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.

Multiobjective Hydraulic Cylinder Design

Journal of Mechanisms, Transmissions, and Automation in Design, 1988
Monotonicity analysis is used to solve a three-objective optimization problem in which a hydraulic cylinder is to be designed. With the additional application of the Karush-Kuhn-Tucker optimality conditions a reduced symbolic design chart is obtained which is then utilized to obtain parametric numerical results.

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 ...

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>

Dynamic analysis of hydraulic cylinder

2021
Many machines and machine mechanisms run under dynamic working conditions. The vibrations produced under dynamic conditions affect many important design parameters such as strength, production costs, productivity. In this thesis, the vibration analysis of a hydraulic cylinder subjected to dynamic loads is studied.

Hydrogen Embrittled Hydraulic Cylinders

2019
Abstract Two types of chromium-plated hydraulic cylinders failed by cracking on their outer surfaces. In one case, the parts had a history of cracking in the nominally unstressed, as-fabricated condition. In another, cracks were detected after the cylinders were subjected to a pressure impulse test.
