In this project, we 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. We have evaluated three types of designs: conventional, sinusoidal, and sawtooth. In total, we 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. We 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, we have developed a non-zero angle of landing for different conventional and sinusoidal designs. Overall, our 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.Noteby Jinta Zheng, Yue Zhang for Oregon Department of Transportation Research Section and Federal Highway Administration.Title from PDF title page (viewed on August 23, 2022)."FHWA-OR-RD-23-01"--Technical report documentation page."PROJECT SPR 829."This archived document is maintained by the State Library of Oregon as part of the Oregon Documents Depository Program.
