Definitions
- the method comprises a step of applying an impulse response filter to the arrow signals, said impulse response filter being characterized by a polynomial function whose coefficients are determined from a reverse transfer function of said device. measured.
- the method comprises a step of applying an impulse response filter to the arrow signals, said impulse response filter being characterized by a polynomial function whose coefficients are determined from an inverse transfer function of said measuring device. .
- the three rolling assemblies 311a, 311b furthermore comprise magnetic means 3113 intended to keep the wheel 3111 pressed, and by therefore the platform 31, against the first rail line 6, to avoid derailments of said platform.
- the fourth rolling assembly comprises a wheel 321 intended to rest on the rolling plane 72 of the second rail line 7.
- the slide link 36 is intended to prevent the recesses or derailments of the wheel 321 of the fourth rolling assembly 32 of the second rail run 7 and to distort the measurements recorded by the measuring device. Such recesses or derailments could occur when the railway has a curve or simply when disturbing elements, such as pebbles, are on the rolling plane 72 of the second rail line 7.
- the first means of measurement of the devers are preferably an inclinometer for measuring an angle in the plane Y0Z.
- the displacement sensor is positioned on a so-called horizontal face of the connecting bar of the guide carriage, when the measuring device is in place on the railroad track in order to differentially measure the position of the measuring plate carrying the rolling elements and the connecting bar.
- This signal obtained from an extrapolation is called "signal of arrows equivalent on a long base”.
- the "equivalent 31 m base arrows" correspond to a transition from the short base to the long base by the multiplication method of the amplitude of each component of the short base signal by a ratio for each component.
- the total response of the measuring device corresponds to the sum of the unit responses.
- the transfer function of the measuring device will therefore be easily determined by the study of each elementary response to these unitary inputs.
- the kinematic modeling, by numerical calculation, of a measuring device rolling on a railway makes it possible to determine the modification of the amplitude and the phase of the elementary signals by the filter constituted by said measuring device. Since the transfer function is a mathematical function of the wavelength of the frequency components describing the dressage (or leveling) and the asymmetry of the measurement on the string materializing the relative measurement base, the algorithm works by iteration with a sufficiently narrow pitch.
