Summary. Stability of vibrations of a single-mass oscillator moving uniformly along the Euler-Bernoulli beam is studied. The energy analysis of the oscillator vibration is performed. It is shown that the vibration can be unstable only if the oscillator generates in the beam anomalous Doppler waves. The stability domain in space of the system parameters is found.
