ABSTRACT:
A process and a system for measuring and recording undulatory deformations of a rail surface. A feeling device is moved along the rail surface and an accelerometer is connected to the feeling device to generate a voltage signal representative of the acceleration encountered by the feeling device in contact with the deformations. The signal is amplified and filtered in function of the speed of the vehicle carrying the system, and thereafter twice integrated, then rectified and amplitude-modulated in function of the vehicle speed. A filter eliminates spurious signals from the modulated signal and a recording of the lastly filtered signal is effected. In addition, there is also provided a circuit for measuring and recording sound signals generated by the rolling vehicle.
