Finite Element Model for Catenary in Initial Equilibrium State

  • Received Date: 21 Dec 2008
  • Publish Date: 12 Nov 2009
  • Finite element models were established using link and beam elements,respectively,to accurately and quickly calculate the dropper lengths,static stiffness,natural frequencies and mode shapes of catenaries in the initial equilibrium state.The results show that the two element types exert no obvious effect on the static and dynamic simulation results;the calculation efficiency can be improved using the link elements due to their fewer freedom degrees;the equilibrium positions and the axial stiffness of the elements should be determined in advance when the static stiffness and mode shapes are calculated.
