智能球铰链空间磁场分布仿真及其影响分析

摘要

Magnetic field distribution around ball head directly influences the measurement range and resolution of intelligent ball hinge. An improved intelligent ball hinge structure with several permanent magnets and magnetic effect sensors array around the spherical surface was proposed, which could be beneficial to the measuring resolution, the theory model was offered and followed by a new numerical integral algorithm. The validity of the theoretical analysis had been verified by Maxwell software simulation. After the corresponding theoretical analysis with theoretical model, the optimal spatial position matching of the permanent magnets and sensors was put forward, the result had important significance in improving the resolution.%智能球铰链中球头周边磁场分布对其测量范围和分辨率有直接的影响.该文设计一种新的结构形式,采用多个永磁体和多个磁效应传感器沿球面阵列布置的方案改善测量分辨率,给出其理论模型和新的数值积分算法.Maxwell软件的仿真结果证实理论模型的正确性,并运用理论建模完成相应的理论分析,得出永磁体和传感器的最佳空间位置匹配,对于进一步提高智能球铰链的分辨率和精度有重要意义.
