Characterizing the dynamics of components with ease

Modal Analysis is a specialized product option for VibeSys for characterizing the dynamics of a machine or structure in terms of its dynamic properties. It enables engineers to determine modal frequencies, modal damping ratios, and mode shapes at a specific frequency. FE results may be validated by comparing modal frequencies to mode shapes with experiemental tests to achieve a high quality results prior to physical testing.

Accelerate tests without exceeding realistic levels

Vibration Profile Design provides the ability to create accelerated shaker tests based on equivalence of fatigue damage or shock. It provides a documented, repeatable process for developing vibration profiles from time histories, PSDs or a mix of both before physical parts are made, saving both time and money in environmental qualification and product validation.
