A new type of damper fastener is tested by using the hammer excitation method,and the damping performance is analyzed from four aspects(transmission rate; transmission loss rate;transmission loss and Z vibration level).The results show that in the range of 4~200 Hz,the transmission rate is mainly below 2.5%;the transmission loss rate is mainly above 97.5%;the transmission loss is mainly above 32 dB;and after calculating the track vertical vibration acceleration,Z vibration level is 86.15 dB;compared with the ordinary damper fastener,the vibration attenuation performance of the new type damper fastener has been significantly improved.The test shows that the hammer excitation method is effective,convenient operation,which is an excellent test method for the vibration attenuation performance of damper fasteners.
