Recently, at the IEEE International Instrumentation and Measurement Technology Conference (I2MTC), professor Zhang Donglai and his doctoral students Zhou Zhihui, Zhang Enchao, Yang Yang, Zhao Min and master student Sun Jinping from Harbin Institute of Technology Shenzhen Graduate School, the School of Mechanic Engineering Automation,Power Electronics and Electrical Drives Lab have completed the paper “More accurate localized wire rope testing based on hall sensor array” together. This paper won the Andy Chi Best Paper Award of 2015 Institute of Electrical and Electronics Engineers (IEEE).
The traditional magnetostrictive guided wave testing technology chooses the single frequency pulse signal as the stimulation, which will cause the adjacent defective guided wave echo signals are easy to interlap, and then decrease the defect resolution and positioning accuracy. Concerning this issue, through studying the relations among the duration, frequency and defect resolution of drive pulse, the Group of professor Zhang Donglai advanced a magnetostrictive guided wave testing technology based on multi frequency pulse signal. This technology is a new test method based on the frequency dispersion curve of the materials need to be tested to choose the multi frequency signal, which could decrease the duration of drive pulse and increase the defect resolution and positioning accuracy. This new result has been published in “IEEE Transactions on Instrumentation and Measurement”.
The “IEEE Transactions on Instrumentation and Measurement” has considerable influence on the international instrument and measurement field. Only one paper could win the Andy Chi Best Paper Award every year which is selected from the nearly 300 published papers.
