“…TPO/MA menggunakan ketiga algoritma ini untuk melakukan analisis non-linear geometri pada struktur tensegrity dua dan tiga dimensi. Kedua struktur tensegrity yang dianalisis diambil dari penelitian Nuhoglu & Korkmaz (2011) dan Toklu & Uzun (2016) sebagai pembanding dalam mengevaluasi performa algoritma dan akurasi hasil analisis. Permodelan struktur dan proses analisis dilakukan menggunakan program yang dikembangkan secara mandiri dalam software MATLAB 2017b.…”

Total potential energy optimization with metaheuristic methods (TPO/MA) adalah metode analisis struktur yang berdasarkan pada prinsip energi minimum. Metode ini dapat melakukan analisis non-linear pada berbagai struktur tanpa modifikasi yang signifikan dalam prosesnya. Salah satu struktur yang bersifat sangat non-linear adalah struktur tensegrity. TPO/MA dengan tiga algoritma metaheuristik yaitu teaching–learning-based optimization (TLBO), harmony search (HS), dan symbiotic organisms search (SOS) diaplikasikan dalam analisis non-linear geometri pada struktur tensegrity dua dan tiga dimensi. Analisis struktur dilakukan dengan pemberian beban bertahap (incremental) untuk menghasilkan grafik load-displacement yang menunjukkan perilaku non-linear struktur. Hasil penelitian menunjukkan TPO/MA dapat melakukan analisis non-linear pada struktur tensegrity dengan akurasi dan konsistensi yang tinggi. TLBO dan SOS memiliki performa yang lebih baik dibandingkan HS dalam menyelesaikan analisis non-linear pada struktur tensegrity menggunakan TPO/MA.

Compared with conventional mechanisms, tensegrity mechanisms have many attractive characteristics such as light weight, high ratio of strength to weight, and accuracy of modeling. In this paper, the kinematics, singularity, and workspaces of a planar 4-bar tensegrity mechanism have been investigated. Firstly, the analytical solutions to the forward and inverse kinematic problems are found by using an energy based method. Secondly, the definition of a tensegrity mechanism’s Jacobian is introduced. As a consequence, the singularity analysis of the planar 4-bar tensegrity mechanism has been completed. Thirdly, the actuator and output workspaces are mapped. Finally, some attractive characteristics of the mechanism are concluded.

“…Crane et al [23] proposed an analytical method to investigate the responses of cylindrical tensegrities. Recently, Nuhoglu and Korkmaz [24] proposed a point iterative method to analyze the deformation behavior of tensegrities. Tran and Lee [11] adopted a finite element scheme to analyze the responses of tensegrities accounting for both geometric and material nonlinearities.…”

An efficient numerical method is developed to analyze the mechanical responses of tensegrity structures subjected to various actuations that lead to large and highly nonlinear (e.g., hardening or softening) deformations. The proposed method, whose accuracy and efficacy are demonstrated through a number of representative examples, holds promise for applications in design, analysis, and safety evaluations of large-scale tensegrity structures.
