摘要： A preferred embodiment of a pylon has six pylon mounting links for mounting the pylon to an airframe. Each link is considered ''near-rigid'' and has a spherical-bearing rod-end on both ends such that the link can only transmit axial loads. At least one of the links has a mass carried within the link and selectively moveable by an actuating means along the axis of the link in an oscillatory manner for attenuating vibrations traveling axially through the link. The actuating means may be an electromechanical, hydraulic, pneumatic, or piezoelectric system. By mounting each link in a selected orientation relative to the other links, the actuating means may be operated in a manner that attenuates axial vibration that would otherwise be transmitted through the link and into the airframe.
摘要翻译：塔的优选实施例具有用于将吊架安装到机身上的六个安装链。每个连杆都被认为是“接近刚性”，并且在两端都有一个球形轴承杆端，使得连杆只能传递轴向载荷。链节中的至少一个具有在链节内承载的质量，并且可以通过致动装置沿着连杆的轴线以振荡方式选择性地移动，以便衰减轴向穿过连杆的振动。致动装置可以是机电，液压，气动或压电系统。通过将每个链节相对于其它连杆安装在选定的方向上，致动装置可以以衰减轴向振动的方式操作，否则轴向振动将通过连杆传递到机身中。
