Stress-constrained topology optimization for compliant mechanism design

Abstract: O. (2015). Stress-constrained topology optimization for compliant mechanism design. Structural and Multidisciplinary Optimization, 52(5), 929-943. https://doi.org/10.1007/s00158-015-1279-z Abstract This article presents an application of stressconstrained topology optimization to compliant mechanism design. An output displacement maximization formulation is used, together with the SIMP approach and a projection method to ensure convergence to nearly discrete designs. The maximum stress is approximated using a … Show more

“…Wang et al [128] used the level set method to track the motion of the actuator and the independent point-wise density interpolation (iPDI) method to optimize the structure, so as to realize the optimization of both actuating position and structure. De Leon et al [129] added the stress constraint in the optimization to avoid the one-node-connected hinge problem. In addition, Yoo et al [130] used modified ant colony optimization (MACO) to improve the computational efficiency of SIMP.…”

“…There is no need to pre-determine the number of links or the location of the flexural joints in the device [14]. In the past decades, many different techniques, such as the homogenization method [15], solid isotropic material with penalization (SIMP) method [16][17][18], level set method [19,20], evolutionary structural optimization (ESO) method [21,22] and others [23][24][25], have been developed. To a great extent, structure synthesis methods of spatial compliant mechanisms are faced with many complicated factors, especially the following two main issues.…”

“…O filtro de densidade tradicional, de Bruns e Tortorelli (2001), foi introduzido na literatura como uma alternativa matematicamente consistente ao filtro de gradiente proposto por Sigmund (1994). Apesar de ter sido originalmente utilizado na solução de problemas de flexibilidade e de mecanismos flexíveis, o filtro de densidade tem sido utilizado na solução de diversos problemas, na literatura, inclusive na solução de problemas baseados em tensão (BRUGGI; DUYSINX, 2012;TORSTENFELT;KLARBRING, 2013;KIYONO et al, 2016;LE et al, 2010;LEON et al, 2015;SVÄRD, 2015;QIAN, 2018). Além disso, o filtro de densidade é utilizado como base para métodos mais sofisticados, como os métodos de projeção descritos na subseção 2.2.2.…”

“…O problema contínuo de otimização topológica com restrição de tensão foi inicialmente abordado em Duysinx e Bendsøe (1998), onde a abordagem baseada em densidade é empregada para a obtenção de estruturas de mínima massa que respeitam um critério de falha em tensão estabelecido a priori. Desde então, o problema baseado em tensão ganhou bastante popularidade na literatura (AMSTUTZ; NOVOTNY, 2010; AMSTUTZ; NOVOTNY; NETO, 2012;BRUGGI, 2008;BRUGGI;DUYSINX, 2012;SIG-MUND, 1998;FANCELLO, 2014;FANCELLO, 2019;FANCELLO, 2006;FANCELLO;PEREIRA, 2003;TORSTENFELT;KLARBRING, 2013;KIYONO;REDDY, 2016;KIYONO et al, 2016;LE et al, 2010;LIAN et al, 2017;LEON et al, 2015;LONG;NOVOTNY, 2016;LUO;KANG, 2013;PARÍS et al, 2009;FANCELLO;BARCELLOS, 2004;PICELLI et al, 2018;NOVOTNY, 2017;SVÄRD, 2015;TROYA;TORTORELLI, 2018;QIAN, 2018), devido principalmente a necessidade de se considerar requisitos de projeto mais realísticos na otimização estrutural.…”
