Tensegrity is a class of pre-stressed structures in which tension provides integrity. Tensegrity-membrane systems arerncomprised of membranes, bars, and cables or tendons. They belong to the class of flexible multibody structures andrncan be treated as an extension of tensegrity systems and their members perform functions such asrnsensing, actuating, and feedback controlling simultaneously. The low weight and structural integrity make tensegrities an important component in airospace applications. The present work analyzes the numerical and experimental aspects of prediction of vibration of a pre-stressed triangular tensegrity membrane.
