“…In order to solve the abovementioned issue, the addressed fiber Bragg structures (AFBS) have been developed [27][28][29][30][31][32][33][34] and further expanded into multi-addressed fiber Bragg structures [35]. Two approaches for AFBS design have been proposed to date: 2λ-FBG and 2π-FBG.…”

“…The 2λ-FBG is based on two sequentially formed ultra-narrowband FBGs with different Bragg wavelengths [32,33]. An addressed structure with two symmetrical π-phase shifts (2π-FBG) consists of three FBGs divided by the discrete symmetrical phase shifts [27,[29][30][31]34]. 2π-FBGs are generally shorter in comparison with 2λ-FBGs, which makes them more suitable for applications where minimal sensor length is required, for instance, in load sensing bearings due to their relatively small diameter [32].…”

The work presents an approach to instrument the load sensing bearings for automotive applications for estimation of the loads acting on the wheels. The system comprises fiber-optic sensors based on addressed fiber Bragg structures (AFBS) with two symmetrical phase shifts. A mathematical model for load-deformation relation is presented, and the AFBS interrogation principle is described. The simulation includes (i) modeling of vehicle dynamics in a split-mu braking test, during which the longitudinal wheel loads are obtained, (ii) the subsequent estimation of bearing outer ring deformation using a beam model with simply supported boundary conditions, (iii) the conversion of strain into central wavelength shift of AFBS, and (iv) modeling of the beating signal at the photodetector. The simulation results show that the estimation error of the longitudinal wheel force from the strain data acquired from a single measurement point was 5.44% with root-mean-square error of 113.64 N. A prototype load sensing bearing was instrumented with a single AFBS sensor and mounted in a front right wheel hub of an experimental vehicle. The experimental setup demonstrated comparable results with the simulation during the braking test. The proposed system with load-sensing bearings is aimed at estimation of the loads acting on the wheels, which serve as input parameters for active safety systems, such as automatic braking, adaptive cruise control, or fully automated driving, in order to enhance their effectiveness and safety of the vehicle.

An Experimental Study of Surface Damage on Rolling Bearings in Low Lambda Conditions

et al. 2023

In order to better understand the occurrence of surface damage in low lambda, Λ, conditions, an experimental study was conducted. The surface damage investigations have been made based on the relationship between Λ values and surface roughness. In this study, the ball roughness, rotational speed, and oil viscosity were varied to obtain a specific Λ value which ranges from 0.10 to 0.90. It was found that three different surface damage modes, namely wear, micro-pitting, and no damage occurred depending on the ball roughness and Λ value. Morphological cross-sectional of each damage mode were observed, and surface fatigue characteristics were identified. The experimental results have shown that surface fatigue, including plastic flow thickness and crack angle, are related to contact conditions, which are influenced by surface roughness and oil film thickness.
