implemented on ...
About Dynamic Stability Analysis of the Power Regulators With Exactly Hyperbolic Characteristic
(Universitatea "Dunărea de Jos" din Galați, 2003)
Power regulators are attached devices of hydraulic pumps with variable
capacity. Theses have the means to modify the pump capacity depending of
the pressure from the circuit served by the pump. In this way, it result ...
The Character of the Dynamic Processes in the Proportional Servodriving Systems of the Hydraulic Pumps Capacity
(Universitatea "Dunărea de Jos" din Galați, 2003)
The proportional servodriving systems of hydraulics pump capacity are
used in many more applications in tehnological equipments driving. Thus,
the construction of specialized pumping hydraulics units, like the A10VG
and ...
Influence of Geometrical Parameters on Rigidity of the Worm-Gearing Tooth
(Universitatea "Dunărea de Jos" din Galați, 2002)
By means of an original numerical method, the authors study the influence of the parameters of the worm-gearing tooth (diametral quotient, radius of profile curvature, profile angle of the worm, number of gear teeth) on ...
A Method for Establishing by Controlled Aproximation of the Limitted Forces Developed by Alignmed of the Hydraulic Cylinder
(Universitatea "Dunărea de Jos" din Galați, 2002)
Determination of the limited forces – in case of the mechanisms actioned by the alignmed of the hydraulic cylinders is a very difficult problem to be realized very exactly. This paper presents a numerical method with a ...
