摘　　要：针对某车型在中高速行驶过程中出现的嗡嗡异响问题,通过加速和匀速工况的振动和噪声测试分析,识别车内异常噪声产生的原因为车轮径向16阶振动。结合轮胎不同状态下的空腔模态分析和轮胎均匀性检测,确认问题原因是轮胎RFV(Radial force variation)H16偏大,在高速时与轮胎空腔共振导致轮胎径向16阶振动偏大,从而引起异常轮胎噪声。通过对轮胎的生产制造工艺分析,提出了生产优化和质量监控的方法,改善后的轮胎在高速下的RFV H16明显降低,实车道路验证了控制方法的有效性,可为后续排查此类问题提供参考。Identification of the buzzing noise of a vehicle operating at high-speed is studied.Vibration and noise test is done under the driving modes of acceleration and constant speed.The results confirm that the 16th order vibration of the wheel is the main influencing factor.According to the tire cavity modal analysis under different states and the tire uniformity detection,the 16th order radial force vibration(RFV)of the tire is further confirmed to be the major cause of the buzzing noise,which resonates with the tire cavity at high speed and then leads to the buzzing noise.Through the analysis of tire manufacturing process,the method of production optimization and quality monitoring is proposed.The 16th order RFV of the tire at high speed after the improvement is significantly reduced.The effectiveness of the control method is verified by road test.This work provides a reference for the identification of buzzing noise of vehicles.
