“…However, these techniques are limited in case of planning of diagnostic experiments, which are often conditioned by the possibilities of their realization. Therefore, in diagnostic tests, aimed at defining the relationship state  signal, with the assumption of a cause-and-effect action of the diagnosed object, there are three types of diagnostic experiments distinguished [6,7,11,12]:…”

Abstract. The article presents a method of selecting diagnostic parameters which map the process of damaging the object. This method consists in calculating, during the observation, the correlation coefficient between the intensity of damage and the individual diagnostic parameters; and discarding of those parameters whose correlation coefficient values are outside of the narrowest confidence interval of the correlation coefficient. The characteristic feature of this method is that the parameters are reduced during the diagnostic experiment. The essence of the proposed method is illustrated by the vibration diagnosis of an internal combustion engine.

“…A separate issue raised by many researchers in [24,31,52] is the vibration and noise generated by brakes during braking. In papers [17,18,50,51], vibroacoustic signals in the time domain, amplitudes and frequencies have been analyzed, allowing for the evaluation of rotary machines, brakes and identification of faults.…”

Similarly to road vehicles, a disc brake remains the main friction brake in rail vehicles. Due to the increasing train speeds, a disc brake has already replaced the traditional clasp brake that is however, still used in cargo trains. In the process of long-term operation of the brake pad-brake disc friction pair, the parameters of the braking process such as the curve of the coefficient of friction are changed, which extends the braking distance. The paper presents the results of several years of investigations on the railway disc brake in different wear conditions in the aspect of the requirements set by the UIC (International Union of Railways) related to the brake pads approval for use.
