水下航行器试验航路设计与仿真

水下航行器的导航精度试验与航路的设计关系密切,为了找出最佳的试验航路,以得到真实可信的导航精度,该文通过对导航系统采用多普勒计程仪加光纤陀螺罗盘或惯导系统的仿真,分别计算直线航路、闭环航路和开环航路情况下的导航精度,以确定不同航路设计对导航精度的影响。仿真结果表明,由于导航系统的误差在环形航路中会互相抵消,使得环形航路试验得到的导航精度偏小,这与试验的本意相违背;而直线航路试验不受此影响,得到的导航精度较环形航路的大,是最接近真值的。本文首次提出了用仿真计算确定水下航行器试验航路的方法,可为水下航行器试验航路的选择提供依据。

Design and Simulation of Test Route for Underwater Vehicle

The navigation accuracy test of underwater vehicles is closely related to test route design.To design optimal test route and get real navigation accuracy,this paper simulates the navigation system to get its accuracy in linear route,open-annular route,and annular route tests,respectively.Simulation result shows that the navigation accuracy in annular route test is lower than the real value due to error counteraction,while the navigation accuracy in linear route test gets closer to the real value.This paper offers a new test route design method by using simulation for underwater vehicle test.
