Finite Element Analysis
Office of Automotive Engineering
Engineers routinely construct complex models and also have the engine experience to analyze the models for the most meaningful results.
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, and more.
Finite element analysis (FEA) is integral to the engine design process. Both commercial and proprietary software are used, but 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
- Valve train stiffness
- Crankshaft fatigue
- Camshaft vibratory characteristics
- Two piece piston thermal and fatigue
- Cylinder head thermal and fatigue
- Valve stresses
