“…Therefore, proposing a method to analyze the mechanical properties of cables during their motion becomes crucial. However, the above research has focused on the performance of traditional cables, and with the iterative optimization of electronics, motion cables have become the primary connection method in sensors [ 16 ]. Since motion cables need to be cycled tens of thousands of times during movement, the study of their fatigue life in service is particularly important.…”

Motion cables, which are widely used in aero-engine sensors, are critical components that determine sensor stability. Because motion cables have unique motion characteristics, the study of their mechanical properties and reliability is very important. In addition, motion cables are complex in structure and cannot be applied to conventional fixed cable research methods. In this study, a new approach is proposed to introduce the theory of anisotropic composites into a simplified cable model, so that the cable is both physically conditioned and has good mechanical properties. While applying the theory of anisotropic composites, the forces of tension and torsion are considered in a motion cable under the combined action. In this context, the reliability of the structure is the fatigue life of the cable. In this paper, the mechanical properties and fatigue life of motion cables are investigated using the finite element method at different inclination angles and fixation points. The simulation results show that there is a positive correlation between the inclination angle and the extreme stress in the motion cables, and the optimal inclination angle of 0° is determined. The number of fixing points should be reduced to minimize the additional moments generated during the movement and to ensure proper movement of the cables. The optimal configuration is a 0° inclination angle and two fixing points. Subsequently, the fatigue life under these optimal conditions is analyzed. The results show that the high-stress zone corresponds to the location of the short-fatigue life, which is the middle of the motion cables. Therefore, minimizing the inclination angle and the number of fixing points of the motion cables may increase their fatigue life and thus provide recommendations for optimizing their reliability.

“…Fiber Bragg grating (FBG) is widely used in many applications, including telecommunication systems [1] and sensing purposes. In sensing applications, FBG has been used to monitor temperature [2]- [4], vibration [5], [6], pressure [7]- [9], strain [10]- [12] and acoustic [13], [14]. The vast sensing applications using FBG are due to its advantages, such as small sensor size, flexibility, non-electrical contact, immunity from electric and electromagnetic fields [15]- [17], and the ability to offer remote measurement with highperformance measurement.…”

This research investigates fiber Bragg grating (FBG) temperature sensing performance in monitoring nonâ€”uniformity of non-thermal plasma (NTP) formation in a packed-bed reactor using FBG operating at atmospheric pressure. Two FBGs made from germanium doped fiber were embedded inside and outside the PBNTP reactor to allow for comparison between the temperatures inside and outside of the reactor to be made. Each FBG comes with three grating series, which allow the reactor temperatures at three different locations inside or outside the reactor to be measured and compared. Two types of plasma, namely nitrogen (N2) and argon (Ar) were generated in the reactor at a gas flow rate in the range of 2 - 7 L/min and applied voltage in the range of l - 20 kV. It was found that the PBNTP reactor temperature varies up to 20 oC at different positions inside and up to 40 oC outside of the reactor. This finding shows the non-uniformity of plasma formation and the nature of the plasma's localized thermodynamic equilibrium (LTE). The sensitivity of the FBG temperature sensor used in this study is estimated at 10.36 - 10.50 pm/oC.
