Sumitomo Rubber's advanced simulation technologies for tire aerodynamics and noise

As the transition to electric vehicles (EVs) progresses, the absence of traditional engines increases the impact of tire-induced air resistance and noise. To address this, Sumitomo has developed simulations to predict the aerodynamic and noise properties of tires. For aerodynamics, the company has created a simulation that considers the tire patterns and rolling states to reduce drag. For noise, it has developed a method that combines tire and vehicle vibrations to predict and improve noise performance. These advanced simulation techniques support the spread of electric vehicles and their model-based development (MBD).
