  • the auxiliary power of a side-by-side cylinder is shown as a function of a supply path and an indicator is defined by the energy consumption. Accordingly, the energy supplied to the ballast via the auxiliary cylinder is considered by this reference number. In this way, however, the energy lost in the system is not taken into account.
  • the object of the present invention is now to provide a method of the type mentioned above, with which an improved recognizability of achievable by the compacting tools ballast compaction is possible.
  • Another object of the invention is also to provide a vibratory compacting tool having tamping aggregate which enables uniform crushing of the ballast.
  • the invention features - with the advantageous exclusion of constructive energy losses - a registration of the energy transmitted directly into the ballast and thus a meaningful index for achieving an optimal ballast compaction possible. borrowed.
  • the maximum possible dynamic additional force can be found just below a threshold value. Consequently, the ballast is not destroyed by excessive compression and reliably precludes a very disadvantageous lateral drainage in the threshold longitudinal direction.
  • the additional time and supply force necessary for the desired compaction can be metered in a targeted manner.
  • the method features according to the invention can generally be used to improve equipment suitable for ballast compaction so that in each case an accurate statement (or index number) with regard to the achievable degree of compaction is possible.
  • an optimal compression state can be achieved even with different track-bound compaction, stuffing and track stabilization machines.

  • FIG. 2 shows a schematic representation of a compacting tool
  • FIG. 3 shows acceleration signals.
  • a ballast bed consists essentially of two each about a pivot axis 4 pivoting Stopfhebeln 5. These are at a lower end 6 each with a to penetrate provided in the ballast 3 compaction tool or tamping 7 and connected at an upper end 8 with a hydraulic Beistellantrieb 9.
  • Each Beistellantrieb 9 is mounted on a rotatable by an eccentric 10 eccentric shaft 11. This vibration vibrations are generated, which via the Beistellantrieb 9, the Stopfhe- at 5 and the compacting tool 7 are transferred to the crushed stone 3 to be compacted.
  • a connected to a control unit 12 acceleration sensor 3 is arranged. This could alternatively be attached directly to the compacting tool 7.
  • the acceleration sensor could also be arranged on a compacting tool designed as a track stabilizer and displacing the track into vibrations.
  • the acceleration of the vibrating compacting tool or stuffing plug 7 serves as an input to the system for determining the compaction quality. Normally, this does not perform any harmonic motion but works in a non-linear mode. It will transfer the forces on the ballast 3 only in one direction, it may lead to a lifting of the ballast grains of the Pimple surfaces come. This creates jumps in the force curve that distort the harmonic acceleration signal.
  • a maximum possible degree of compaction can be calculated with the acceleration sensor 13 within a time interval. It is thus possible to obtain the information that the ballast 3 located between the compacting tools 7 has not yet been compressed to a maximum degree corresponding to a specific value of the acceleration signal. If necessary, another stuffing process can be initiated. In an advantageous manner, it can also be documented that the degree of compaction has been produced homogeneously, in particular during a longer stuffing period.
  • Gravel 3 as resonator a vibratory system The resonance of the dynamic system is changed by the compression as the system's equivalent stiffness changes. With the aid of the frequency response of the dynamic system, the resonance frequency can be evaluated. It would also be advantageous to track the frequency of this resonant frequency.
  • a power density spectrum or spectral power density indicates the power of a signal in relation to the frequency in an infinitesimal (limit-to-zero) frequency band.
  • the acceleration signals are deformed as soon as a load occurs. This is visualized by the calculation of the power density spectrum and summed up in the range below 50Hz for the power of the fundamental and above 50 Hz for the power of the harmonics.
  • the measure of ballast compaction is the harmonic content (OSG).
  • the OSG of a harmonic sinusoidal fundamental signal of the acceleration is influenced by the nonlinear behavior of the feedback (reflection) of the ballast.
  • the harmonic content is referred to as the dimensionless quantity and indicates the extent to which the power of the harmonics superimposes the power of the sinusoidal fundamental.
  • FIG. 3a shows the acceleration signal with unloaded compacting tool 7, FIGS. 3b and 3c with medium or high compression (the time t is indicated on the x-axis and the acceleration on the y-axis).
  • a comparison shows a significant change in the shape of the sine function.
  • the spectral components of the acceleration signal increase in the harmonic range.
  • Fig. 3d The course of the spectral power density of the three acceleration signals presented is shown in Fig. 3d (x-axis corresponds to the frequency Hz, the y-axis the power density spectrum W / Hz).
  • the main frequency components are at 35 Hz.
  • the curve marked with a dashed line several higher frequency components occur and even more higher frequency components occur in the curve shown by dot-dash lines. These higher frequency components are responsible for the deformation of the originally sinusoidal acceleration signal.
  • time-limited portions of the acceleration signal are selected and fed to a calculation routine for the power density spectrum. This calculates the power density spectrum in the frequency band from 5 to 300 Hz.
  • the power is determined by integrating the spectral power density over the desired frequency range. It the fundamental vibration power (LGS) and the harmonic content (OSG) are determined as follows:
  • a cutoff frequency f1 between fundamental oscillation (LGS) and harmonic depends on the resonance frequency of the mechanical construction of the tamping unit 1 and is determined by the course of the power density spectrum (PSD).
  • the evaluation of an acceleration signal is described below.
  • the individual measured variables for the auxiliary travel of the compacting tools 7 and their additional time are divided into several temporal sections.
  • the characteristic values for LGS and OSG are determined for the front and rear compacting tool 7 with respect to a working direction of a tamping machine.
  • the compacting operation or the auxiliary movement of the compacting tools 7 can advantageously be terminated immediately as soon as the characteristic value OSG has reached a preset size.
  • To determine an apparent power is a drive power of the eccentric 10. This is detected by the pressure curve metrologically and subtracted the reactive power of the Beistellantriebe 9, since the power is lost at this point.
  • ballast force is determined by means of the measured acceleration of the compaction tool 7. This is an indication of gravel compaction.
  • the working process ballast compaction can be divided into the following sections: immersion, addition and start-up of the compacting tool 7. The actual compaction process takes place during the addition.

  • auxiliary drives 9 which also serves as a force-limiting overload protection in the system. If the force limit is active, more reactive power is consumed.
  • the reactive power can be done by measuring the power in the auxiliary drive 9. For this purpose, the resulting cylinder force and the speed that covers the piston rod relative to the Beistellantrieb 9, needed.
  • the resulting cylinder force can be done by two pressure sensors in the auxiliary drive 9.
  • a transducer in the hydraulic cylinder can be used for the determi- Speed can be used by differentiating the path once.

  • the speed traveled and the path of the compacting tool 7 is necessary.
  • the acceleration signal is integrated once and twice for the route.
  • the energy flowing into the ballast 3 during compression by the tamping plow 7 can be described as follows:

Abstract

Le ballast (3) situé au-dessous des traverses d'une voie est soumis à un compactage par l'introduction d'outils de compactage (7) animés de vibrations et leur mise à disposition. Les vibrations transmisses au ballast (3) pendant l'opération de compactage sont enregistrées sous forme d'indication pour le compactage du ballast. Cela permet d'obtenir une voie de compactage homogène même pour différentes propriétés de ballast.
