摘　　要：自然风场对外场停放的航空器有直接影响,可能引发振动、位移甚至倾覆。以波音737-300型飞机为例,对中长期在外场停放的航空器进行数学建模,分析了机翼振动特性和机身振动模型,提出航空器与当地最大频率风向呈夹角71°~78°时,可有效降低风致振动效应。通过不同停放方向的实践和两个周期的数据检测,证实数学模型有效。当遇强风,在前货舱放置航空器重量2.23%的压舱物,则可以很好地抑制机身上下振动,并提出一种用于非适航航空器的系留方式,经过台风天的检验,具备实用价值。Natural wind fields have a direct impact on aircraft parked outside,which may cause vibration,dis⁃placement,and even overturning.Taking the Boeing 737-300 aircraft as an example,mathematical modeling was conducted on aircraft parked in the field for a long period of time.The wing vibration characteristics and fuselage vibration models were analyzed,and it was proposed that when the aircraft forms an angle of 71°~78°with the local maximum frequency wind direction,wind-induced vibration effects can be effectively reduced.Through practice in different parking directions and two cycles of data detection,it has been confirmed that the mathematical model is effective.When encountering strong winds,placing a ballast of 2.23%of the aircraft’s weight in the front cargo hold can effectively suppress the up and down vibration of the fuselage,and a mooring method for non-airworthy air⁃craft is proposed.After testing on typhoon weather,it has practical value.
