摘　　要：为确保基于室内转鼓法所得单条轮胎噪声转换至整车轮胎噪声时结果准确合理,采用室内转鼓法和惯性滑行法对不同类型轮胎进行噪声测试,并对相同工况下不同的转鼓室和室外实验场的测试结果进行分析处理。结果表明:通过在转鼓室内布置声阵列对单条轮胎进行噪声测试,并结合文中确定的最优转换系数,最终预测的整车轮胎噪声准确可信。最终确定通过单条轮胎预测整车轮胎噪声的转换系数,这对轮胎的开发与研究具有重要意义。In order to ensure the accuracy and reasonability of the results when converting the single tire noise to the entire vehicle tires noise with indoor drum method,the noise test for different types of tires is conducted by using indoor drum method and coast-by method respectively.The test results of different indoor and outdoor tests under the same working condition are processed and analyzed.By testing the noise of a single tire with acoustic array in the drum laboratory and according to the determined optimal conversion coefficient,the accurate and reliable noise of the tires of the entire vehicle is predicted.This work is of great significance for research and development of tires.
