Abstract
<div class="section abstract"><div class="htmlview paragraph">There are two key factors driving the tyre manufacturers to increase their focus on improving the noise characteristics of the tyre: Strict homologation requirements for tyre and vehicle noise and the increasing prevalence of Electric vehicles. With developing infrastructure and vehicle technology, the tyre noise impact on overall vehicle noise is becoming more and more important. The principal focus of the study is to perform experimental analysis for understanding the effect of various operational parameters such as load, inflation pressure (IP) and speed on overall tyre noise in a semi-anechoic chamber under controlled conditions. To understand the impact of the operational parameters, five C1 class radial tyres with different rim sizes (14”-18”) and same tread patterns were used. The study includes measuring the overall tyre noise expressed as Sound pressure level (SPL) in dB(A) using microphones at three different locations inside the semi-anechoic chamber on a 2m steel drum i.e., Leading edge Mic (LM), Trailing edge Mic (TM), and Center Mic (CM). These three microphone locations will help us to recognize the impact of the operational parameters on aerodynamic, vibrational and amplification or reduction noise generating mechanisms. A test matrix with varying load (50%-125%), speed (40km/h-100km/h) and inflation pressure (200-260kPa) were used to capture the overall noise characteristics.</div></div>
