Research on tire quality evaluation method for lateral force coefficient test

Abstract This paper conducts research on the quality evaluation method of tires used in lateral force coefficient testing. By applying the analytic hierarchy process (AHP), a comprehensive tire quality evaluation system was established, taking into account the chemical properties, physical and mechanical properties, and measurement uniformity of the tires. This system breaks the limitation of traditional single-factor evaluation and accurately reflects the quality of the tested tires. The AHP method shows good adaptability in the evaluation, determining the reasonable weight of each evaluation factor for the tested tires produced by different manufacturers in the lateral force coefficient testing scenario, such as the factors related to lateral force in physical and mechanical properties, the chemical composition of anti-wear chemical substances and measurement uniformity, which have a key impact on the test results. In addition, it achieves an organic combination of quantitative and qualitative factors by rationally quantifying qualitative factors and combining them with quantitative data, making the evaluation results more scientific and convincing, and effectively avoiding evaluation biases. It provides a reliable basis for the selection and quality control of tested tires.
