Analysis

FEA

Objective

Predictive Engineering has done over 800+ FEA consulting projects in its twenty plus years in business. Our experience allows us to build FEA models quickly and correctly.  This case study presents just a few of the classic stress analyses that we have done over the last several years.  A more detailed listing can be found in this text listing Direct Text Listing of FEA LS-DYNA and CFD Projects.pdf

This short overview presents project work on:

  • High-Torque U-Joint for a Steel Mill Leveler
  • Vibration Analysis of Metal Forming Tool (Beer Can Domer)
  • Stress and Vibration Optimization of Space Frame Structure (Car Wash Frame)
  • Nonlinear Buckling Analysis of Two-Person Submarine
  • Vibration Optimization of Paper Mill Machine Component
  • Stress and Fatigue Analysis of 50 kW Wind Turbine Blade Hub, Generator Shaft and Nacelle
  • Stress and Fatigue  Analysis of Heavy-Lift Helicopter Tail Rotor Blade

Stress and fatigue analysis of a high-strength U-joint for steel mill leveling table.  The U-joint was fabricated using tool steel and high-strength steel.  FEA Consulting Services for Drive Train Components
FEA simulation of stress and normal modes vibration of a beer can domer machine.  The all hex model was built to allow quick and simple optimization of the components. Predictive Engineering FEA Consulting Services
Another type of pressure vessel is that of a submarine hull.  This hull was analyzed under the American Bureau of Shipping (ABS) Rules for Building and Classing Underwater Vehicles, Systems and Hyperbaric Facilities.  Hand calculations were done on the basic hull design followed by a finite element model of the hull.  Lifting loads and hatch cover calculations were also performed.  FEA Consultants and FEA Services

Predictive Engineering specializes in the idealization of structures and systems into numerical models.  The space frame structure above is an idealization of the steel frame of a automotive car wash system.  Loads were a combination of masses and forces to represent hanging weights and moving brushes.

Normal modes analysis using Simcenter NX Nastran of a paper mill forming board.  Optimization of the structure developed a design that was stiffer and lighter than any other structure on the marked Predictive Engineering FEA Digital Prototyping Services
A stress and fatigue investigation was done on the tail rotor blade of a Sikorsky 54B helicopter.  The objective was to extend the life certificate of the blade via a side-by-side fatigue life comparison to meet FAA requirements. FEA Consultants for Rotating Wing Aircraft
The load case was based on lift and drag calculations performed by a noted expert.  The dominate load was the centripetal force of the blade spinning at 820 RPM. FEA Aerospace Consultants
