惯导减震器参数调整方法分析及解决方案

Analysis and solution of parameter adjustment method for inertial damper

惯性导航系统由于性能可靠、定位精度高被大量使用。主台体安装在减震器上,区别于绝大多数只有减震功能的减震器,其减震的同时还能补偿惯导系统与安装基准面之间产生转角误差,其提供的14组参数能影响姿态方向基准的传递精度。文章介绍了减震器参数的含义和测定方法,并对其进行调整,输出结果满足技术要求。

Inertial navigation system is widely used because of its reliable performance and high positioning accuracy. The main platform is installed on the shock absorber,which is different from most shock absorbers which only have the shock absorption function. It can also compensate the angle error between the inertial navigation system and the installation datum level while reducing the vibration. The 14 sets of parameters can affect the transfer accuracy of the attitude direction reference. This paper introduces the meaning and measuring method of the shock absorber parameters and adjusts them. The output results show that the parameters meet the technical requirements.
