| Abstract: |
| Objective To study the dynamic performance of rubber buffer in overload flight. Method Different press was applied to test pieces to simulate overload and measure the acceleration response before and after vibration reduction of test pieces. Results The vibration reduction efficiency in the main vibration reduction direction of the rubber buffer decreased with the increase of the flight overload, while the stiffness of the damper increased instead. In orthogonal to the main vibration direction, the vibration reduction efficiency and stiffness don't change with the overload environment. Conclusion Flight overload influences the dynamic performance of the rubber butter in the overload direction; therefore, influences of the flight overload conditions should be considered in lectotype of rubber buffer. |
