Energy–saving in hydraulic drives in experimental approach and biomimetric similarity

Abstract

The current article presents the research results of the proposed energy-saving way in hydraulic drives based on a biomimetic approach. Experimental measuring for investigation energy consumption by different types of high-pressure hoses and its influence on the inside fluid flow are presented. The methodology presented in this paper for experimental measurement is based on fluid pressure measuring and high-pressure hose vibration measuring analysis. In the research, by experimental measuring, different braided high-pressure hoses, used in modern hydraulic drives, were compared. The research was performed to describe a high-pressure hose behavior dependency on the fluid flow inside and its influence on the energy parameters of the system. The proposed concept for energy-saving in a hydraulic drive is based on biomimetic approaches. In the research it is disclosed that, by using different types of high-pressure hoses, a reduce of power losses and an increasing hydraulic drive efficiency can be achieved, by replacing one type of a high-pressure hose with another type, during machinery hydraulic drive maintenance or on design stage.
