    • An apparatus (500) for fatigue testing elongate test articles (404) including wind turbine blades through forced or resonant excitation of the base (406) of the test articles (404). The apparatus (500) includes a testing platform or foundation (402). A blade support (410) is provided for retaining or supporting a base (406) of an elongate test article (404), and the blade support (410) is pivotally mounted on the testing platform (402) with at least two degrees of freedom of motion relative to the testing platform (402). An excitation input assembly (540) is interconnected with the blade support (410) and includes first and second actuators (444, 446, 541) that act to concurrently apply forces or loads to the blade support (410). The actuator forces are cyclically applied in first and second transverse directions. The test article (404) responds to shaking of its base (406) by oscillating in two, transverse directions (505, 507).
    • 一种用于通过对测试物品(404)的基部(406)进行强制或共振激励来对包括风力涡轮机叶片的细长测试物品(404)进行疲劳测试的装置(500)。 装置(500)包括测试平台或基座(402)。 提供刀片支撑件(410)以保持或支撑细长测试物品(404)的基座(406),并且刀片支撑件(410)以至少两个自由度枢转地安装在测试平台(402)上 的运动相对于测试平台(402)。 激励输入组件(540)与刀片支撑件(410)互连并且包括用于同时向刀片支撑件(410)施加力或负载的第一和第二致动器(444,446,541)。 致动器力在第一和第二横向方向上循环施加。 测试物品(404)通过在两个横向(505,507)上振荡来响应其底座(406)的摇动。

    • An optical cavity furnace 10 having multiple optical energy sources 12 associated with an optical cavity 18 of the furnace. The multiple optical energy sources 12 may be lamps or other devices suitable for producing an appropriate level of optical energy. The optical cavity furnace 10 may also include one or more reflectors 14 and one or more walls 16 associated with the optical energy sources 12 such that the reflectors 14 and walls 16 define the optical cavity 18. The walls 16 may have any desired configuration or shape to enhance operation of the furnace as an optical cavity 18. The optical energy sources 12 may be positioned at any location with respect to the reflectors 14 and walls defining the optical cavity. The optical cavity furnace 10 may further include a semiconductor wafer transport system 22 for transporting one or more semiconductor wafers 20 through the optical cavity.
