摘　　要：从实际工作角度出发,对前雨刮器的车内振动噪声问题进行了实验研究。通过声振试验测试了雨刮器高低速档的车内噪声和高速档主要零部件的振动状况,应用频域分析技术对振动和噪声数据进行研究和分析,识别了主要噪声源,在此基础上对噪声的传递路径作了分析,利用脉冲激励试验获得的数据,对雨刮器车内噪声的影响因素进行了深入地分析,提供了合理的降噪建议。An experimental study of the actual interior noise of a front wiper is described.Through a vibro-acoustic experiment the interior noise in high speed and low speed of the wiper and its components＇ vibration levels in high speed are measured.Frequency-domain analysis technique is applied to investigating the data of noise and vibration.The main noise source is identified.Based on the noise source identification,noise transfer path is discussed.Through the data of impulse excitation,it is found that the wiper has an effect on the interior noise.Finally,suggestions for noise reduction is presented.
