Abstract

Tire-induced noise and vibration spans a wide range of frequencies, depending on, among other attributes, tread design, road surface, and vehicle speed. Vehicle designers are faced with the daunting task of minimizing this broad frequency of energy. The design of suspension systems must take into account the need to have a well-tuned frequency response.

In this paper, a new approach toward minimizing tire-induced noise and vibration is presented. The methodology is based upon a new perspective of employing antiresonance, as opposed to damping phenomena, to effectively tune systems for practical performance. The mechanical structure of the system is amenable to cost-effective manufacture and can be packaged in different configurations. We present the fundamental approach toward the design and give several example configurations.
