六自由度装置滚转轴干扰源的诊断及其抑制

Diagnosis and Depression of the Interference Source in the Roller Mechanism of the Six-Degree of Freedom Rig

为了查找滚转轴出现定位偏差的原因 ,通过对比多种情况下滚转轴的反馈信号 ,结合相应的定位试验 ,查出了导致滚转轴出现定位偏差的干扰源。基于对滚转轴反馈信号被干扰原因的分析 ,有针对性地采取了多项措施 ,并给出了这些措施的效果。最终采用给Y轴驱动器单独供电的方式解决了这一难题 ,经风洞试验证明 。

In order to find out the cause of position deviation of the roller mechanism, the interference source is determined by comparing the feedback signals and making position test at different situations. Based on analysis of the reason that the feedback signals are interfered, several measures are adopted and their effects are given. In the end, the problem is solved by using an isolation transformer for Y axis driver. It is shown that this solution has good effects in wind tunnel test.
