In various industries, from electronics to aerospace, the need for precise and reliable vibration testing is ever - present. Our innovative Small Electrodynamic Shaker equipped with a Head Expander has been specifically engineered to perform sine dwell vibration testing with utmost accuracy, offering a valuable solution for evaluating the durability and performance of components and products.
1. Understanding Sine Dwell Vibration Testing
Sine dwell vibration testing involves subjecting a test specimen to a continuous sinusoidal vibration at specific frequencies for a set period. This type of testing is crucial for identifying the resonant frequencies of components, as well as assessing their ability to withstand sustained vibrations at those frequencies. Resonance can cause excessive stress on components, leading to fatigue, failure, or malfunction. By conducting sine dwell tests, manufacturers can pinpoint these critical frequencies and make necessary design improvements to enhance product reliability.
2. Key Features of Our Small Electrodynamic Shaker with Head Expander
Compact and Portable Design
The small size of our electrodynamic shaker makes it highly suitable for use in laboratories with limited space, as well as for on - site testing. Despite its compact dimensions, it doesn't compromise on performance. It can be easily transported and set up, allowing for flexibility in testing locations. The shaker's design also ensures that it can be integrated into existing testing setups without significant modifications.
Head Expander for Enhanced Testing Capabilities
The integrated head expander is a unique feature of our shaker. It allows for the connection of multiple test specimens simultaneously, expanding the scope of testing. This is particularly useful when conducting comparative tests on different components or when testing a group of related parts. The head expander is designed to distribute the vibration evenly across all connected specimens, ensuring consistent and accurate results.
Precise Sine Dwell Vibration Generation
Our shaker is equipped with advanced technology that enables it to generate highly accurate sinusoidal vibrations. The frequency range typically spans from 5 Hz to 4000 Hz, covering a wide spectrum of frequencies relevant to various industries. The amplitude of vibrations is precisely controllable, with a maximum acceleration of up to 100 g and a maximum displacement of ±20 mm. This precision ensures that test specimens are subjected to the exact vibration conditions required for sine dwell testing.
Customizable Test Profiles
We understand that different components and products may require unique testing conditions. Our shaker allows for the creation of highly customizable test profiles. Engineers can set the specific frequency, amplitude, and dwell time according to the requirements of the test specimen. Whether it's a short - term, high - intensity test at a specific frequency or a long - term, low - amplitude endurance test, the shaker can be programmed to meet the exact needs of each test.
User - Friendly Control System
The shaker features a user - friendly control system that is PC - based. The intuitive software allows operators to easily input test parameters, start and stop the test, and monitor the progress in real - time. The software provides clear visual displays of key data such as vibration frequency, amplitude, and dwell time. It also has comprehensive data - logging and analysis capabilities, enabling the collection and in - depth evaluation of test data for a thorough assessment of component performance.

4. Applications
Electronics Industry
In the electronics industry, our small electrodynamic shaker is used to test components such as circuit boards, connectors, and sensors. By subjecting these components to sine dwell vibrations, manufacturers can identify potential weaknesses in the design, such as loose connections or components that are prone to resonance. This helps in improving the reliability of electronic products and reducing the risk of in - field failures.
Automotive Industry
Automotive components, including engine parts, suspension components, and interior trim, are tested using our shaker. Sine dwell testing can reveal how these components respond to specific vibration frequencies, which is crucial for ensuring a smooth and quiet ride. It also helps in detecting any potential failures that could occur due to resonance during normal vehicle operation.
Aerospace Industry
Aerospace components, such as avionics systems and structural parts, are highly sensitive to vibrations. Our shaker is used to perform sine dwell tests to ensure that these components can withstand the vibrations experienced during flight. By identifying and addressing resonance issues, aerospace manufacturers can enhance the safety and reliability of their aircraft.
