Award For Creativity in Engineering

这项拟议的研究计划提供对大型空间结构中轻型次级附件和设备在各种微重力加载条件下的行为的基本了解。其中一个主要目标是为敏感的车载设备开发被动和主动的振动控制策略。将分析大型柔性空间结构和航天器上安装或不安装振动控制装置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、微米撞击以及机动和部署负载的影响。在这些分析中将使用确定性和概率技术以及数字模拟。二次系统调谐到具有被动或主动振动控制装置的空间结构的本质将被严格地检验。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。

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.
