Abstarct: Tensegrities are a kind of spatial structural system (2D or 3D) composed of cable (in tension) and strut (incompression).which cables are continuous, but the compressed elements are interrupted or suspended. Stability of this system is provided by the selfstress state between tensioned and compressed elements. In this study dynamics equations of tensegrity structure was investigated to reduce vibration using control of strings (cables) length. To achieve this, a 3D model of tensegrity structure that compossed of six bar in two stage (6 bar SVD) are studied. And in following after modeling and deployment the tensegrity structure consider nonlinear dynamic equations, the tension forces of strings are calculated and geometry of this tensegrity structure to be considered as function of strings length. Then driver motor and pulley size are calculated to. Using obtained vibration magnitude of tensegrity structure depend on strings position and adjustable strings length via position of controlled driven motor (DC) shaft will be minimized.
