“…In contrast, because of the decrease of stiffness under high excitation frequency, optimization cannot motivate the material to distribute among the loading path, therefore it failed to generate a clear configuration (Figure 4b). Similar distorted configurations can be found in references [14,15].…”

“…Jog [14] presented that the topology optimization for minimizing displacement amplitude at a user-defined point in the structure may result in distorted configurations with large amount of intermediate density elements. Olhoff and Du [15] minimized the dynamic compliance of structure subject to harmonic loads, optimization results show that when the natural resonance frequency of the initial structure is less than the given excitation frequency, the natural resonance frequency will decrease and the static compliance of the structure will increase very quickly.…”

“…Esse tipo de problemaé de suma importância, uma vez que, forças harmônicas, representam uma das principais fontes de vibração ou ruído em estruturas [4,5]. Especificamente, no caso de braços robóticos, as cargas e o torque dos motores das juntas induzem vibrações na estrutura e essas vibrações acabam prejudicando a precisão das tarefas e podem causar danos ao robô.…”

“…Na Tabela 3 consta a comparação entre as três simulações realizadas, com referência aos resultados obtidos da flexibilidade e a alteração da primeira frequência natural. A partir dos resultados obtidos, observa-se que o processo de otimização topológica dirige as frequências naturais da estrutura para valores que estão afastados da frequência de excitação [4] isso evita a ressonância e reduz o nível de vibração da estrutura [8,9].…”
