Abstract
A method for compacting a ballast bed, on which railroad ties and track rails secured thereto are supported, uses a work assembly which is arranged on a track construction machine that can be moved on the track. During a compaction process, a signal is detected and a characteristic variable is derived therefrom by an analysis device in order to evaluate the quality of the ballast bed. The work assembly contains an electric drive, by which the compaction process is at least partly carried out. At least one operating variable of the electric drive is supplied to the analysis device, and a ballast bed characteristic variable is derived from the operating variable by the analysis device.
Claims13
A method for consolidating a ballast bed, on which railroad ties and rails, fastened thereto of a track are supported, by means of a working unit disposed on a track maintenance machine mobile on the track, which comprises the steps of:
- detecting a signal during a consolidation procedure executed at least partially by the working unit having an electric drive;
- and
- deriving a ballast bed parameter for evaluation of a quality of the ballast bed from the signal by means of an evaluation device, at least one operating value of the electric drive being supplied to the evaluation device, using the at least one operating value for computing a model value by means of a digital model of a component or several components of the working unit stored in the evaluation device, wherein by means of an electric motor model stored in the evaluation device, a mechanical model value is derived from the at least one operating value being an electric operating value, and that the ballast bed parameter is derived from the at least one operating value by means of the evaluation device.
A device, comprising:
- a machine frame having on-track undercarriages and being mobile via said on-track undercarriages being on a track having railroad ties supported on a ballast bed and rails fastened thereon;
- a working unit mounted on said machine frame for consolidating the ballast bed, said working unit having an electric drive by means of which a consolidation procedure can be executed at least partially;
- and
- an evaluation device for determining a ballast bed parameter for assessment of a quality of the ballast bed, said evaluation device coupled to said electric drive, and said evaluation device being configured for deriving the ballast bed parameter from an operating value of said electric drive supplied to the evaluation device, said evaluation device using the operating value for computing a model value by means of a digital model of a component or several components of said working unit stored in said evaluation device, wherein by means of an electric motor model stored in said evaluation device, a mechanical model value is derived from the at least one operating value being an electric operating value.
