Vibration Analysis

Vibration analysis is used throughout the world in industries ranging from aerospace and defence, to the development of the latest smartphones. By harnessing vibrations, we can gain great insight into the inner world of products, machines, and structures.

Material stress and health monitoring

As vibrations move and shake objects, they stress their materials and construction. So, vibration testing can reveal how likely a product is to fail in real life and how much abuse it can withstand. Vibrations can indicate weak points in a product, demonstrate how much force it takes to break it, or simulate the product’s lifetime in just a matter of hours.

“Listening” to the dynamic response

The inner world of structures, such as automotive components, is a vital place to investigate vibrations. Insights to how parts respond to forces in the real world, is done via vibration excitation which creates a dynamic response, we can ‘listen’ to and use to discover the inherent structural dynamics and health. These are the properties that, for example, will produce noise and vibration in a vehicle, or more seriously; can create weak points in an aircraft.

Gaining practical knowledge

Even without ‘exciting’ a product, we can learn about it by ‘listening’ to vibrations. Vibration analysis can show us how well balanced an automotive brake disc is: whether it’s good enough to be put on a car and trusted to stop it in an emergency. Measuring the vibrations generated during the operation of a product – from a wind turbine blade to a vehicle gearbox – can reveal issues within it and locate their origins.

Whether you want to generate external vibrations to test product integrity, or to analyze and engineer the vibrations your products themselves make, Brüel & Kjær can provide a system, training and service – from vibration exciters to data acquisition and analysis.
