First, the angular velocity function and maneuver load for certain maneuver flight (including hover, dive-hike and these two combined) are set up. The simulation results of the vibration of double-disk rotor system with cantilever supported on rigid bearings show that rotor would be apparently deformed under maneuver load. Second, the performance of oil force of SFD in maneuver flight is analyzed. The results show that in maneuver flight, the SFD with centering spring will become eccentric and its oil force will be time-related and offset-related. Then, SFDs are introduced into typical Jeffcott rotor system. The whole system will be statically displaced in maneuver flight and the nonsynchronous components of oil force appear in the response of rotor system.
首先,建立了水平盘旋、俯冲拉起及盘旋+俯冲拉起复合机动三种机动飞行条件下的机动角速度函数,并确定了对应机动飞行条件下的机动附加载荷(附加离心力和附加陀螺力矩),分析了带刚支的双盘悬臂转子系统在机动飞行条件下的振动特性,发现发动机转子在机动飞行时会发生明显变形;随后,分析了非定心挤压油膜阻尼器的油膜力特性,机动飞行时,油膜轴颈在机动附加载荷的作用下偏离外环中心,使得带定心弹支的挤压油膜阻尼器也变成了非定心挤压油膜阻尼器,其非定心挤压油膜力是瞬态时变的,并且与SFD油膜轴颈偏移量和进动形态有关;然后,在经典的Jeffcott转子系统中引入带定心弹支的挤压油膜阻尼器,分析了机动飞行时非线性转子系统的振动特性,发现挤压油膜阻尼器油膜力的非协调特性也反映到转子系统的振动响应中;之后,对机动飞行条件下带挤压油膜阻尼器的双盘悬臂转子系统的振动特性进行了分析,并重点分析、总结了俯冲拉起机动飞行时,系统结构参数和工作状态参数(转速比、机动飞行半径、机动角速度等)对该系统振动特性的影响。

Because the roadbed is in the condition of stable seepage in the normal highway construction and service, the formula of level and discharge of cut, tunnel and drainage structure in condition of confined water and dive are deduced on the saturated seepage theory. The stability groundwater seepage model of highway engineering is established according to groundwater type, highway structure pattern, drain facilities pattern, whether carried on lining or timbering, combined pattern and layout.
