier components with constrained ends that efficiently avoid the convergence issues associated with nonlinear structural response analysis and can easily achieve minimum length scale control without adding constraints.
Journal ArticleDOI
