一、引言宇宙空间站环境中的平均重力级为10~(-6)g,而点火发射火箭或推动宇航员起程的暂时干扰对振动敏感的试验冲击大约为3.0×10~(-4)g.处于试验位置附近的泵,可在10赫下发生0.4g 的稳态振动.所以就改变了微小重力环境,因而降低了试验的有效度.本课题的目的就是为减小从宇宙空间站结构到振动敏感的有效载荷所传递的振动而寻找一种设计和测量(评价)方法.所采用的技术和方法也适用于试验室中低重力环境 I. INTRODUCTION The average gravitational level in a space station environment is 10 ~ (-6) g, while the vibration-sensitive test impact of a rocket firing or a temporary disturbance of astronaut departure is about 3.0 × 10 ~ (-4) g. In the vicinity of the test site, a steady-state vibration of 0.4g can occur at 10 Hz, thus changing the micro-gravity environment, thus reducing the validity of the experiment.The purpose of this project is to reduce the vibration from the space station structure to the vibration Sensitive payload to find a way to design and measure (evaluate) the vibrations transmitted. The techniques and methods used are also suitable for use in low-gravity environments in laboratories
