Hydraulic Vibration Testers

Product catalog summary

Overview: The HV SeriesTM Test Systems are designed for hydraulic vibration testing, offering high performance and reliability. These systems are suitable for various test types, including sine, random, resonance search and dwell, sine-on-random, random-on-random, KurtosionTM, and classical shock tests.

Key Components:

1-G Supports: Reduces load on the actuator and prevents table rotation during operation.
Air Bag Isolators System: Isolates vibration between the system and foundation.
Accumulator Assembly: Ensures a constant and smooth fluid supply to the actuator.
Hi-Performance Tables: Made from aluminum alloy or magnesium for rigidity and uniformity.
Hydrostatic Bearing Actuator: Self-centering with no piston rings, providing long life and minimal maintenance.
Servo Valve: Regulates fluid flow and frequency through the actuator.
Reaction Mass: Provides system stability and minimizes velocity loss at low frequencies.

Performance Specifications:

Frequency range from 1Hz to 500Hz.
Actuator warranty of 3 years.
System selection based on test item size and weight, with servo-hydraulic systems recommended for larger payloads.

System Sizing and Selection:

Determine table size based on the largest test item.
Reaction mass should be 2-3 times the combined weight of the table and test item.
Actuator sizing based on weight and acceleration requirements.
Servo-valve and hydraulic power supply sized according to actuator flow requirements.

Control System:

Includes accelerometers, vibration controller, and servo controller for closed-loop control.
Supports sine and random testing, with optional features like kurtosis control.

Optional Features and Services:

Stacking fences, additional monitoring channels, and increased system performance options.
Software control modules for field data replication.
Preventive maintenance agreements and extended warranties available.
On-site operator training and laboratory certification services.

Technical Specifications:

Vertical and horizontal table sizes available, with maximum payload weight of 5,000lbs.
Hydraulic power supply options from 7.5HP to 120HP.
Servo valve flow options from 5 gpm to 50 gpm.

Utilities:

Hydraulic power supply requires 380V/3Ph/50Hz or 460V/3Ph/60Hz.
Vibration and servo controllers require 115V/1Ph/60Hz or 220V/1Ph/50Hz.
Compressed air and tap water requirements for system operation.

Included with Each System:

Pre-installation documentation, operation manuals, on-site training, and a full warranty.
Software updates for one year.
