Abstract: 针对“大洋一号”和“向阳红九号”科考船中超短基线换能器轴工作状况及轴的最大转角变化无法预知的实际情况，本文提出了一种无线应变–转角测量方法。该方法主要是通过实时测量轴固定端某部位的应变，建立该应变和末端转角的数值模型，求得换能器轴的最大转角。通过实验探究换能器轴理论转角和实际转角之间的关系，实验证明：应变–转角测试方法能有效地实现最大转角的动态测量，从而为提高超短基线测量精度提供新方法。 According to the situation that the typical transducer axis “Ocean 1” or “xiangyang9” on the vessel work status or the maximum turning angle is unknown, a strain-angle testing method has been put forward.
