The term dynamic FEA relates to a range of powerful simulation techniques that can be applied to even complex engineering systems.  Dynamic analysis is typically used to design out potential noise and vibration problems, or to evaluate the impact of transient loads.

As experienced development engineers our contribution to a dynamic evaluation rarely stops at the analysis output.  We routinely work alongside clients to find design solutions that are realistic and offer genuine commercial benefits:

• Reduced requirement for expensive testing.
• Elimination of expensive mistakes at the design stage.
• Anticipation of noise and vibration problems.
• Avoidance of unexpected failures.

Modal analysis is used to identify natural frequencies, and enables the designer to avoid excitation and eliminate excessive vibration.  Animations are easily produced to provide valuable insight into how the structure will behave when excited.

Harmonic response analysis is used to determine the steady-state response of a linear structure to sinusoidal loads, and enables the evaluation of resistance to sustained forced vibration.

Transient dynamic analysis is used to determine the response to general time-dependent loads. Typical applications include seismic or explosive events.

Rotordynamic analysis is important when designing or troubleshooting rotating systems. By modelling the rotating geometry and its dynamic characteristics, such as stiffness and damping, the critical speeds can be predicted. Design adjustments can then be made to avoid continuous running at those speeds.

TriVista Engineering offers a range of analysis options, and the integration of FEA with our other services enables a complete engineering package when required.
