Forced harmonic motion and random vibrations of the string moving to the longitudinal direction
The homogeneous string moving in lengthwise direction is described. Forced motion at kinematic gusts is explored. The influence of velocities and quarters phases on amplitude of oscillation and coupled modes are analyzed at harmonic gust. Fourier density and dispersion are defined for stationary random vector gusts. Depending on the parameters of departures from the correlation gusts array are identified.
