Vibration Analysis for Predictive Maintenance

Our vibration analysts can determine stress points in your equipment and structures. We can also predict failures and recommend preventive measures and design improvements, as required.

DTB’s finite element analysis (FEA) method is used to model the structural dynamic characteristics of vibrations within a mechanical system – the understanding of which is vital to any root cause failure study involving excessive vibrations. The use of vibration analysis and FEA techniques to evaluate the dynamic characteristics of machines and structures prior to fabrication is also important.

Simulated FEA models are used to approximate stress stiffening effects in rotating mechanical components. The FEA analysis models are used to approximate the natural frequencies and mode shapes of complex structural-mechanical systems. FEA techniques can also model the response of your equipment or structure to dynamic loads. DTB’s vibratory testing facilities can simulate vibration and shock responses from a shaker table on a structural component.

We take pride in our ability to develop models that are only as complex as necessary in order to resolve the problem in a timely manner.
