Trajectory Planning and Simulation Analysis of Automatic Ultrasonic Testing for Large Rotary Parts

Abstract

Abstract:

Based on the investigation of the existing problems in traditional manually ultrasonic testing of large rotary parts, trajectory planning and movement law of testing system were researched herein, then the motion simulation of probe inspection trajectory was carried out.This paper discussed the principles of manually testing simulated by automatic testing, set the motion law of the axles and the probe, then planned the probe inspection trajectory. All of the automatic testing process was in line with the standards of non-destructive testing and the efficiency of testing was improved 5.46 times; Based on MATLAB and ADAMS software, the probe inspection trajectory was simulated, and the planning trajectory was realized. The research and results of the simulation demonstrate the feasibility of the automatic testing take the place of manually testing, and possesses theoretical direction significance for the similar trajectory planning in future.

Key words: large rotary part, automatic ultrasonic testing, trajectory planning, motion simulation
