为了达到降低钎杆噪声的目的,本文对弯曲波的特性进行实测数据分析,其次对钎杆噪声的频率特性进行了分析,总结出钎杆噪声的治理方法,并得出用阻尼材料对钎杆进行处理后可以达到5～17 dB(A)的降噪效果。
In order to reduce the noise of the drill rod, this paper analyzes the measured data of the bending wave characteristics, and then analyzes the frequency characteristics of the drill rod noise, summarizes the control method of the drill rod noise, and draws the conclusion that using the damping material to drill rod After processing to achieve 5 ~ 17 dB (A) of the noise reduction.
