With a spring installed inside table, you can move it up and down, and it can adjust the pressure, swing it before and after by eccentric wheel and pulley. The swing margin is about 12 degrees. The platform was installed in the L-plate and can correct center to ensure die non-deformation and roundness in polishing process.

工作台里面安装弹簧一根，可以上下移动，并可任意调整压力，利用皮带轮和偏心轮带动，使前后摆动，摆动幅度约12度，而工作台被安装在 L 型拖板上可以任意地对中心，确保在抛光的过程中，使模具不变形及圆度。

In this paper, the adjustment parameters of universal rolling disk in gear grinding machine, such as generating length, eccentric distance of generating and differential crank disk are calculated.

The Metal seated butterfly valve adopts a double eccentric structure and a inclined cone seal. The seal-ring can be separated once open the disk, and the valve can be sealed once the seal-ring contacts the disk. This structure can decrease the friction torque when the butterfly valve opens and closes, and expanded the life time, and make opening and closing easily.

斜锥面金属密封蝶阀设计采用了一个双偏心和一个特殊斜锥椭圆密封结构，实现蝶板在开启瞬间密封面即分离，关闭接触即密封的效果，这种密封结构实现启闭无机械滑动摩擦，大大延长了密封件的使用寿命，并且达到启闭轻松自如目的，且具有密封自动补偿功能。

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。

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.
