- W2953675712 abstract "The purpose of the work is to determine the reduced mass of soil, which participates in fluctuations in measurements of dynamic stresses in the earth's canvas. Methodology . In the study, the dynamic stabilizer of the DSP-S4 track on the main track was used. Two work frequencies were given, which are equal to the dynamic fluctuations of the rolling stock of the train. During the study, measurements of acceleration of the track were made using an accelerometer, which was placed on the sole of the rails. Findings. Subsequently, graphs of acceleration of the tracks were constructed, depending on the given frequency and the distance to the dynamic load. For trunk tracks, it is necessary to determine the effect of the forces of inertia in the vertical plane. To establish this value, we need to find the given mass of the track, which is why we conducted an experiment in the field, using a dynamic track stabilizer. Two frequency frequencies of 10 and 27 Hz were given, during which measurements of speed accelerations were made using an accelerometer which was placed on the neck of the rail. Subsequently, graphs of acceleration of the tracks were constructed, depending on the given frequency and the distance to the dynamic load. The method of determining the inertial and dissipative characteristics of the discrete model of the path for forced oscillations was also determined. At the same time, the system was introduced into a resonance, which increases the reliability of the obtained values of the reduced mass and the dissipation coefficient. In the majority of the currently known studies an experimental method is used in which the given mass is determined by measurements of vertical accelerations in some fixed cross-sectional sections of the rail during the transition through these sections of the wheels of the rolling stock, namely, in a fixed coordinate system. Originality . In determining the inertial and dissipative characteristics of the track, the dynamic stabilizer of the DSP-S4 path was used as the causative agent of forced oscillations, during the passage of which the motion of the passenger train was simulated. Practical value lies in the fact that a technique was developed for determining the inertial and dissipative characteristics of the path to forced oscillations." @default.
