Vibration Measurement

Vibration for Sensitive Equipment

Some scientific instruments are very sensitive to vibration. Examples include lasers, magnetic resonance imaging (MRI) or computed tomography (CT) scanner etc. These must be installed in environments where the vibration levels are exceptionally low.

There are no national or international standards which apply, but a number of Vibration Criteria (VC) curves have been devised over the years for acceptable levels in different environments.

If you are planning on installing sensitive equipment, our vibration specialist can use the latest technologies for vibration measurement as well as data analysis. The measured vibration levels will be compared with the vibration criteria, we use our extensive experience to determine whether the vibration levels are acceptable or excessive.

Impact Test & Forced Vibration Test

Open and large column-free spaces are the trend of modern construction design, for example, stadium, luxury lobby, etc. However, this design may create serviceable problem such as nuisance and discomfort to the users.

Our vibration specialist can use the latest technologies for vibration measurement as well as data analysis to determine whether the vibration levels are acceptable or excessive. We can perform impact and forced vibration tests to determine the modal properties of the floor system and in conjunction with walking tests can determine the floor vibration response including its fundamental frequency, peak acceleration, rms acceleration and velocity, and VDV.
