Analysis

FEA

Objective

Our work has been tested, shaker-tabled and in-the-field benchmarked with tightly correlated outcomes on every model. Over the years, our models have consistently been within 10% of experimental measurements and our mode is typically 5%.

Numerical vibration analysis is one of the core skill sets at Predictive Engineering. Our clients have come to expect such agreement and they understand that it is due to our hard-won experience in the idealization of engineered systems into high-fidelity finite element analysis models.

Summaries are presented to show a portion of the work that we have done over the years in the fields vibratory conveyors, automotive, scientific, manufacturing and aviation. Many other examples are available for discussion but these projects provide distinctive insights into how we build and benchmark our analysis work.

Normal modes analysis videos are presented for the following projects:
Optical frame for high-speed manufacturing line
Food Processing Shaker Bed
Airborn optical turret with Kaman bearing system
Motor home frame
3,000 HP transmission for the oil and gas industry

Normal modes, frequency analysis and transient dynamic analysis were applied to the design of novel vibrating conveyor systems.
Normal modes analysis was performed on a series of driveshaft and cold-spinning motor testers.  Each model was blind benchmarked against experimental data and found to be within 4 to 8% of experimental data.
Normal modes analysis using Femap and NX Nastran for a variety of electron microscope platens and holders
normal modes and vibration analysis of high-speed manufacturing line equipment for optical scanners
Aviation hardware presents special challenges for vibration analysis due to an exacting and demanding service environment.  Normal modes and frequency sweep analysis work has been validated against shaker table work on several occasions.
Normal modes analysis using Femap and NX Nastran verified that road noise was contributing to the vibration behavior of this motor home coach frame.
Structural and modal analysis optimization of a large 3,000 HP transmission for the oil and gas industry.
