The alternating current field measurement (ACFM) technique has been widely used in the defect detection of metal structures. However, identification and reconstruction defects depend on human experience or simple empirical formulas, which leads to misjudgment large quantization errors. In this article, we propose an end-to-end physics-informed neural network for 3-D reconstruction. high-precision automatic system with a specially designed probe is established detect any direction. faster...
Alternating current field measurement (ACFM) technique has been widely used in defect inspection of underwater metal structures. However, due to the high cost inspection, it is difficult carry out nondestructive testing (NDT) regularly obtain health status key nodes And quantification defects depends on simple empirical formula, which leads large quantization error. In this paper, a flexible ACFM magnetic sensor array for in-situ structural cracks proposed. A probe based manufactured and can...
Aircraft structures are prone to fatigue cracks under various loads, which seriously threaten the safety performance of aircraft. Therefore, it is particularly important carry out long-term structural health monitoring (SHM) for key nodes aircraft structures. This article attempts apply alternating current field measurement (ACFM) technique SHM field. In this article, based on principle ACFM, a uniform (UACFM) proposed. Through simulation analysis, change law corresponding characteristic...
As an important connection method between drill pipes, the thread is prone to fatigue cracks and stress corrosion due long-term exposure complex forces corrosive environments. The crack detection system of pipe based on altering current field measurement (ACFM) proposed. model using ACFM developed by finite element software COMSOL. distribution induced magnetic above extracted. relationships characteristic signal depth angle are analyzed. probes established, different types two...
Abstract Nonferromagnetic pipes are widely used in power plants such as fluid transportation and heat exchanger devices. Due to the severity of environments, including corrosion, high temperature, etc, they subject surface arbitrary-angle cracks. In view this background, paper proposed a rotating alternating current field measurement (RACFM) testing system for cracks on nonferromagnetic pipes. The RACFM pipe detection model is established unidirectional excitation coil orthogonal coils...
