Application of an articulation index for the evaluation of a type noise

摘要

One of the importnat characteristic of the tyre is the quality of the vehicle interior noise. For an effective control of the tyre noise, it is necessary to define the relationship on the subjective rating and the objective measurement. In this study, the aticulation index method is applied to evaluate a tyre noise from objective measurements. The measurement system is built to calculate an articulation index from vehicle interior noise due to a tyre only. An articulation index rating (AI rating) is newly set up to correlate subjective feeling rate by test drivers on the test track and the articulation index measured in the Lab. The results show that AI rate and subjective rating have a good correlation. AI rating can be used for the effective control and the evaluation of the tyre noise.
