FEA examples

Automotive powertrain
The FEA consulting services group has been performing design assessments of internal combustion engines and related components for over twenty years. Our mission is to provide design guidance that is cost-effective and within the design loop.

Typical projects include:

Overall engine assessment
• Steady state and transient thermal analysis
• Stress/Fatigue (high and low-cycle)
• Gasket sealing
• Bore distortion
• Dynamic analysis
• Vibration studies

Component analysis
• Crankshaft failure investigation
• Connecting rod stress
• Exhaust manifold/EGR studies
• EGR cooler analysis
• Transaxle vibration
• Final drive gear wear study

We use multi-disciplinary CAE methods, integrating developments in CFD to improve temperature prediction and understand the importance of including non-linear effects such as:
• Coolant jacket boiling heat transfer
• Nonlinear contact
• Plasticity
• Friction
• Dynamic effects

Our automated meshing techniques and the use of PERMAS, a highly scalable FEA code, decrease the duration of the analysis cycle. This allows us to perform the typically time intensive Design of Experiment analyses required for reliability studies. Our methods have continually evolved to take advantage of the latest developments in computer and software tools.
