A Thin Blade Error Analysis Strategy Based on Model Matching

Abstract:

Aiming at error evaluation of aero-engine blade airfoil in blade inspection. A new inspection method based on modeling matching is proposed, through the introduction of location weighting factor the mathematical model is built to accomplish precise matching between the CAD design model and measurement model. Besides, gradient descent particle swarm optimization (PSO) method is used to optimize the calculating process. Besides, thin blade error evaluation system is developed based on UG/OPEN API technology. Practical example proved that the present method can improve the accuracy of the error evaluation, and reduce the misjudgment of the thin blade.
