In this experiment, the dynamic deformation of the blade at a motor speed of 40,000 rpm was measured using an ultra-high-speed imaging system and binocular digital image correlation (DIC) technology. Through quantitative analysis of key indicators including resultant displacement, point distance, out-of-plane amplitude, and Lagrangian strain, the structural integrity and aerodynamic performance of the blade under high-speed operating conditions were verified, providing measured data support for the optimization of motor power output and the validation of simulation models.
