Raagen offers advanced solutions for all varieties of material testing, including monotonic and cyclic testing. Backed by more than 10 years of experience, Raagen provides the technology and the specialized expertise to perform accurate, repearable tests that ensure materials and components meet standards. These complete solutions for Hydrostatic Actuators include:

  • Highly stiff, floor standing servo hydraulic load frames for a range of force requirements,
  • Test benches to achive custom design tests for construction, automotive and rail materials,
  • Aplicable, versatile and user friendly material testing software with powerful test design capabilities,
  • Digital controllers with high channel density, high capacity and superior configurability,
  • Rugged, high performance test grips and test fixtures for servo actuators.

 

Overview

Raagen hydraulic servo cylinders are the workhorse of any laboratory and facility. They can perform a wide variety of low and high cycle fatigue, crack propagation, fracture toughness, construction, seismic and other synamic test applications. Each system can be rigitly configured with appropriate sized servo valves, manifolds and hydraulic power unit to suit the particular application. All systems are equipped with the advanced features of hydraulic power unit to suit the particular application. All systems are equipped with the advanced features of the Doli EDCi controllers, console software and unique fatigue rated load cells. Test&Motion Dynpack dynamic testing software provides the backbone for running many dynamic tests. Other applications specific software module allows other standardized tests to be run. These dynamic systems, when combined with Test&motion and appropriate accessories are ideal for also running variety of static tensile, compression, flexure, peel, tear and friction tests.

Features of Raagen Hydrostatic Linear Actuators

  • Raagen Hydrostatic Actuators are using for precise control of high- frequency motions and forces.
  • They are double-ended, linear force generating actuators that operate under precision servo valve control.
  • The test actuators are designed specifically as low friction, low distor- tion, high sideload for dynamic testing of structures and components.
  • Hydrostatic pressure-centering bearings are existing for continuous high speed operation under heavy side loaded conditions.
  • Raagen test cylinders have large-diameter, single-piece, chrome-plated piston rod provides strength and lateral stiffness.
  • These actuators feature fatigue-rated designs to exceed rated loads for millions of cycles. You can expect highly reliable performance over a long functional life, helping to maximize your uptime and mi- nimize total cost of ownership.

Content of Hydrostatic Actuator Systems:

  • High technology fatigue rated loadcell that has high accuracy from 0,01% to %0,5.
  • High reponse or very high response servo valves with suitable flow rates of HPU's.
  • High precison position measurement sensors.
