| 摘 要： | 六自由度水声测试装置可在三维空间实现各种声呐姿态的控制,研究四自由度测控平台条件下的六自由度声学测量技术,可有效扩展四自由度声学测试平台功能,解决低自由度测控装置无法实现更高自由度声学测试等问题。通过建立维度传递模型,将四自由度测试平台条件下实测的几何量值转变为对声呐的六自由度控制,并设计了相应的声呐测试流程,计算机数值计算验证了维度传递理论及该技术方法的可行性及有效性。研究结果表明,该技术可在四自由度测试平台条件下以较高的效率实现声呐的六自由度测试。

| Abstract: | Six degree of freedom underwater acoustic testing device can control all kinds of sonar attitude in three-dimensional space.Research on six degree of freedom acoustic measurement technology under four degree of freedom measurement and control platform can effectively expand the function of four degree of freedom acoustic testing platform,and solve the problem that low degree of freedom measurement and control device could not achieve higher degree of freedom acoustic testing. By establishing the dimension transfer model,the measured geometric values under the four degree of freedom test platform are transformed into the six degree of freedom control of sonar,and the corresponding sonar test flow is designed. The feasibility and validity of the dimension transfer theory and the technical method are verified by computer numerical calculation. The research results show that the technology can achieve six degree of freedom sonar test with high efficiency under the condition of four degree of freedom test platform. |
