摘要： The tuned energy redistribution system is used to precisely control the amplitude of vibrations in a vibrating system. The vibrating system typically has a resonant frequency or other vibration frequency modes that are either undesirable or of excessive amplitude. The present tuned energy redistribution system functions to redistribute the vibrational energy from these undesirable frequencies to other selected frequencies, such as by spreading the vibration frequencies out over a wide band of frequencies. The tuned energy redistribution comprises vibration input elements and/or vibration shaping elements that collectively function to enable the user to program the frequency and magnitude of the vibrations that are produced by the vibrating system. This energy redistribution is typically accomplished by providing tuned absorbers, consisting of a vibrating mass and a vibration stop, which shape the frequency response of the vibrating system by responding to frequencies mostly neartheir natural frequency of vibration and then, when the response displacement is sufficient, provide a vibration input by impacting the element in the vibrating system to which they are connected via the vibration stop, causing broad band vibration to be generated by the series of impacts.

摘要： A modular vibration system which utilizes removable modules to adapt to any of a range of applications and performance characteristics, comprising a shaker module (12), a coupling module (13) and a fixture module (14). The shaker module (12) includes features for mounting actuators (5) for providing multi-axial shaker motions to the shaker module. The fixture module (14) provides for attaching and holding specimens (6) under test. The coupling module (13) is preferably made of visco-elastic material, couples the fixture module to the shaker module, whereby the fixture module and the coupling module are easily separable from the shaker module. This feature permits tuning the vibration system over a wide range of multi-modal coupling characteristics for a specific application by allowing the interchange of fixture modules and coupling modules.

摘要翻译：调谐能量再分布系统用于精确控制振动系统中振动的振幅。振动系统通常具有谐振频率或其他振动频率模式，这是不期望的或过大幅度的。本调谐能量再分配系统用于将来自这些不期望频率的振动能量重新分配到其它选定的频率，例如通过在宽频带上传播振动频率。调谐能量再分配包括振动输入元件和/或振动成形元件，其共同起作用以使得用户能够对由振动系统产生的振动的频率和幅度进行编程。这种能量再分配通常通过提供由振动块和振动停止组成的调谐吸收器来实现，振动块和振动停止通过响应主要是天体固有振动频率的频率来形成振动系统的频率响应，然后当响应位移足够时，通过冲击通过振动停止连接的振动系统中的元件提供振动输入，引起一系列冲击产生宽带振动。

摘要： The multi-level vibration test system has controllable vibration attributes that enable the test engineer to precisely implement avibration environment that is applicable to a wide range of applications and performance characteristics. The multi-level vibration test system comprises a plurality of shaker modules that are interconnected by coupling modules and optionally includes vibration input elements and/or vibration shaping elements that collectively function to enable the user to program the frequency and magnitudes that are produced by the multi-level vibration system. This architecture as well as the numerous implementation variations that are possible using this architecture, enable the test engineer to precisely control the vibration frequencies and magnitudes that are produced.
