摘要
研究动基座上捷联式猎雷声纳基阵的动力学特性。首先给出声纳基阵的动力学模型。考虑声纳基阵的三轴框架结构特点及猎雷艇这一动基座的存在 ,着重对声纳基阵的动力学特性进行深入的分析和研究 ,揭示出其时变、非线性、强耦合的动力学特性 ,同时指出惯量矩阵的特殊性质。计算机仿真结果表明了理论分析的正确性。分析结果对于掌握系统本质 ,设计高精度。
The dynamic characteristics of strap down minehunting sonar array on moving base are investigated.Firstly the dynamic models of sonar array are given.Considering the characteristics of three shaft frame and the presence of moving base, it gives emphasis to the analysis and research of the dynamic characteristics of sonar aray. The characteristics of time varying,nonlinear and strong coupling are posted, at the same time, the especial propertices of the inertia matrix are pointed out. Simulations show that the theoretic analysis in accurate.
