The inclusion of conductor bending stiffness in the prediction of overhead system normal modes and pantograph response (IM-DA-259)

The following work is an extension of that done by J.A. Elkins (Ref. 1), in which a method for calculating the natural frequencies and normal modes of oscillation of overhead systems was developed. Elkins predictions were not satisfactorily supported by experimental results above 8 Hz, the theoretical and measured values...
