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.
