摘要
分析了摆式列车过曲线时的圆锥运动效应及其对角速率陀螺仪测量结果的影响,提出了圆锥误差补偿的"多子样"算法。仿真计算表明,采用该补偿算法能有效地提高摆式列车姿态解算精度,对于保证摆式列车正确倾摆具有重要意义。
The coning motion effect and its affection on measurement results of the angular velocity gyroscope are analyzed in this paper. Corresponding coning motion compensation algorithm called the multi-sample method is put forward. Simulation shows that this compensation algorithm can effectively increase the attitude computation accuracy of tilting trains, this is of importance to ensuring correct tilting while tilting trains run through curves.
