Аннотация
Wake-induced oscillations of bundled conductors are caused by
shielding of leeward conductors of a bundle by windward ones. The
conductor motions take the form of traveling vibration waves moving in the
bundle. Analysis is carried out in terms of normal wave propagation modes,
each mode being a certain combination of wave motions in the conductors of
the bundle that propagates independently of the other modes. The transfer
matrix method is used to determine whether a set of propagation modes
exists. for given wind conditions. that can satisfy boundary conditions at
span supports and thus indicate the possibility of stable oscillation.
