绝对重力仪中几种隔振系统的对比测试

Comparison Experiments of Several Kinds of Vibration Isolation Systems in Absolute Gravimeter

介绍目前绝对重力仪中几种常用的隔振系统及其研究进展,并利用FG5-112绝对重力仪中的Super Spring以及现有的几种隔振系统,在相同的环境下进行对比测试。通过对测试结果的分析,给出各种隔振系统的隔振效果。该项工作的开展为下步自主研制隔振系统、提高隔振性能积累经验。

This article briefly introduces the most common vibration isolation systems in the absolute gravime- ter,comparing several kinds of mechanical vibration isolation systems with the FG5-112 absolute gravimeter under the same conditions. We evaluate the vibration isolation performance of these systems, which gives guidance in designing high performance vibration isolation systems independently in the future. Key words： absolute gravimeter; vibration isolation system; super spring
