The influences of undissolved air into the hydraulic agent on dynamics of hydraulic system with rotational drive unit
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2010, Vol 7, Issue 2
Abstract
It is well known from the exploitation activities of hydraulic driving systems that the undissolved air into the hydraulic agent of technological equipments actuating system generates the negative effects regarding the system behavior. These negative effects are due to the cavitations phenomenon, the intensive acoustical phenomenon, as a fact of dynamic characteristics changing of actuating system (natural pulsation, damping parameter, disturbing factors, the frequency of pressure oscillations, etc). This paper presents the qualitative and quantitative analysis of undissolved air percentage influence on hydraulic system dynamic behavior. There are deduced and presented the mathematical model of these influences. This analysis provides a strong argument to avoid of dynamic phenomenon due to the air absorption in hydraulic systems. Hereby this study is very useful both for designers, and for researchers on the technological equipments with hydraulic actuating area.
