摘要
Abstract
The angle measurement of torsional teeth is commonly used in the manufacture and performance test of a helicopter power system.The impact of their coupling on the measurement of torsional teeth angle is examined,as is the influence of installation error caused by the non-alignment between the contact measuring probe and the direct drive motor during the measurement of torsional teeth angle,the error caused by the non-concentricity between the measuring probe and the motor during the installation of torsional teeth,and a contact measuring scheme for measuring torsional teeth angle using a magnetic encoder.A method of angle measurement using redundant observations is proposed and verified by practical angle measurement,which eliminates the influence of the installation errors of torsional teeth and probe on the measurement results,and deduces the angle calculation formula.The results show that the proposed method not only reduces the installation and debugging requirements of the measuring system but also improves the accuracy of angle measurement for the torsional teeth,making it suitable for similar precise angle measurements.关键词
