中文摘要:
      研究胎面花纹、轮胎结构和充气压力对轮胎噪声、振动和声振粗糙度(NVH)性能的影响。结果表明:优化错位排列的胎面花纹块可以减小花纹噪声;优化接头分布的轮胎结构可以提高轮胎的均匀性和NVH性能;在车速和路况相同的情况下,轮胎的充气压力越小,其噪声越小,NVH性能越好。
英文摘要:
      The effects of tread pattern,tire structure and inflation pressure on tire noise,vibration and harshness(NVH) performance were investigated.The results showed that,the tread blocks with optimizing the misaligned could reduce the pattern noise.The tire structure with optimizing the joint distribution could improve the uniformity of tire and the NVH performance.In the case of the same speed and road conditions,the smaller the inflation pressure of tire was,the smaller the noise was and the better the NVH performance was.
