“…Paper [9] examined the vibration loads caused by the technological bodies of the units while other types of loads remained unattended. Study [10] analyzed the procedures for determining vibration loads on moving units while other methods were not considered. Paper [11] addresses to a mathematical model of the value of the parameters in the drag system, but the methodology for designing the drag system is not described.…”

The entropy theory finds wider and wider applications in the description of real time series recorded in complex systems. The relation of the multifractal spectrum with the Renyi dimension allows to assess the generalised entropy of time series based on the multifractal formalism. The aim of the hereby paper is to present the form and properties of entropy, which can be used in defining measures in the comparative analysis of mechanical vibrations time series being the main information source on the complex systems states. The obtained results were verified for signals recorded in various maintenance states of the drive system of the spark ignition vehicle, being the effect of active experiment with implemented typical mechanical defects.

“…e failure of a part not only affects the machine operation but may also cause considerable economic losses or even catastrophic consequences. Common engine failures include wear, distortion, cavitation, and corrosion, and different faults can be detected in various approaches, such as tail gas, power and speed, oil, and vibration and noise analytical methods [1][2][3][4][5].…”

This paper presents a developed dislocation superimposed method (DSM) for automatically extracting the component of impulsive signals from abnormal noise signals of an engine at a single speed range on the basis of the initial DSM. This method consists of three steps: using a correlation analysis to select an appropriate starting superposition point, superimposing abnormal sound signals to improve the signal-to-noise ratio, and intercepting superimposed signals to separate the fault component. Experimental results show that the developed DSM can effectively extract the fault characteristics of cylinder knocking and connecting rod bearing knocking. The developed approach can be applied to separate the fault characteristics of other types of rotating machines.
