Research progress of automated ultrasonic imaging detection technology for complex aircraft components

CHEN Yao, XIONG Zhenghui, LUO Junwei, WANG Hanyang et al. • Journal of Aeronautical Materials (2025)

Traditional ultrasonic automated non-destructive testing is a great challenge in the inspection of aviation components with complex surfaces. Complex surfaces can interfere with the formation of the focus in the sound beam,and the waveform ...

Parameter Fuzzy Self-Adaptive Dynamic Window Approach for Local Path Planning of Wheeled Robot

Lidan Xiang, Ximin Li, Hao Liu, Peng Li • IEEE Open Journal of Intelligent Transportation Systems (2022)

As a classic algorithm for realizing robot local path planning, the dynamic window approach (DWA) uses an objective function to choose the optimal velocity commands. However, the path generated by the DWA in the complex environment is not s...
