Electrodynamic Shaker System
Advanced Electrodynamic Shaker Systems for Controlled Vibration Testing
Electrodynamic Shaker Systems are widely used for controlled vibration testing of components, assemblies and products. These systems help engineers reproduce defined vibration conditions in a laboratory to evaluate product durability, reliability and performance.
At SDYN, we design and manufacture Electrodynamic Shaker Systems for applications across aerospace, automotive, defense, electronics, battery, railway, research and industrial sectors. Our systems can be configured according to force, frequency range, displacement, velocity, payload and testing requirements.
What Is an Electrodynamic Shaker System?
An Electrodynamic Shaker System uses electromagnetic force to generate controlled mechanical vibration. The shaker receives signals from the vibration controller and power amplifier and converts them into precise mechanical motion.
A complete Electrodynamic Vibration Shaker System may include:
- Electrodynamic shaker
- Power amplifier
- Vibration controller
- Accelerometers and sensors
- Horizontal slip table
- Head expander
- Vibration isolation system
- Test fixtures
These components work together to provide controlled and repeatable vibration testing.
How Does an Electrodynamic Shaker Work?
An Electrodynamic Shaker generates vibration by using electrical current and a magnetic field to create controlled force on the armature.
The vibration controller generates the required test signal, while sensors monitor the actual response of the test specimen. The controller continuously adjusts the input to maintain the required test profile.
Test Profile → Controller → Power Amplifier → Shaker → Test Specimen → Sensors → Feedback
This closed-loop process allows engineers to perform controlled vibration tests with measurable and repeatable results.
SDYN Electrodynamic Shaker Systems
SDYN provides Industrial Electrodynamic Shaker solutions that can be integrated with different testing components according to the application.
System selection depends on important parameters such as:
- Force rating
- Frequency range
- Acceleration
- Displacement
- Velocity
- Payload
- Armature size
- Test orientation
- Cooling requirements
- Required vibration profile
This allows the Electrodynamic Shaker Machine to be configured according to the actual testing requirements rather than using a standard setup for every application.
Key Components of a Vibration Shaker System
Electrodynamic Shaker
The shaker is the main excitation unit that generates controlled vibration. Its capacity is selected according to the required force, payload, acceleration and frequency range.
Power Amplifier
The power amplifier supplies the electrical power required to operate the shaker and works with the controller to generate the required vibration profile.
Vibration Controller
The controller generates and manages test signals while monitoring feedback from sensors. Depending on the configuration, it can support testing methods such as sine and random vibration.
Horizontal Slip Table
A horizontal slip table enables horizontal-axis vibration testing and is useful when the test specimen needs to be evaluated in different orientations.
Head Expander
A head expander provides a larger mounting surface for testing larger components or assemblies.
Air-Cooled and Water-Cooled Shaker Systems
SDYN vibration testing solutions can be configured with different cooling arrangements according to system requirements.
Air-Cooled Electrodynamic Shaker: Uses forced air for thermal management and can be suitable for a range of vibration testing applications.
Water-Cooled Electrodynamic Shaker: Uses a water-based cooling arrangement for applications requiring enhanced thermal management during demanding testing conditions.
The appropriate cooling configuration depends on factors such as force level, test duration, operating conditions and application.
