Vibration Site Survey and Analysis

Quantifying and analyzing the vibration and shock criteria existing at a present or proposed installation site for precision equipment such as a precision machine tool, CMM or other equally sensitive machine is recommended to assure long term accuracy and reliability.

Low frequency vibrations can adversely affect the accuracy, repeatability and throughput quality of your precision machinery. A vibration site survey/analysis report will determine the frequency content of vibration amplitudes which exceed the allowable floor vibration specification for your machine(s). Most precision machine tool and measuring machine manufacturers have established allowable vibration specifications for their machines. Fabreeka® measures vibration at the proposed site(s) of your installation, analyzes the data and presents the results in the specified format. Measurements will be made in three (3) axes simultaneously, using highly sensitive seismometers which can accurately record amplitudes of vibration at very low frequencies.

Measurement data includes:

• Fast Fourier Transform spectral analysis (bandwidth per manufacturers specifications)
• Displacement data
• Velocity data
• Acceleration data
• Power Spectral Density (energy content at each frequency within the specified bandwidth)
• In all three primary axes simultaneously

Special Site Vibration Surveys

Fabreeka® is often asked to perform measurements which require special data analysis, including tip and tilt phenomena, foundation/isolation system natural frequencies, long-duration time studies and other specialized analyses. We welcome, in fact, encourage requests for unique measurement requirements. It is better to be absolutely certain of all possible conditions that could impact a site before equipment is installed.

Service

Analyses include actual test data outlining the frequency and corresponding amplitude of acceleration, velocity and displacements which may cause potential problems. Analysis of data from vibration measurements enables computer matching of measurements results with Fabreeka's® isolation database. Problem situations are identified, and the appropriate isolators or systems are selected. We have established a structured sensor calibration and equipment upgrade program to ensure state-of-the-art measurement reliability and accuracy. Please contact Fabreeka® to request a brochure.
