Project Summary

Wireless power transfer (WPT), in its general term, has been around us for decades in applications such as telemetry, satellite communications, and radio frequency identification (RFID). The WPT has recently been the focus of the industrial developments. The most common method of high power WPT is through inductive coupling that was invented by Nikola Tesla. This project based on WPT which apply eddy current for metal defect detection. Because of its resonant point attainment and frequency splitting nature due to coupling effect. Therefore, an eddy-current influence from resonance WPT is proposed in this project to quantify the cracks in a metallic sample using splitting frequency features. Two coils for transmitter and receiver are configured based on resonance inductive power transfer to act as an eddy current probe. It then scanned an Aluminum sample over three cracks area after a vector network analyzer is connected to transmitter and receiver unit. The magnitudes of the transmission coefficient for the two coils configuration measured at every scan point for the crack evaluation. Point base-features are extracted from the data, and the prinipal components analysis (PCA) also mapped its extracted feature to spatial position for comparison. The results illustrated that the magnitudes of transmission coefficient (S12) depend on geometrical nature, conductivity, and permeability of the material. Also, the depth of each crack is inversely proportional to the deviation of frequency at the crack position from that of the non-crack point. Similarly, the PCA feature shows a linear dependency between crack depth and its principal component value.

Project Objectives

Aims and Objectives of Project
? Our object for this project is to detect the flaws/faults from the metallic components. It is essential to detect and quantify cracks for safeguarding healthy structure operational services.
? Cracks initiated due to fatigue or stress loading and its propagation through the structure lead to fracture. Failure to its early detection in structures like a rail line, pipelines, and
aero plane results in a fatal accident.
? To detect the crack, eddy current testing (ECT) probes are generally used to detect the presence of cracks in conducting metallic structures.

Project Implementation Method

Methodology for Implementation of Project
Wireless power transfer approach ss applied to the probe of eddy current testing base on inductive power transfer.
? First we will review the literature from different sources. After completing literature review we start experimental setup.
? Then we start installation of hardware build up where two identical, rectangular coils for wireless power transfer approach are used to act as the sensor-probe for scanning the sample under test.
? Learn how to connect and operate the two coils to vector network analyzer (VNA -E5071B) through port1 and port 2.we try different size of layers and collect data through VNA.
? The captured VNA data signal for each scan point is transferred to the personal computer for numerical processing. Matlab numerical simulation software is used for the signal processing, feature extraction and projection via sample with crack.
? Finally, the experimental results are discussed for crack in material.
? The probe is made up of two identical wire wound rectangular coils, one for Tx excitation coil and the other one for Rx sensing coil. TX and Rx coils are configured as
series-series resonance network. For testing purposes, an Aluminum sample with 300mm length by 50mm width by 10mm depth having four different artificial surface cracks is
used. Non-crack and three crack points’ area measurements are carried out on the sample using a sweep frequency excitation ranging from almost 50 to 100 MHz at a step size of 31.25 kHz. The values of the magnitude of transmission coefficients S12 and S21 in dB are recorded and processed for feature extraction in a personal computer.
