Vibration analysis and dynamic balancing are a key part of any plant maintenance program.

Vibration Analysis and Dynamic Balancing: Enhancing Comfort and Longevity


In today’s fast-paced world, it’s not uncommon for commercial offices and residential buildings to accommodate complex plant systems and rotating equipment in close proximity to tenant spaces. While this integration is essential for modern living, it inadvertently leads to the transmission of vibrations into these spaces. Prolonged exposure to these vibrations can result in discomfort, health concerns, and even premature aging of machinery. In scenarios like apartment buildings, noisy plant equipment can disrupt peaceful nights, robbing residents of essential sleep.

Understanding the Impact of Vibration:

Vibration is an inherent aspect of the machinery world – everything vibrates to some degree. However, it’s critical to minimise these vibrations to enhance quality of life, extend machine lifespans, and address various factors linked to structural vibration within buildings.

Vibration possesses three primary properties: acceleration, deflection, and amplitude. Excessive vibrations can lead to numerous issues, including misalignment in rotating shafts, imbalance in fans, and improper mounting of fans and pumps. These problems can transmit vibrations into the building structure, manifesting as noise.

The Role of Vibration Analysis:

What is a vibration analysis?

Vibration analysis provides a comprehensive approach to diagnosing and mitigating vibration-related problems. This method entails analysing machinery vibrations across the entire spectrum.

Why do we need vibration analysis?

While it’s impossible to entirely eliminate vibrations, it’s essential to understand and control them. Vibration analysis is the key to achieving this understanding.

What can be detected through vibration analysis?

Through vibration analysis, the source of the issue, whether it’s caused by imbalance, misalignment, or gear mesh frequencies, can be accurately pinpointed.

What are the steps in vibration analysis?

Vibration analysis can even differentiate vibrations arising from various parts of a bearing, including the cage, outer raceway, and inner raceway. In scenarios where gear mesh frequencies cause vibrations under heavy loads, like on-site concrete mixers, vibration analysis can efficiently locate the source, saving valuable time that would otherwise be spent speculating.

The Role of Vibration Analysis:

Vibration analysis is invaluable for critical equipment and is best employed during the commissioning stage to establish a baseline vibration level. Over time, continuous monitoring helps track trends indicating machinery degradation. By identifying these trends, repairs can be planned and executed before catastrophic failure occurs.

What is the difference between static balancing and dynamic balancing systems?

Static Balancing:

Static balancing is performed using low friction bearing to suspend the shaft or axis point and through gravity the heaviest section of the rotating section will rotate to the bottom and weight is added to the lightest part (or weight removed from the heaviest) until the rotating item runs on its axis and does not fall to the same position and does not spin without assistance.

Most fan manufacturers use this static balancing technique with reasonable success, however, when run at speed, these can easily exceed 1 mm/sec (in some cases much higher).

Dynamic Balancing:

The same Vibration Analysis equipment used for vibration analysis is ideal for dynamic balancing. For instance, in a ventilation fan scenario, balancing can occur in single or multiple planes, effectively eliminating the vibrations that manifest as noise. This process not only enhances occupants’ comfort but also extends the equipment’s lifespan.

Isolation Techniques:

In addition to vibration analysis and dynamic balancing, Quantum Plant Maintenance employs isolation techniques, including proper mounting methods with spring mounts and rubber mounting methods using double and triple oscillation pads. These methods significantly reduce vibration transmission into the building structure, effectively eliminating noise.

Our Success Stories:

Quantum Plant Maintenance boasts a history of successful projects that have significantly improved the workspaces of office environments and the living conditions of high-rise apartment dwellings. In scenarios where tenants and facilities management have sought relief from noise complaints through council engagement, our services have been pivotal in identifying and mitigating vibrations, bringing them to acceptable levels in line with council guidelines and the well-being of tenants.
