| 摘要: |
| 多轮系多支柱飞机刹车液压管路振动不仅影响刹车系统的工作性能及寿命,还将严重影响飞机的飞行着陆安全。在首次飞行前,必须对其刹车液压管路系统进行振动机理分析。采用压力控制系统流固耦合分析的方法,通过仿真确定振动发生机理,并将实测结果与仿真结果比较,获得多轮系多支柱飞机刹车压力控制系统谐振的关键参数。为减小刹车系统振动耦合,避免谐振现象提供便捷、可靠的解决途径和措施。 |

| Abstract: |
| The vibration hydraulic line in aircraft braking system with multi-wheels and multi-struts not only affects the work performances and life of the system but also affects the landing safety or accident prevention of aircraft landing system seriously. The mechanism of vibration should be tested and analyzed on hydraulic line before maiden flight. We carry out the analysis method based on fluid-structure coupling for aircraft braking pressure control sys-tem. We ascertain the mechanism of vibration by means of simulation and key parameters controlling resonance are acquired through the comparison of the measured results with simulation results. A convenient way and reliable measure is proposed for the sake of reducing vibration coupling and avoiding resonance phenomenon. |
