"So the question is on the table. Should we use an external laboratory to do our vibration tests or purchase equipment and do the work in-house?

Sine tests are a popular method to simulate real-world vibration because most rotating machinery creates vibrations of a sinusoidal nature. When shakers vibrate according to a Sine profile, they reflect the types of vibrations often found in automobiles, airplanes, factories, and many types of pumps and engines.

Anyone who has lived or worked at or near a construction site is familiar with the sound of pile driving, or the mechanical driving of specialized poles into the earth to provide foundational support for buildings. The noise and vibrations of the work may continue at high decibels over a prolonged period of time.

It is not easy for human eyes to see the modal shape at various frequencies. If we can freeze the motion at the desired frequency, we can capture the modal shape created. A stroboscope is a device which flashes light at a resonance frequency of an object to make the object appear stationary.

Modal testing is a common method to determine the characteristics of an object through exciting the structure to a certain vibration level and obtaining its resonance frequencies. It is important for a brake system to keep vibration under control during operation because excessive vibration while braking could cause driver discomfort, premature and irregular tire wear, and stress on steering and suspension components.
