Abstract

A vibration damped elevator system is provided that includes a damper or dampers attached to the elevator cable. The damping coefficients of the damper or dampers are chosen to provide optimum dissipation of the vibratory energy in the elevator cable. A method of determin8ing the optimum placement of the damper or dampers and their respective damping coefficients is also provided.
