摘要
针对船体结构动态变形对系统导航精度的影响,提出一种基于变形建模的船体挠曲误差补偿方案。介绍了船体挠曲变形的处理方法,并分析了联合基座变形测量系统的工作原理,对基于变形建模的挠曲补偿方法进行深入研究并分别在载体摇摆和匀速直航运动条件下进行仿真。结果表明,文中提出的补偿方法可以相对准确的估计出载体自身的变形角,补偿后的安装误差角达到一个较高的精度。
As navigation accuracy of underwater vehicle was determined by the vehicle's flexibility distortion,the distortion error compensation scheme based on warship distortion was proposed in this paper.The treatment of vehicle's distortion was introduced and the operating principle of measurement system based on the combination basement was analyzed.The distortion compensation method based on the deformation modeling was studied and the simulations were carried out under both conditions of ship's swing and direct sailing by uniform speed.The results show that the distortion angles would be estimated with the different kinestate by the compensation scheme proposed in this paper,and the misalignment angles could achieve the higher accuracy.
