Abstract
A finite element modeling technique is employed in this paper to predict the force transmissibility of tire-cavity-wheel assembly under a free-fixed condition. The tire and wheel force transmissibility is factor in structure borne road noise performance. In order to improve structure borne noise, it is required to lower the 1st peak frequency of force transmissibility. This paper presents an application of finite element analysis modeling along with experimental verification to predict the force transmissibility of tire and wheel assembly. The results of finite element analysis for force transmissibility are shown to be in good agreement with the results from the indoor test. In order to improve structure borne noise, it is required to lower the 1st peak frequency of force transmissibility. And, the effect of the tire design parameters such as the density and modulus of a rubber and the cord stiffness on the force transmissibility is discussed. It is found that the prediction of the force transmissibility model using finite element analysis will be useful for the improvement of the road noise performance of passenger car tire.

Summary
Noise generated by rolling vehicle tires is a topic of significant and growing concern. In general the tire and wheel force transmissibility is factor in structure borne road noise performance. Lage et al [12] studied a relationship to obtain the force transmissibility from the displacement transmissibility and vice versa, in multiple-degree-of-freedom systems This relationship will allow one to perform force identification using displacement transmissibility, which is a very practical technique, especially if the displacement transmissibility can be measured in operational conditions, not using frequency response functions. Understanding of the tire force transmission mechanism from the wheel hub center to tire tread due to road disturbances uses the modal dynamics using finite element analysis. This paper proceeded with the finite element method to understand how to force transfer the wheel hub center to tire tread. The DOE using finite element method is conducted to lower the 1st peak frequency of the force transmissibility
