Monte Carlo Simulations for Evaluating Engine NVH Robustness
John J. Batteh, Michael M. Tiller, Adam R. Goodman · 2005
This paper describes the use of a designoriented engine cycle simulation model in Modelica for evaluating robustness of engine NVH (Noise, Vibration, and Harshness) to noise factors. This paper highlights the novel use of the cycle simulation model for analytic robustness studies using Monte Carlo simulations. The Monte Carlo simulations allow the robustness of a statistically significant engine population to be examined upfront in the product development process. The paper also discusses a flexible, extensible tool that was developed in conjunction with the Modelica models to streamline the description, execution, and results post-processing from the simulations.
