“…The study also showed that vibrations on the vehicle body were absorbed during the operation of the VSS compared to the lower arm that did not rely on the VSS, which gave a high-frequency value. The main factor affecting the driving comfort of a vehicle is the vibration caused by the unevenness of the road acting on the wheels and through the VSS transmitted to the vehicle's body [20]. The stiffness and damping of the VSS affect the vibration strength and comfort of the car.…”

The use of piezoelectric sensors in the data acquisition of vibration signal for monitoring systems on vehicles is a practical way to determine the performance of vehicle suspension systems (VSS). However, the transmission of vibration signal data through piezoelectric sensors still relies on conventional techniques, such as wires, which can cause problems in areas with limited space and pose a safety risk for moving vehicles. This study developed a wireless piezofilm sensor-based data acquisition device to monitor VSS using an Arduino microcontroller as a signal processor and a Bluetooth HC-05 module as a wireless communication link with a control terminal. The data acquisition process is carried out by measuring the electrical signal resulting from the vibration of the piezofilm sensor caused by the dynamic motion of the VSS operation. The signal data acquired from the car's body and lower arm was analyzed using the Fast Fourier Transform (FFT) analytical method for comparison. The results of the analysis show that the vibration increases with the increase of the car speed. It found that the vibration at the lower arm of the car is higher than the body part. It can conclude that the developed wireless piezofilm device is effective and capable of performing VSS monitoring.

“…The latter is not thicker than the films/wires and smooths out the roughness. Trial applications of piezo films into composite blades [ 19 , 26 , 27 ] demonstrated workability of such technical solutions in operational conditions. For instance, the measurement system remained functional at rotating frequencies up to 25 rev/sec, with no discernible effect on the aerodynamic profile.…”

Health monitoring of critical structures, that form parts of serial operating objects, is a pressing task. The Operational Modal Analysis (OMA) techniques could be the optimal solution. An inexpensive measurement system, such as the OMA, uses a lot of sensors for structural response assessment. The health monitoring of serial structures has to also consider possible deviations between samples. A solution providing the OMA application includes the compact measurement system based on piezoelectric film sensors and modal passport (MP) techniques. For validation of the proposed approach, a series of five similar composite cylinders, with a network of piezoelectric film sensors, was used. Applying modal tests on the specimens, and using OMA with MP methods, the set of typical modal parameters was determined and analyzed. The results of the study confirmed the feasibility of the sensor network and its applicability for structural health monitoring of serial samples using OMA methods. The proven effectiveness of OMA/MP techniques, combined with a sensor network, provides a prototype of intelligent sensor technology, which can be used for health monitoring of structures, including those that are part of an operating facility.

“…On the other hand, piezofilm sensors measure deformations in the longitudinal direction (compression/stretching), which is beneficial in many cases. The films are also light and can be glued tightly on the surface or embedded inside composite structures [39]. Furthermore, if only the dynamic component of deformations has to be measured, advanced piezofilms, which do not require balancing circuits like, for example, Wheatstone bridges for resistive strain gages can be employed [39].…”

“…It was found that the measurement system was sensitive to several disturbances, including acoustic excitations. In [39] and [50], PVDF film sensors were attached to a surface of a glass-fiber polymer composite helicopter blade. It was possible to perform the OMA and to identify modal parameters during rotation of the blade at nominal rotational speeds, which was not possible with the EMA in the static mode.…”

Statistical Structural Integrity Control of Composite Structures Based on an Automatic Operational Modal Analysis — a Review

2022

View full text Add to dashboard Cite

The operational modal analysis (OMA), as a passive technique, has found a practical application in the structural health monitoring (SHM) of structures in service subjected to dynamic loadings. The state of structural integrity is judged by exploring the changes in values of the modal parameters estimated by the OMA. However, the entire framework of on-line damage identification and continuous monitoring is rather complex, involving several key building blocks. This work reviews the main steps in achieving the functionality of automatic damage identification in composite structures with a particular focus on wind turbine blades. The sensor instrumentation, extraction of damage-sensitive features from measured response signals, removal of environmental influence, automatic classification of physical and spurious modes of the system, and application of a statistical control to obtain the information on the possible structural damage are discussed. The merits and limitations of the OMA-based SHM approach for composite wind turbine blades are indicated.
