The proposed research plans to provide a fundamental understanding of the behavior of light secondary attachments and equipment in large space structures under a variety of microgravity loading conditions. One main objective is to develop passive and active vibration control strategy for sensitive on-board equipment. Responses of light secondary systems and equipment aboard large flexible space structures and spacecrafts with or without vibration control devices will be analyzed. These systems and equipment will be subjected to acoustics, on-board moving (rotating) instrumentation, lift-off, micrometeroid impacts and maneuvering and deployment loadings. Deterministic and probabilistic techniques, as well as, digital simulations will be used in these analyses. The nature of tuning of secondary systems to space structures with passive or active vibration control devices will be critically examined. Particular attention will be given to performance analyses of frictional dampers for passive vibration control of equipment aboard space structures.

拟议的研究计划提供对大型空间结构中轻型辅助附件和设备在各种微重力载荷条件下的行为的基本了解。主要目标之一是为敏感的机载设备开发被动和主动振动控制策略。 将分析带有或不带有振动控制装置的大型柔性空间结构和航天器上的轻型二次系统和设备的响应。这些系统和设备将受到声学、机载移动（旋转）仪器、升空、微流星体撞击以及机动和部署载荷的影响。这些分析将使用确定性和概率性技术以及数字模拟。将严格审查使用被动或主动振动控制装置对空间结构进行二级系统调整的性质。将特别关注用于空间结构设备被动振动控制的摩擦阻尼器的性能分析。
