| 中文摘要: |
| 目的 研究飞行过载状态下的橡胶减振器动态性能。方法 通过对试验件施加不同大小力来模拟过载情况，测量试验件减振前后的加速度响应。结果 对加速度响应进行分析，发现橡胶减振器主减振方向上的减振效率随飞行过载增大而减小，减振器的刚度反而增大。在正交于主减振方向上，其减振器减振效率和刚度，基本不随飞行过载环境而变化。结论 飞行过载影响橡胶减振器在过载方向上的动态性能，因此在橡胶减振器选型时，应考虑到飞行过载环境的影响。 |

| 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. |
