Optimization of hydraulic cylinder housing

International Journal of Fatigue, 1990
Abstract This paper concerns the optimization of the fatigue-critical part of a hydraulic cylinder. The investigation includes optimization, fatigue testing, residual stress measurements, life predictions and, finally, reliability computations. The optimization reduced the critical parameter, the stress intensity factor in the end weld root, by 40 ...

The four-chamber hydraulic cylinder

2016 IEEE International Conference on Aircraft Utility Systems (AUS), 2016
In the control of traditional hydraulic systems, there will be large pressure fluctuations for the ordinary hydraulic cylinders in the condition of varying load. For this case, we design a four-chamber hydraulic cylinder. By using the hollow rod as another cylinder body, we make two-chamber ordinary hydraulic cylinder into four-chambers. In the control

Eigenfrequency Identification of the Hydraulic Cylinder

2021
The paper is focused on the identification of the eigenfrequency of the linear hydraulic servo drive, which consists of the flow control valve and hydraulic cylinder. The behaviour of the closed loop controlled hydraulic drive is given by the dynamic properties of the control valve and hydraulic cylinder.

Optimization of Hydraulic Cylinder

1985
The optimization of hydraulic cylinder is studied. Based on theory of elasticity a mathematical model is established for optimizing main parameters. Meanwhile the boundary in stress concentration region, formed by 3rd order spline function in the course of optimization, is optimized by finite element analysis with mesh generation technique.

Hydraulic Cylinders - State of the Art

SAE Technical Paper Series, 1963
<div class="htmlview paragraph">The extensive use of hydraulic cylinders in operations involving high loads and increasing pressures has brought to light several problems that should be considered and corrected. Some of these include contamination, improper cylinder packing, cylinder squeal, and others.

Steel development for hydraulic cylinders

Materialwissenschaft und Werkstofftechnik, 2008
AbstractHydraulikzylinder steuern Bewegungsabläufe in einer Vielzahl von Geräten und Maschinen, die unter anderem auch im Freien in einem breiten Temperaturbereich eingesetzt werden. Unter Temperaturbedingungen von bis zu –20 °C war aufgrund bisheriger Werkstoffkonzepte bei Hydraulikzylindern Sprödbruchneigung mit der Gefahr von Personen‐ und ...

Position Sensors for Hydraulic Cylinders

SAE Technical Paper Series, 1993
<div class="htmlview paragraph">There are several types of transducers that can be used to measure piston position of a fluid power cylinder. This paper discusses and compares four sensing technologies; encoder, magnetostrictive, potentiometer, and inductive. Application concerns are also discussed.</div>

Orthotropic hydraulic permeability of arrays of parallel cylinders

Physical Review E, 2017
Approximate analytical methods are presented to calculate the overall orthotropic hydraulic permeability of a flow with low Reynolds number, passing through a bundle of parallel circular cylinders. Two particular distributions are considered: (i) arrays with ordered rectangular lattices and (ii) irregular nonrandom distributions for which the unit cell
