Vibration Of A Long, Tip Pulled Deflected Beam

Abstract

A study was conducted to address the problem of building a simple dynamic model of a long beam deformed by a tip pulling cable. The exact static deformation shape of a long beam was obtained through the solution of the nonlinear beam governing differential equations. The exact deformed configuration for beams with a uniform cross section and transversal end load was found through the recursive solution of elliptic integrals. The deformed configuration of beams with an inclined pulling force was found via numerical approximations, using adequate methods such as the Runge-Kutta method, the finite element method, and the quasi-linearization finite difference method. A strategy to calculate the static deformation of a long beam pulled by a tip cable was also proposed in the study.52715591563Puig, L., Barton, A., Rando, N., A review on large deployable structures for astrophysics missions (2010) Acta Astronautica, 67 (1-2), pp. 12-26. , July-Aug. doi:10.1016/j.actaastro.2010.02.021Tibert, G., (2002) Deployable Tensegrity Structures for Space Applications, pp. 9-30. , Royal Inst, of Technology, StockholmPellegrino, S., (2001) Deployable Structures, pp. 1-35. , Springer MilanFrisch-Fay, R., (1962) Flexible Bars, pp. 33-64. , Butterworths LondonTimoshenko, S., Gere, J., (1961) Theory of Elastic Stability, pp. 66-70. , 2nd ed.
