Skid Dynamic and Static FEA (Finite Element Analysis)

Finite Element Analysis (FEA) can be one of the most accurate and complex analysis to perform. Compression Dynamics Consulting employs AutoDesk FEA certified engineers to achieve accurate results.

Finite Element Analysis (FEA) can be used to determine stresses, failure modes, deflection, stiffness, and many other engineering values.  Compression Dynamics Consulting has the experience to provide the appropriate constraints, models, and results to provide accurate and meaningful solutions to a myriad of common engineering hurdles.


Skid Dynamic Analysis

We use ANSYS to model the skid geometry, which can include skid structural beams and skid pedastal beams. Compressors, cylinders, vessels, and other components are typically included with the compressor manifold analysis, below.

The Skid Dynamic Analysis uses ANSYS to predict the vibration and stress levels from the compressor and driver. Inputs for this analysis include rod loads, vertical gas forces, compressor and driver imbalance, damper forces, acoustic shaking forces, and other dynamic loads on the system. This analysis is ideal for units with high horsepower or road loads.


Skid Lift (Static) Analysis

The Skid Lift Analysis uses ANSYS to predict the deflection and stress levels from the complete compressor package during lift and/or transport. Inputs for this analysis include the major component weights at their respective centers or gravity. Transportation loading can also be included. 

The deliverables of this analysis include sizing the main structural beam members in the skid and pedastals for allowable static delfection and stress levels. Deliverables also include 3D FEA on the lifting lugs, hand calculations, and spreader bar sizing. 


Compressor Manifold Analysis

We use ANSYS to model the skid geometry, which can include skid structural beams, skid pedastal beams, compressors, cylinders, vessels, and piping.

The Skid Dynamic Analysis uses ANSYS to predict the vibration and stress levels from the compressor, driver, acoustic shaking forces, and mechanical natural frequencies. Inputs for this analysis include rod loads, vertical gas forces, compressor and driver imbalance, damper forces, acoustic shaking forces, and other dynamic loads on the system. This analysis is ideal for units with high horsepower or road loads.
