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 ... -
Influence of the Behavior of Nonlinear viscoelastic Systems Bearing on the Dynamic of Bridge Structures
(Unioversitatea "Dunărea de Jos' dibn Galati, 2011)Modern structures of bridges and viaducts require dynamic isolation systems, designed to eliminate or mitigate the destructive effects of intense traffic and seismic activity on these constructions. This paper studies ... -
Influence of the Road Dislevels Upon the Traction System of the Self-Propelled Machines
(Universitatea "Dunărea de Jos" din Galați, 2007)The kinematic response is caused by run away about the equipment of the movement modeled in the mechanic system with degree of freedom. The kinematic excitation considered produces harmonic formally to the organ axle of ... -
Influence on Energy Efficiency Oof Mechanisms Operated With Hydraulic Cylinders
(Universitatea "Dunărea de Jos" din Galați, 2013-05-01)During the operation of mechanisms operated by hydraulic cylinders significant energy losses occur. They is due to the loss of flow, pressure and friction losses that occur in the system. This paper highlights the connection ... -
