Vibration Monitoring and Analyses

Service Overview

Experimental dynamic/vibration measurements have many applications. A major reason for vibration testing of a structure or machine is to determine its natural frequencies— those of which are extremely important in predicting and understanding a system’s dynamic behavior.

Results from vibration tests can be used to verify an analytical model (such as a finite element model) and to calibrate dynamic material properties. Vibration testing is also used in machinery diagnostics for maintenance.
