description: Non-stationary localized oscillations of an infinite string on the Winkler fondation
with a point inhomogeneity (point moving oscillator) are considered. In
such a system with constant parameters (fixed oscillator) under certain conditions,
the mode of oscillations exists and is unique. Therefore, the application of nonstationary
external excitation to this system can lead to the appearance of string
oscillations localized near the inhomogeneity. We present an analytical description
of nonstationary localized oscillations in a system with time-varying properties using
an asymptotic procedure based on an asymptotic method, namely, method of
the stationary phase. The obtained analytical results are confirmed by independent
numerical calculations. The applicability of analytical formulas has been
demonstrated for various types of external excitation and absolute speed values.
In particular, it is shown that in this case the trapped mode disappears before the
speed approaches the speed of sound.
