                      Abstract: The reinforcement ribs of the induction wheels of armored vehicles are prone to surface cracks during service
                   operation, which can pose significant risks to the safety of the vehicle during service. This paper used CIVA simulation
                   software to simulate the effect of point probe tilt on eddy current density. Based on practical application scenarios, an
                   eddy current array detection probe was designed to explore the effects of excitation frequency and lift off on eddy current
                   signals. The experiment and simulation were compared with point probes, and verified on a painted induction wheel. The
                   optimal parameters of the rectangular coil were ultimately determined, and in the actual detection process, the designed
                   eddy current array probe increased the average signal amplitude by 30% and the detection efficiency by 85% compared to
                   the point probe.
