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 ...

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 ...

The workpaper proposes a computer assisted modality of projection in order to obtain casting semiforms, starting from the 3D totally standardized model of the casting piece. The advantage of such a method is that the ...

The work has as purpose to present the general principles of working with the technological processors in designing the casting technologies and to put into evidence the advantages of this designing method. As examples, the ...

This paper proposes a method for evaluating the stress of the unit body of the hydraulic cylinder and the rod which was at work and the Hydraulic Brake at the end of the race. The paper analyzes the situation in which ...

It was in the frame of the „Restoration of the aquatic and terrestrial ecosystems complex, from Fundu Mare Island, part of the Small Wetland of Brăila - RAMSAR site 1074” project to look for solutions to improve the hydro ...

Numerical simulation of the operation of hydraulic systems acting on hydraulic cylinderst is based on differential equations that describe the equilibrium of forces and the continuity of the flow rate. To simplify ...

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 ...

This paper presents some aspects related to the way the cushioning capacity of hydraulic cylinder is affected by the temperature variations of the hydraulic fluid. We have analysed the case of the hydraulic cylinders with ...

the description of the kinematics of mechanisms driven by hydraulic cylinders, hydraulic agent is usually considered incompressible. This computing hypothesis introduces errors which, in certain situations, can not be ...
