In this paper, on full automatic production condition, parameters of on-line sand testing system and double-disk cooler were optimized, and moulding-sand parameters of clay content, permeability, compactibility, and so on, were adjusted and optimized, and moulding-sand property parameters' control on full automatic production condition was also involved. The results can supply some reference for other similar production.

本文着重介绍了全自动生产条件下在线型砂性能检测控制仪、双盘冷却器控制参数的优化，结合生产铸件对型砂性能的实际要求，对型砂含泥量、透气性、紧实率等参数进行的调整和优化，以及全自动生产条件下砂处理工艺参数的控制范围和控制方法，本文可为相似生产条件下砂处理系统的调试和型砂性能控制提供一些参考。

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.

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。
