	Engineers routinely construct complex models and also have the engine experience to analyze the models for the most meaningful results.

Finite element analysis (FEA), using both commercial and proprietary software, is essential to the design process.

Southwest Research Institute (SwRI)  focuses on advanced techniques to make FEA cost effective, informative, and accurate. FEA during concept design helps guide the geometry synthesis. Analysis of large assemblies is made possible by modern computer software and hardware. SwRI engineers routinely construct complex models and also have the engine experience to analyze the models for the most meaningful results.

Recent Finite Element Analysis Activities

Examples of recent FEA work include:

• Engine block stresses

  	Experience includes finite element analysis of all major engine assemblies and components: cylinder heads and blocks, pistons, connecting rods, crankshafts, valve train components, fuel system components, etc.

• Valve train stiffness

• Crankshaft fatigue

• Camshaft vibratory characteristics

• Two piece piston thermal and fatigue

• Cylinder head thermal and fatigue

• Valve stresses

• Gear tooth contact

• Connecting rod distortion and fatigue
