Modal Testing

Mechanical Solutions, Inc. uses the latest hardware and software combined with the Time-Averaged Pulse (TAP™) technique to quickly determine possible modal problems. The TAP™ technique allows MSI to test your equipment while you stay online! Modal visualization and Structural Dynamic Modification (SDM) software are utilized to determine the best corrective action. MSI couples real world modal test data with Finite Element Analysis (FEA) to provide calibrated analytical models which can be used to perform "what if" analyses.
