| 摘 要： | 飞机采用固定式空中受油装置后,可能引起飞机飞行过程中的振动,严重时危及飞机的飞行安全。本文通过受油装置固有频率的计算和地面振动试验确定其频率特性,利用激波和旋涡共振理论,对受油装置的振动问题进行了分析,为某型飞机的试飞工作提供了理论支持。经过飞行试验证明分析结果是正确的,本文提出的计算分析方法对分析飞机圆形、椭圆形突出物的振动问题有借鉴意义。

| Abstract: | Vibration of fixed air refueling receptacles that can occur in flight causes serious hazards to the safety of flight.The natural frequency calculations and ground vibration tests of the refueling receptacles are conducted for the determination of their frequency characteristics.Also,the analysis of receptacle vibration is made using the shock wave and vortex resonance theories to provide theoretical supports for the flight tests of an aircraft.The flight tests have proved that the analysis results are correct.The calculation and analysis methods herein,may apply for the analysis of circular and elliptical protrusions on aircraft. |
