| Objective To improve vibration isolation performance of vibration isolation device and develop vibration isolation device with excellent low frequency vibration isolation performance. Methods The harmonic response analysis on a new combined type vibration isolation device was carried out in the 20~1600Hz frequency band with software of finite element analysis. The overall vibration isolation test was also carried out. And the vibration response of vibration isolation device under external excitation in the frequency domain was obtained. Results The result of finite element simulation and data of vibration isolation were compared. The vibration level difference was greater than 15 dB, on 20~80 Hz. On 200 Hz to 1600 Hz, the vibration level drop was also above 24 dB. RMS values of acceleration vibration level simulation and experiment were 36.6 dB and 38.9 dB respectively in 200~1000 Hz. Conclusion The combined type vibration isolation device has excellent vibration isolation performance. |
