DC Series High Force Vibration Shaker


A water-cooled electrodynamic shaker is a specialized testing device used to subject objects to mechanical vibrations. It is commonly employed in various industries, including automotive, aerospace, electronics, and military, to simulate real-world conditions and assess the performance, durability, and reliability of products or components.

Here's how a water-cooled electrodynamic shaker typically works:

  • Electrodynamic Principle:

    The shaker consists of a voice coil, a magnet assembly, and a suspension system. When an alternating electrical current flows through the voice coil, an electromagnetic force is generated, causing the voice coil to move in response to the magnetic field created by the permanent magnets. This motion generates vibrations that are transmitted to the object being tested.

  • Cooling System:

    To dissipate the heat generated during the testing process, water cooling is employed. The shaker is designed with channels and passages through which water circulates to absorb and carry away the heat. This ensures the shaker remains within its operating temperature limits, allowing for extended testing periods and preventing overheating.

  • Control and Monitoring:

    The shaker is typically equipped with a control system that allows precise adjustment of the vibration parameters, such as frequency, amplitude, and waveform. Sensors are employed to monitor and measure the generated vibrations, providing real-time feedback to ensure accurate and consistent testing.

  • Fixturing and Load Attachment:

    Objects to be tested are securely mounted on a fixture or platform, which is then connected to the shaker using appropriate load attachments. The load attachments can vary depending on the type and size of the object being tested, ensuring proper transmission of vibrations and preventing any damage or displacement during the test.

Advantages of water-cooled electrodynamic shakers include:

  • Higher Power and Force:

    Water cooling allows for higher power and force capabilities, enabling the shaker to produce stronger vibrations. This is particularly beneficial when testing larger or heavier objects or when replicating severe environmental conditions.

  • Extended Testing Time:

    The cooling system helps maintain the shaker's temperature, allowing for prolonged testing periods without overheating. This is advantageous when performing endurance tests or when evaluating long-term product performance.

  • Improved Testing Accuracy:

    Consistent and controlled temperature conditions contribute to more accurate and repeatable test results. The cooling system helps minimize thermal variations that could affect the behavior and response of the tested object.

  • Enhanced Reliability:

    By preventing overheating and managing temperature fluctuations, water cooling contributes to the overall reliability and longevity of the shaker, ensuring its continuous operation over extended periods.

It's important to note that specific details and capabilities of water-cooled electrodynamic shakers may vary depending on the manufacturer and the intended application. Please contact us for more details.
