某飞行器声信标切削轨迹设计

声信标为某飞行器锥段壳体的重要设备，针对安装位置与理论位置存在较大偏差，导致切削轨迹无法精确生成，对此，本文提出集测量、编程、切削、检测为一体的切削轨迹设计方案。首先在锥段壳体设定某基准位置与声信标特征相同，然后对声信标空间位置进行测量，将锥段壳体基准位置与声信标测量位置切削轨迹通过坐标系建立联系，为此设计出声信标空间位置控制点和方向矢量计算方法；为验证切削轨迹的正确性，提出优化后处理，约束设备旋转角度，校验切削轨迹特性。最后，经试验验证，声信标空间位置控制点与方向矢量和测量数据一一对应，切削轨迹与声信标特征大小相符，该方法合理、可靠、有效。

Cutting Track Design for Acoustic Beacon of a Flying Vehicle

The acoustic beacon,which installed in the cone shell of a flying vehicle,exists big deviations between the actual installation location and theoretical installation location, leading to the cutting trajectory not be accurately generated. Therefore, a method of new trajectory design is proposed,including measuring, programming, cutting and detection. First, the actual location of the acoustic beacon is measured, and established the relationship between the spatial position and the measurement reference position through the coordinate system. And then cutting trajectory control algorithm,acoustical beacon space position control point and axial vector calculating method are designed. In this way, we verify the correctness of the cutting path, propose optimization for post-processing,constrain the rotation angle of the device and check the cutting path characteristics. At last, we make sure the acoustic beacon spatial position control point corresponds to the axial vector measurement data by test verification. The proposed method is reasonable, reliable and effective.
