Abstract
This paper investigates the stability and stiffness characteristics of two-dimensional tensegrity structures based on two equilateral triangles connected by tensioned members, resulting in three multistable structural variants. The stability analysis is conducted by examining the system’s potential energy. Using a form-finding algorithm, the study reveals how the stiffness of tensioned members impacts global compliance distribution and the transition between equilibrium positions. By adjusting the stiffness of individual members and varying force application points, significant modifications in the overall stiffness of the structure can occur. The study shows that increasing the force amplitude can lead to equilibrium position changes, particularly in asymmetrical structures. These findings provide valuable insights for designing adaptable, stiffness-tunable structures. The results emphasize the critical role of force direction, stiffness distribution, and transitions between stable equilibrium states in the development of advanced mechanical systems.
