Studies of Noise Reduction with Designs of Tire Tread Patterns

The study uses finite element and CFD model to calculate the air pumping noise caused by process of moving tire tread, The study creates finite element model for the 205/55 R16 91V radial tire by the finite element software Abaqus, and the model refer to ISO-10844 of tire noise test regulation, replace the traditional trial and error method to save lot of development time and money, and verify the correctness of the model by the experiment. Then uses the model to explore the influence of driving conditions and structural design parameters on air pumping noise, and from analysis results, obtain delay air discharge velocity can reach the purpose of noise reduction, and design low-noise tread in the way, to save development time, the study uses a 2D Simple Model to predict result of new design, if via 2D Simple Model predictions are in favor of reduce noise, then the complete tire simulation, Finally by way of this procedure this study proposes new designs for a low noise tire by changing tread type.
