摘　　要：目前美欧航天界在航天器振动环境试验中,已将采用力限制控制技术形成一项技术标准,主要目的是减少试验中造成过试验的几率,我国航天部门也开始针对此项技术进行应用研究。在力限制控制技术中如何保证力参数测量的实施和准确性是进行此项研究的关键技术之一,文中主要介绍在此项研究中多分量力参数测量的实施过程,及测量的数据结果和数据分析,目的是对振动试验环境使用测力单元进行力参数测量技术进行一次总结,为进一步开展力参数测量技术的研究积累经验。At present, the force limited control technology has become a standard on spacecraft dynamic environment test at NASA and ESA. Rs main purpose is to reduce the probability of over test. Our aerospace departments also perform studies on this field. That how to guarantee the measurement of force parameters in force limited vibration test is a part of key technique. This paper introduces the measurement process of the multi-axis force parameters. Also, the measurement result and data analysis are presented. This paper is to summarize the technology of force parameters measurement using the FMD and acquire the experience for developing the study on measurement the force parameters.
