Designed for Large-Scale Reliability Testing

As modern engineering products become larger and more complex, vibration testing systems must deliver higher force output, greater payload capacity, and better thermal stability. Traditional air-cooled systems may struggle to maintain stable performance during long-duration or high-power tests.

The EDH Series Water-Cooled Electrodynamic Shaker System is designed to meet these challenges. With a force range from 80 kN to 200 kN, the system provides powerful excitation capability and superior cooling efficiency, making it ideal for testing large components and full assemblies.

Key Summary:
Force range up to 200 kN, payload up to 2000 kg, water-cooled design, low noise operation, and high reliability for demanding vibration testing applications.

Efficient Water Cooling for High-Power Operation

Efficient thermal management is essential for high-force vibration testing. The EDH Series adopts a water-cooling system that significantly improves heat dissipation compared with conventional air-cooled designs.

• Water-cooled structure for low noise and high power output

• Superior heat dissipation performance

• Typical moving coil operating temperature around 50°C

• Micron-level water filtration system to prevent clogging

• Advanced sealing and welding technology to eliminate water leakage risks

This ensures stable operation even during long-duration or high-load vibration tests.

High Structural Stiffness and Dynamic Performance

The EDH Series incorporates advanced mechanical design to ensure high dynamic performance and structural reliability.

• High-stiffness moving coil skeleton for higher first-order resonant frequency

• Double magnetic circuit design for uniform magnetic field and low flux leakage

• Advanced moving coil cooling method with parallel excitation waterway

• Improved cooling efficiency and operational reliability

These features allow accurate reproduction of vibration environments while maintaining excellent system stability.

Heavy Payload Capacity and Strong Guidance System

Large test specimens require stable guidance and high anti-overturning capability. The EDH Series integrates robust structural solutions to support heavy payload testing.

• Upper and lower roller guidance structure

• Optional hydrostatic bearing guidance for precision motion

• Maximum payload up to 2000 kg

• Strong anti-overturning torque capability

This enables safe and reliable testing of large assemblies and heavy equipment.

Advanced Isolation for Laboratory Stability

To minimize vibration transmission to surrounding structures and equipment, the EDH Series incorporates advanced isolation technologies.

• Air-spring trunnion isolation system

• Excellent vibration isolation capability

• Reduced vibration transmission to laboratory floors

• Improved operational safety and measurement accuracy
