Advanced Numerical Modeling of Nonlinear Elastic Cable With Recovery Characteristics

Abstract

Cable driven parallel robots (CDPRs) have many advantages such as low inertia and large workspace. These advantages lead to the industrial applications. CDPRs mainly use Dyneema polymer cable for more high sensitivity because it has advantage of the lower weight than steel wire. However, the polymer cable is continuously deformed when actuating the CDPR because of the elasto-plastic cable characteristics such as recovery. In this paper, numerical cable recovery was proposed using the modified burger model. Finally, the models were simulated and compared with the experimental profiles. As the result, the simulations are good agreement with the experimental profiles.
