Dynamic Analysis

Enabling engineers to account for time dependent structural characteristics at the design level.


Dynamic FEA Analysis

Dynamic FEA refers to a collection of powerful simulation techniques that can be used to model even the most complicated engineering systems.  In addition, dynamic analysis is used to assess the effects of transient loads or to plan for prospective noise and vibration issues.

As engineers seasoned in the field, a dynamic evaluation from our engineers rarely ends at the analytical output. SimuTech Group routinely collaborates with clients to provide design solutions that are both practical and profitable:

The cost of an in-field contact analysis testing is high. The use of dynamics simulations during the design stage can help to minimize or reduce the need for rig testing, as well as the operational cost of doing so.

Additionally, under dynamic loads, failure can be severe and costly. It is possible to avoid costly mistakes in the real-world application of a product by evaluating the structure during the design stage.


Advanced Linear Dynamics

For linear dynamics, the initial effort is often to determine the natural frequencies through a modal analysis.

Results are then utilized in a harmonic, shock, seismic, random vibration, or transient simulation to determine deflections, stresses, and strains. For nonlinear dynamics, a direct transient simulation can be performed.

Fluid Flow & CFD

Our collection of case studies delivers hard evidence of successful CFD consultation: dispersed particle flow, aquatic acoustic telemetry, traditional energy & bio-fuel combustion, aerodynamic drag, hydroelectric spillways, pressure wave calculation,  and broadband noise simulation, to name a few.

Ground Vibration Testing

More complicated heat transfer effects like viscous heating, compressibility, real material models, and phase change including flashing, evaporation, cavitation, and boiling are expensive to replicate in the field.  Our consultants can replicate 1:1 simulations with our state-of-the-art software and expertise.

Generator Vibration

Generators are expensive, so why ignore the risk of a full unit repair and/or extensive failure investigation?  If you hear chattering or popping during routine operations, have an expert review as soon as possible. Your Financial Director will thank you at year’s end.
