As the failure of bolt connections by corrosion can result in major disasters and cause casualties and property damage, monitoring bolted joints is of great importance. However, current researches on lamb wave based bolted joint monitoring mainly focused on single-input-single-output (SISO) systems, which require a long diagnosis time and numerous transducers. To reduce the number of transducers on monitoring, the multiple-input systems, i.e. multiple-input-multiple-output (MIMO) system and multiple-input-single-output (MISO) system, can be adopted. However, both multiple-input systems are prone to failure due to the interference among the excited waves generated from multiple simultaneously-operated actuators. To remove such interference, an orthogonal variable spreading factor (OVSF) code based bolted joint monitoring method is proposed here. Firstly, instead of using the same detection signal, multiple detection signals generated using OVSF codes are emitted from different input ports. Then, for each considered input port, the corrosion information carrying waveforms are recovered from the acquired signals via timing acquisition and demodulation and utilized to reveal the status of the bolted joints via wavelet packet based analysis. To validate the proposed method, experiments with a MIMO system (i.e. three-input-two-output system) and a MISO system (i.e. six-input-single-output system) were conducted to simultaneously reveal six given bolted joint corrosion status in this research. Since the proposed method effectively suppresses the interference, the MIMO/MISO bolted joint monitoring system can present a performance similar to that of the SISO monitoring system but require fewer transducers.

The structural safety of bolted joints, one of the typical connection techniques utilized in engineering applications, is threatened by the harsh service environment. Herein, a novel damage index (DI) integrating piezoelectric impedance and ultrasonic guided wave is proposed for satisfying the damage monitoring needs of bolted joints. By integrating the two sensing techniques, the shortcomings of a single sensing technique in terms of signal interpretation, stability, and structural adaptability are eliminated. The novel damage severity factor DIZ-V is formed by fusing the damage indices DIZ and DIV weighted by multi-class DIs of the two sensing techniques. Thanks to DIZ-V and a damage mode identification factor presented in this paper, the damage modes and damage severity of early-stage bolt loosening and crack damage are identified. Furthermore, a novel dynamic superposition model (DSM) based on a dynamic-update baseline is developed to address the deficiency that the static baseline method (SBM) has. SBM utilizes the undamaged state signal as the baseline and has the problem of being prone to failure in the later-stage of monitoring. Thus, the phenomenon of nonlinear variation of DIZ-V caused by damage deterioration was avoided via DSM optimization. The feasibility and effectiveness of the proposed method were verified by conducting a series of practical damage identification tests on aluminum bolted joints. And the results demonstrated that the proposed technique could not only identify the severity and mode of damage, but also has excellent reliability. Therefore, the novel damage monitoring technique for bolted joints is a good complement to the existing techniques, which can provide a new strategy for damage monitoring.

A bolt may undergo a process from slight preload perturbation to significant preload reduction during its service life, it is a challenge to simultaneously detect both slight and significant bolt looseness based on the same waveform. Previous studies were prone to use direct wave or coda waves individually, which is suitable for a narrow range of bolt preload and cannot realize the full-range bolt preload reduction. To address this challenge, this article proposes a novel full-range bolt preload monitoring approach with multi-resolution using the time shifts of the direct wave and coda waves. Due to the difference in propagation paths, preload reduction induced time shift varies considerably between the direct wave and coda waves. By calculating the time shifts of the direct wave and coda waves, bolt looseness, including the slight preload perturbation and the significant preload reduction, can be simultaneously estimated. Based on the acoustoelastic effect and the wave path summation, a theoretical model is established, and the monitoring principles are presented. The analytical results show that the time shifts of the direct wave and coda waves are proportional to the preload variations. Validation experiments are carried out, and the results show that at specific preloading levels, the ultimate detectable resolutions of bolt preload (DRBP) using direct wave and coda waves are 1.68% and 0.32%, respectively. Therefore, the ultimate DRBP of the direct wave is 5.25 times that of the coda waves, indicating that the coda waves can be used as the “probe” with high resolution to detect tiny perturbations of preload, and the direct wave can function as a low-resolution “probe” to monitor significant preload deterioration. By calculating the time shifts of the direct wave and the coda waves, bolt looseness with different degrees can be monitored simultaneously.
