Vibration testing tables are essential for industries that rely on ensuring the stability and reliability of their products under various vibrational conditions. This article aims to delve deeper into the subject, offering a comprehensive overview of vibration testing tables, their functionalities, and applications.

What is a Vibration Testing Table?

A vibration testing table, often termed as a shake table, is a device that can create controlled vibrations. It serves to simulate real-world vibration conditions in a controlled setting. The table can subject a specimen, usually a product or a model, to specified vibration patterns and frequencies, allowing researchers and engineers to assess its response and resilience.

Why is a Vibration Testing Table essential?

Vibration can be a significant factor affecting the life and functionality of a product, especially those exposed to varying environmental conditions. By understanding how a product reacts to different vibrational conditions, industries can ensure they produce durable and reliable items.

  • Ensuring Product Durability

Products that are not tested for vibration resilience might fail when exposed to real-world conditions. Such failures can lead to significant financial losses and, in some cases, can even be dangerous.

 

  • Complying with Industry Standards

Many industries have strict standards regarding how products should perform under certain conditions. Vibration testing ensures that products meet these standards, ensuring safety and reliability.

Types and main features of Vibration Testing Tables

There are various types of vibration testing tables, each catering to specific testing needs:

  • Electrodynamic Tables

These tables use an electromagnetic field to produce vibrations. They are known for their precise control over frequency and amplitude.

  • Hydraulic Tables

Using fluid dynamics, these tables can generate more substantial and more aggressive vibrations, making them suitable for heavy-duty testing.

Vibration testing tables come in various sizes and capacities. However, some essential features are common across most high-quality tables:

  • Frequency Range: The range of frequencies the table can produce.
  • Acceleration: Measures how quickly the table can change its speed.
  • Payload Capacity: The weight the table can handle.

Applications of Vibration Testing Tables

Vibration testing tables find applications across several industries, ensuring that products can withstand the rigors of their intended environments.

Aerospace and Defense

In these industries, ensuring that components can endure vibrations during launches or flights is critical. A vibration testing table can simulate these conditions, ensuring components won’t fail when in use.

Automotive

Cars, trucks, and other vehicles are subjected to various vibrational forces when in use. Testing ensures that every part, from the engine to the smallest bolt, can withstand these forces.

Electronics

Electronic devices, especially portable ones, are frequently subjected to shakes and vibrations. Testing ensures these devices function correctly under such conditions.

Civil engineering

Civil engineers use vibration testing to identify potential structural flaws in bridges, buildings, and pipelines.

Consumer goods

Household products need to withstand the demands of everyday use. Vibration testing helps establish the limits of these products and ensure their safety for end users.

Defense

By utilizing vibration testing, defense manufacturers can ensure that equipment and weapons systems are safe to transport and effective in combat situations.

Equipment maintenance

Vibration testing allows you to monitor the condition of industrial machinery and all its parts, including complex components like meshing gear teeth, combustion equipment, and rotating shafts.

Medical equipment manufacturing

Hospital equipment failure is literally a matter of life and death. By testing products before release, manufacturers can prevent failures in critical life-saving equipment.

US important Vibration Test Standards

Different sectors and standards-setting bodies have established vibration testing guidelines and norms to delineate acceptable outcomes. A few prominent standards encompass:

  • MIL-STD-810: Method 514 from this American military standard, revised in 2019, lays out the endorsed vibration test techniques for durable equipment.
  • ISTA Testing Protocols: Schemes from the International Safe Transit Association (ISTA) aim to guarantee products’ resistance to the sporadic high-frequency pressures during transportation.
  • ISO 10816: An ordinance from the International Organization for Standardization (ISO), this standard focuses on the criteria related to vibration testing across diverse sectors.

Rotational Vibration Testing

The Rotational Vibration Table is specifically engineered for conducting low-vibration shock tests in compliance with ASTM D999-08, ISO 2247:2000, and ISTA protocols. Its user-friendly control system empowers you to select from a variety of vibration test modes. Additionally, this vibration system is equipped with an easy-to-use control panel and an automatic table leveling system for added convenience.

Motovibration Vibration Testing

The Motovibration Testing System provides numerous benefits, including minimal transverse vibration interference, an automatic table leveling feature, objective data gathering via a built-in vibration sensor, user-friendly software, accessibility for testing novices, and minimal maintenance demands.

Another of the most innovative pieces of equipment designed  to simulate real vibrations in the distribution cycle,  is the multi-axial or tri-axial vibration equipment, the Vertical Vibration + Pitch & Roll System.

Vertical Vibration Testing with Pitch and Roll Module

Thanks to the patented pitch and roll module technology, the Vertical Vibration table has been upgraded to include pitch and roll motions, accurately replicating the conditions experienced by the load during handling and transportation.

The multyaxial system is able to reproduce the vibration forces of  diffrents transportions modes, such as road, train or plane:

  • Vertical frequency ranges up to 200 HZ.
  • P&R frequency range up to 25 Hz.
  • P&R rotation ± 5º.
