A formulation is proposed to investigate the effect of horizontal constraints in regard to the lateral displacements of a long elevator rope on the undamped flexural vibration modes. The formulation is based on a model of the rope as a serial assembly of virtual rotary springs and rigid links. The horizontal constraints are modeled by virtual rectilinear springs and expressed as equality constraint conditions imposed on the lateral displacements. The undamped vibration eigenvalue problem is derived from the Lagrange's equation of motion in terms of the potential energy and kinetic energy of the springs and links. The numerical examples are concerned with a rope system consisting of the main rope, cab and compensation rope that stand for an elevator system while the relative lateral displacements of the cab and bottom end of the rope to the top end are constrained.
