| Abstract:Based on the essential parameters of 20RK270 diesel engines and experiences from similar projects, preliminary type selection of its isolator was carried out. The displacement and velocity change of varied elastic elements under different working conditions were calculated. The calculation results showed that it was rational to choose this vibration isolation system. The follow-up vibration test verified the calculation results. |
