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.

拟议的研究计划旨在在各种微重力加载条件下对轻度次级附件和设备在大空间结构中的行为进行基本了解。一个主要目标是为敏感的机上设备制定被动和主动的振动控制策略。 将分析带有或没有振动控制装置的大型柔性空间结构和航天器上的光二级系统和设备的响应。这些系统和设备将受到声学，车载移动（旋转）仪表，升降，微米的影响以及操纵和部署负载。确定性和概率技术以及数字模拟将在这些分析中使用。将对具有被动或主动振动控制装置的二级系统调整到空间结构的性质。特别关注摩擦阻尼器的性能分析，以通过空间结构对设备的被动振动控制。
