Abstract

Vibration transmission through tires due to forces generated by the road‐tire interaction during rolling over a rough road surface is an important source of noise in the vehicle interior over a wide frequency range. Vibration transmission along the tire tread and across the sidewalls to the rim was measured by striking the tread with an impact hammer in generating transfer functions for comparison with results from an SEA model of the wheel. The effects of tire and rim resonances are noted. Transfer functions to acoustic levels in the tire cavity were also measured.
