为了实现大型导弹制导鉴定、改进和可靠性测试与分析，希尔空军基地生存性与脆弱性集成中心（SVIC）安装了一个六自由度冲击和振动系统。由怀尔实验室公司设计和开发，该系统在5至2000 Hz的频率范围内由八个电动振动器驱动，每个水平轴上有两个振动器，垂直轴上有四个振动器。主要的设计关注点是振动筛通过刚性工作台的耦合，这是由于动力学和动力学效应以及结构的行为。这使得控制任务非常具有挑战性。开发了一种协调驱动信号以补偿交叉耦合效应的方法。根据迄今为止的测试，该系统是一个有效、可靠和有能力的测试平台。在本文中，我们讨论了设计目标，提供了一个简单的硬件描述，并详细说明了高速，数字控制系统驱动的八个电动…
To achieve large-missile guidance qualification, modification, and reliability tests and analysis, the Hill Air Force Base Survivability & Vulnerability Integration Center (SVIC) has installed a six-degree-of-freedom shock and vibration system. Designed and developed by Wyle Laboratories Inc., this system in driven in the frequency range of 5 to 2000 Hz by eight electrodynamics shakers, two in each horizontal axis and four in the vertical axis. The major design concern is the coupling of the shakers through a rigid table due to kinetic and dynamic effects and the behavior of the structure. This has made the control task very challenging. A method was developed that coordinates the drive signals to compensate for cross-coupling effects. Based upon tests to date, the system is an effective, reliable, and capable test platform. In this paper, we discuss the design objectives, provide a brief description of the hardware, and elaborate on the high-speed, digital control system driving the eight electrodynamics...
