Título del libro: Asme International Mechanical Engineering Congress And Exposition, Proceedings (imece) Título del capítulo: EXPERIMENTAL DETERMINATION OF AXIAL VISCOELASTICITY OF BRAIDED STEEL CABLES THROUGH THE DESIGN OF A SPECIAL PURPOSE MACHINE
Braided steel cables have the potential for improving the mechanisms
providing them several advantages in comparison with rigid elements.
Nevertheless, a limitation in the use of cable mechanism is that due to
the inherent flexibility, the problem of vibration arises. In this
research, we investigate the axial viscoelastic behavior of 1/32 `'
braided steel cables. The essential idea is to determine the parameters
of elasticity (k) and viscosity (b) as a function of the length of the
cable in its axial direction. It was achieved through the design and
construction of a test bench and the design of an experiment. The test
bench is a free vibration particular design machine. One end of the
cable is fixed to the structure, and in the other end, a load is
attached. Then, the load is released, and the free vibration of the
cable in the axial direction is registered. The factor of the experiment
is the length of the cable. There are six levels, and these were
repeated four times. We demonstrated that the braided steel cables have
a viscoelastic behavior like a Kelvin-Voigt. Also, we found a relation
between the effective length of the cables and the parameters of
elasticity and viscosity.
