| 英文摘要: |
| In order to solve the problem that the static moments of composite paddles are widely varied and it is
difficult to make an accurate qualification evaluation, the static moments of multiple sets of paddles are investigated by
using the control variable method according to the basic theory of the balance. By analyzing the differences caused in the
experimental data and considering the accuracy of the measuring equipment itself, the main factors that have a greater
impact on the measurement are discovered with quantitative analyses and calculations. Through comparative experiments,
it is proved that the greatest influence on axial torque measurement is the distance of the positioning surface from the
measuring cutter and its flat machining accuracy. The greatest influence on radial torque measurement is the angular
measurement accuracy of the specific section of the propeller blade. This study provides a theoretical and data basis for
process optimization for subsequent propeller design, production and maintenance, and is significant for the research and
development of new propeller blades in the future. |
