Girish Radhakrishnan

Girish leads research and development and vehicle dynamics simulation at OptimumG. He and his team are responsible for developing high-fidelity tire and vehicle dynamics models and simulations. These models are integrated in OptimumG’ s simulation software suite or may be deployed on custom software depending on client needs. Girish has been associated with OptimumG since 2018 and has been involved in numerous consulting and software projects. He has a research-based master’s from the Technical University of Eindhoven where he performed a 12-month research project under the tutelage of Prof. Igo Besselink.

Presentation

Influence of tire model complexity on high-frequency simulations

This paper presents a comparative study of different advanced tire-road contact models to simulate high-frequency curbs typically found at racetracks. The curb profile of the Singes corner at the Paul Ricard racetrack is chosen for simulations as they are known to be extremely demanding on the tires - often causing failures. An advanced four-wheel model is used to simulate an LMP2 race car at high speeds. Metrics to quantify the tire response over these high-frequency curbs are created and an investigation is conducted to quantify the influence of tire contact patch model complexity on the metrics.
