惯导模拟台动态试验分析

Dynamic Test Analysis of the Simulation Table for Inertial Navigation

本文重点分析惯导动态模拟测试设备中主要动态参数的检测和精度问题。作者根据实际工作的体会和参阅有关资料,提出摇摆(角振动)波形失真度、相移等参数的计算方法,并在导航系统动态试验的过程中分析动态测角误差的引入,介绍一种实验法测定其误差和修正补偿的方法。

The paper emphatically analyzes the detection and accuracy of the prin- cipal dynamic parameters in dynamic simulation test equipment.The author presents the calculating method of the parameters such as the swing wave(angle vibration)distortion and the phase shift etc.According to the practical experience and referring to the relative in- formations,the author analyzes the introduction of the error of dynamic angle measurement in process of dynamic test of navigation system,and also describes an error-measuring and compensating method by experiment.
