This paper aims at investigating the effect of thermal stress on free linear vibrations of cables. An analytical model extending Irvine’s theory to thermoelasticity is proposed. In addition to the sag-extensibility parameter, this model yields a second dimensionless independent parameter related to the temperature change. Some general two-dimensional contour plots are presented giving the relat...

The vBow senses the violinist's bow stroke through the encoder of a servo driven by a cable, which is wrapped around a capstan attached to the shaft of the motor, and secured to either end of the virtual bow. The servo engages the bow, simulating friction and vibration of the string on the bow, according to the velocity of the performer's stroke. The result is a musical controller capable of si...

In this correspondence, we show that the spectrum-determined growth condition holds for the closed-loop system of a vibration cable with a tip mass and linear boundary feedback control. The optimal decay rate of the energy for a case left unsolved in the [1] is determined, and the asymptotic expansion of the associated semigroup is obtained. As a consequence of the approach, we show, in a diffe...

Abstract Non-destructive evaluation has been developed to identify cable tension for any end-rotational stiffness condition. One of the existing methods uses multiple vibration measurements. This paper aims study effect shifting closest sensor support in measurements through numerical simulation. A fixed at both ends vibrates under artificial random excitation is simulated. Three cases five syn...

In this paper robust PID control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. In dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. To develop the idea of control for cable robots with elastic cables, a robust PID control for cable driven robots with ideal rigid cables is firstly de...

This paper proposes a vibration model for modal analysis and control of vertical cable-dual tuned mass damper (C-DTMD) coupled system. The proposed introduces several non-dimensional parameters to describe the in-plane Moreover, phenomenon split is comprehensively studied present complex modes. Parameter conducted show influence length ratio, damping frequency ratio on reduction. In addition, t...

Aiming at the problem of cable breakage an asymmetric single-tower cable-stayed bridge by taking a that has been in operation for more than 20 years as engineering example, spatial finite element model reflected actual stress state structure was established and method solving time point proposed. The results show strength main girder, pylon could meet requirements vibration caused successive br...
