摘要
以某轿车作为测试平台,通过换装不同型号轮胎,在消声室转鼓上进行了滑行工况下的噪声测试。给出了评价轮胎噪声时轮胎附近、车内的测点位置。通过对不同型号轮胎各测点响度对比分析及同型号轮胎不同测点的频谱分析,提出了在整车消声室内测试与评价轮胎噪声的方法,为整车轮胎噪声的评价提供了试验依据。
Based on the testing platform of a c.ar, the coasting noise tests were carried out by using different tires in rotary drum of noise lab.The testing points in car and near tires were presented.The testing and evaluation method in noise lab were presented by contrastive analysis of loudness for different tires and spectrum analysis of different testing points for the same tires,the results provide a test basis for evaluation the complete vehicle tire noise.
