Natural frequencies describe the pre-stress in tensegrity structures
We studied resonance frequencies in pre-stressed non-linear tensegrity structures. We used for the simulations beam elements with axial-transversal coupling. Resonance was evaluated at pre-stressed equilibrium states. We distinguished between two settings, design and production. We concluded that vibration frequencies are important descriptors of the pre-stress state.
