Abstract:

The study and detection of cavitation in hydraulic turbo-machinery has gained recently particular attention from both manufacturers and end users, due to the damage caused on machines’ surfaces that may result in costly sudden shutdowns. The traditional cavitation detection approaches exploit the noise and vibration signals that sense the vapor bubble implosion pressure waves, while advanced demodulation techniques are used in order to locate the resonances excited from these waves. This work aims to investigate an alternative methodology, where detection is achieved by processing the speed si

Abstract:

At present, the axis orbit (whirling) and the instantaneous angular speed (spinning) are important symptoms in the condition monitoring of rotor systems. However, because of the lack of research of the transient characteristics of axis orbit within a whirl cycle, the axis orbit cannot reflect the instantaneous characteristics of the rotation during one whirling cycle like the instantaneous angular speed. Therefore, in this paper, a new concept of instantaneous whirling speed of axis orbit within a whirling cycle is proposed and defined. In addition, the transient characteristics of instantaneo

Abstract This paper introduces a new approach in instantaneous angular speed monitoring using a two-phase n poles AC generator as sensor. A two-phase n poles (n=50) stepper motor plays the role of sensor. Its rotor is firmly connected to the rotary part whose instantaneous angular speed should be measured. The sensor produces two identical sinusoidal EMF (electromotive force) signals (theoretically shifted with π/2 radians) with the same periods T. This paper proposes to use the mathematical product of the numerical descriptions of these EMF signals in order to define a new EMF signal with a p

The axial piston pump is a core component for power output conversion in the hydraulic system. Monitoring pump status and diagnosing faults in an optimal way are of profound significance for ensuring system reliability.

Abstract:

Defect diagnosis of rolling element bearings operating under time-varying rotational speeds entails order tracking and analysis techniques that convert a vibration signal from the time domain to the angle domain to eliminate the effect of speed variations. When a signal is resampled at a constant angular increment, the amount of data padded into each data segment will vary, depending on the rate of change in the rotational speeds. This leads to changes in the distance between the adjacent impulse peaks, and consequently, the result of order analysis. This paper presents a quantitative analysis

Abstract:

<strong><em>Article History</em></strong>   Received: January 04, 2021     <em>The effectiveness of throwing a hammer is one of the of games that require high-level technical performance and requires that the archers possess a correlation in Physical abilities such as types of strength rotational speed and compatibility as well as mastering the technical aspects according to the mechanical conditions that characterize this effectiveness, Through the experience of field researchers in the field of athletics, especially in throwing events, he noted that there is a low level of dig
