What Causes High Vibration Levels?

The majority of machinery in manufacturing processes employ vibrating or rotating principles to perform their operating role within the plant. Industrial equipment such as vibrating screens, vibrating feeders, crushers, grinders and vibratory centrifuges are good examples. For such equipment, high vibration levels from the operating process is likely to be transmitted to the supporting structure or adjacent machinery.

Vibratory resonance is the main cause for large vibration levels and it could lead to significant damage or even failure of the equipment and supporting structures. Additionally, such resonance condition causes increased noise levels leading to considerable human discomfort.

Vibration Control and Mitigation

An accurate vibration analysis is the first step to reducing high vibration levels affecting a system. If the vibration problem affects an existing machine or structure, a measurement campaign is first conducted in order to determine the vibrational state of the system. A vibration analysis of the measurements will highlight the correct path towards an appropriate solution.

Advanced computational techniques, such as Finite Element Methods, are then required to compute the resonance condition and the dynamical system’s response due to the excitation source. This type of computation provides a detailed characterization of the vibrational and dynamical behavior in order to identify vibrational issues and propose efficient mitigation solutions.

Product Design Consulting

During the design phases of product development, engineers need guidance on the vibration levels of their future product in order to comply with regulations while meeting customer expectations. Engineers also need to investigate and optimize the performances of different designs to achieve their target. Prototyping and experiments can be used to estimate vibration levels in your design. However, in large-scale systems, this approach can be costly and in the worst cases can be impossible to build it. In such cases, advanced computational techniques, such as Finite Element Methods, not only provide an accurate assessment of vibration levels, but also allow the exploration of solutions that may not have been accessible through experiments.
