Abstract
Beam systems are used in many areas today. They are preferred because of their light weight, high efficiency, high operating speed and low cost, but their excessive vibration causes problems. In order to prevent these vibrations, the rigidity of the system must be high. At this point, the use of cables is of great importance. Cable tensions affect the rigidity of the system. Cabled structures are preferred because lightweight stiffening, easy deployability, and shape control capability. In addition, they are also used in large-sized structures, as they can transmit their effects over long distances. In this study, a linear velocity applied to a flexible beam is given, trapezoidal velocity inputs are given and various acceleration conditions are considered. In the model, natural frequencies are investigated for cableless and cabled situations with different pre-tension values applied. The changes in the endpoint vibrations were investigated by using the transient analysis method via ANSYS workbench. Thus, the effectiveness of using cable pre-tension in beam systems has been demonstrated.
