摘　　要：介绍模拟器分离试验台和子体释放机构。在子体与母体分离试验中出现振荡现象。通过建立模型,对振荡源进行理论分析;结合大量试验,总结振荡源的产生原因和影响因素,并提出改进措施。分析振荡源,可更准确地洲出在分离过程中,子、母体的姿态和速度,为真实太空环境下筒式偏心在轨分离提供数据依据。A simulator separation test-table and a daughter release mechanism were introduced. An oscillation phenomenon appeared in the daughter and maternal body separation tests. The oscillation source was analyzed in theory by building a model. Combined with a large number of tests, the reasons for oscillation source＇s appearing and influencing factors were summarized and the improving measures. Through analyzing oscillation source, the attitude and speed of the daughter and the maternal body were presented could be measured more accurately in a separation process. The study results provided a data basis for tubular type offsets on orbit separation under real spaee environment.
