| Abstract: |
| The vibration reduction mechanism of rubber vibration absorber under random vibration excitation was studied，the calculation formula for the root mean square（referred to as RMS） acceleration response of the rubber vibration reduction systems was derived，and the influence of vibration level and compound hardness on the vibration characteristics of T-shaped rubber vibration absorber（referred to as the rubber vibration absorber） was studied.The results showed that the peak transmission rate of the rubber vibration absorber decreased with the increase of vibration level and compound hardness.The reduction efficiency of the rubber vibration absorber increased with the increase of vibration level and decreased with the increase of compound hardness.There had a significant error between the theoretical value and experimental value of the RMS acceleration response of the rubber vibration reduction system，and after linear fitting and correcting the theoretical values，the error absolute value could be controlled within ＋5%. |
