SwRI: Automotive Systems Contamination Research Modeling and Simulation

	After changing fundamental models of deterministic systems to stochastic models, SwRI scientists simulate the influence of contaminants in a system.

During component and system development, performance predictions are often based on specific physical characteristics and deterministic operating parameters. System contaminants often modify operating performance, resulting in a change of deterministic equations to stochastic models involving time-varying, probabilistic random variables.

 
Using contamination sensitivity analysis, testing, modeling, and simulation methodologies, Southwest Research Institute (SwRI) engineers help manufacturers:

• Design components to function:

  • At given contamination levels

  • For suitable periods of time

  • With acceptable performance

• Identify contaminant-sensitive components

• Develop realistic service-life estimates

• Achieve targeted service life for final designs
