Rumble Strip Design Analysis to Contribute to Low Exterior Noise Using Finite Element Modeling
Optimal rumble strips/stripes are critical to ensure traffic safety and simultaneously avoid disturbance to the surrounding environment. In this project, the authors have utilized a commercial Finite Element modeling tool to calculate the amount of noise in the tires while rolling over the rumble strips. The sound level is determined within the tire cavity. The authors have evaluated three types of designs: conventional, sinusoidal, and sawtooth. In total, they have simulated 19 conventional designs, 21 sinusoidal designs, and 6 sawtooth designs at 3 varying vehicle speeds for a passenger car and a truck tire. The authors have observed that the sinusoidal designs produced lower sound outputs than the conventional designs, and the sawtooth designs with a longer wavelength produced similar sound outputs to a sinusoidal design at the same depth. Furthermore, they have developed a non-zero angle of landing for different conventional and sinusoidal designs. Overall, the numerical simulations produced expected trends in the sound outputs for different rumble strip dimensions. Furthermore, when a chosen sound output level is determined, a specific dimension can be found among the simulated cases to guide the construction.
