    • Improved force generator (FG) devices and methods are provided herein. A FG device (10) includes a housing (16, 18), a shaft (S) centrally disposed within the housing, and multiple imbalance rotors (30, 32, 34, 36, 38) disposed within the housing and provided along the shaft. At least two pairs (PA, PB) of imbalance rotors are provided in a nested configuration with respect to each other along the shaft. The at least two pairs (PA, PB) of imbalance rotors are supported in the nested configuration by large and small bearings (BA, BB). Any two imbalance rotors are paired to rotate together in a same direction according to a desired vibration canceling force. A method of controlling vibration within a structure is provided. The method includes detecting vibration, receiving a force command at a FG device, and pairing any two imbalance masses together and rotating a pair of imbalance masses via the rotors together in a same direction to cancel the detected vibration.
    • 本文提供了改进的力发生器(FG)装置和方法。 FG装置(10)包括壳体(16,18),中心地设置在壳体内的轴(S)以及设置在壳体内并沿轴设置的多个不平衡转子(30,32,34,36,38) 。 至少两对(PA,PB)的不平衡转子相对于彼此沿轴设置成嵌套构造。 不平衡转子的至少两对(PA,PB)通过大型和小型轴承(BA,BB)在嵌套构造中支撑。 根据期望的振动消除力,任何两个不平衡转子成对地沿同一方向一起旋转。 提供一种控制结构内的振动的方法。 该方法包括检测振动,在FG装置处接收力指令,并将任何两个不平衡质量块配对在一起,并将一对不平衡质量块通过转子沿同一方向一起旋转,以消除检测到的振动。

    • Improved vibration damping devices (10), systems, and related methods are provided herein. In some aspects, damping devices and related methods can be used in single rotor or tandem rotor aircraft. In some aspects, a vibration damping device (10) for use in a vibration damping system of an aircraft can include a housing (10), at least two imbalance masses (42b, 44b) provided in a side-by-side configuration within the housing, and at least two more imbalance masses (40b, 46b) provided in a nested configuration within the housing. In some aspects, devices, systems, and methods include rotating any two imbalance masses provided within the housing in a same direction. Such rotation can result in a linear force for counteracting vibration occurring within the aircraft. In some aspects, devices described herein can include one or more processors for executing commands from a controller within a damping system.
    • 本文提供了改进的减振装置(10),系统和相关方法。 在一些方面,阻尼装置和相关方法可用于单转子或串联转子飞机。 在一些方面,用于飞机的减振系统的减震装置(10)可以包括壳体(10),至少两个不平衡质量块(42b,44b),其设置在 壳体,以及设置在壳体内的嵌套构造中的至少两个不平衡质量块(40b,46b)。 在一些方面,装置,系统和方法包括以相同的方向旋转设置在壳体内的任何两个不平衡块。 这种旋转可以产生用于抵消在飞行器内发生的振动的线性力。 在一些方面,本文描述的装置可以包括用于在阻尼系统内执行来自控制器的命令的一个或多个处理器。
