HV-Series: Hydraulic Vibration Testers

What Is A Hydraulic Vibration System?

• An L.A.B Hydraulic System is a rigid table surface supported and driven by a closed-loop servo controlled hydraulic actuator.
• The system is capable of producing single axis vibration at controlled levels of displacement, velocity or acceleration throughout a specific range of frequencies.

Standard System Components

• Vibration Table
• Actuator/Piston Assembly
• Hydraulic Power Supply
• Hydraulic Manifold
• Servo Valve
• LAB Motion Controller HSC Servo Controller
• Lynx™ Digital Vibration Control System
• 1-G Supports (48” and Larger)

Vibration Table

• Actuator/Piston Assembly
• Hydraulic Power Supply
• Hydraulic Manifold
• Servo Valve
• LAB Motion Controller HSC Servo Controller
• Lynx™ Digital Vibration Control System
• 1-G Supports (48” and Larger)

Hi-Performance Tables

• Aluminum alloy or magnesium table weldments provide the most rigid tables for higher frequency testing and superior uniformity, unmatched in the industry.

Accumulator Assembly

• Pressurized gas bladders help provide a constant and smooth supply of fluid to the actuator.

1-G Supports (as needed)

• Reduces load on actuator by 1g of acceleration. Also provides anti-rotation of table during operation. Not used on smaller tables.

Hydrostatic Bearing Actuator

• State-of-the-art hydrostatic bearing actuators are self-centering, with no piston rings or hi-pressure seals providing long-life with little maintenance. This means unsurpassed control & balance for off-centered loads.

Servo Valve

• We use industry standard valves to regulate how much (displacement) and how fast (frequency) high pressure fluid needs to flow through the actuator.

Reaction Mass

• Solid steel mass mounted on a damped air-mount suspension provides highest possible system stability and minimal velocity loss at low frequencies.

Air Bag Isolators System

• Isolates vibration between the system and your foundation during operation.

Performance

• Down to 1Hz, up to 500Hz.

Installation of L.A.B HV Systems
As L.A.B HV Vibration systems are varied in capabilities and intended use, so will the installations. Systems being installed in Asia, the USA or Europe all will have different facility, safety and usability constraints. L.A.B Equipment will guide you through the process to make sure your installation is the best it can be.

Will will guide you through the process giving you the details you need regarding:

Flooring Requirements
Utility Requirements
Spacing and optimum workspace
Mounting the equipment
Safety requirements
Equipment and tools needed by the customer for installing and positioning the equipment

Test Fixture

• Set allows easy specimen attachment to the vibration table.

Stacking Fences

• Maintain shipping container alignment during testing.

Custom Systems

• heavier payloads
• larger displacement or velocity
• broader frequency range
