The health state assessment and remaining useful life (RUL) estimation play very important roles in prognostics and health management (PHM), owing to their abilities to reduce the maintenance and improve the safety of machines or equipment. However, they generally suffer from this problem of lacking prior knowledge to pre-define the exact failure thresholds for a machinery operating in a dynamic environment with a high level of uncertainty. In this case, dynamic thresholds depicted by the discrete states is a very attractive way to estimate the RUL of a dynamic machinery. Currently, there are only very few works considering the dynamic thresholds, and these studies adopted different algorithms to determine the discrete states and predict the continuous states separately, which largely increases the complexity of the learning process. In this paper, we propose a novel prognostics approach for RUL estimation of aero-engines with self-joint prediction of continuous and discrete states, wherein the prediction of continuous and discrete states are conducted simultaneously and dynamically within one learning framework.

AIP Conference Proceedings 2018年第1期2028卷

作者： Tomasz Machniewicz Adam Korbel Małgorzata Skorupa Jakub Winter 1AGH University of Science and Technology Faculty of Mechanical Engineering and Robotics al. A. Mickiewicza 30 30-059 Krakow Poland

The secondary bending phenomenon, which largely affects the state of stress and fatigue life of lap joints used in aircraft structures, has been investigated analytically, numerically and experimentally. In the first case a neutral line model, originally proposed by Schijve to estimate secondary bending moments induced in mechanically fastened joints with eccentricities has been used. Numerical FEM analysis involved riveting process and then the loading of the join with consideration of non-linear material characteristics and frictional contact conditions between joint elements. The results of the above theoretical analyses were compared with each other and validated based on the experimental tests that involved the strain gauge measurements of the joint and measurements of its deformations provided by digital image correlation technique. All analyses were carried out for riveted lap joints typical for aircraft fuselage structures, consisting of 2024-T3 Alclad aluminium alloy sheets connected with MS20470-AD universal head rivets.

In this paper, a polydimethylsiloxane (PDMS) material based pneumatic actuator with a dual chambered square bellows structure was designed and simulated. Using finite element analysis (FEA), the maximum output displacement, bending angle and input pressure requirements for the actuator were analyzed. The simulation analysis revealed that 9 mm2 square bellows actuator with 17.4 mm length resulted in bidirectional bending. The actuator achieved maximum bending angles of 61° at 38 kPa and 78.5° at 45 kPa under successive and discrete actuation respectively, which makes it suitable for catheter navigation system. The results presented in this work are expected to promote the application of pneumatic based actuators in biomedical application and beyond. © Springer Nature Singapore Pte Ltd. 2017.

The overall aim of the GLIDER project is to demonstrate an innovative, flexible and cost-efficient offshore monitoring and data management approach. GLIDER consists in the deployment of 3 ocean autonomous and mobile platforms, a Sea glider (Kongsberg), a Sailbuoy (Offshore Sensing) and a Wave Glider (Maritime robotics), fitted with a well proven suite of sensors to collect chemical, physical and biological data of the ocean space. The aim is to increase the sampling of high quality marine environmental data and provide more flexible sampling schemes. These state-of-the-art platforms can move in space, provide long-term and real-time monitoring, and in addition reduce costs and CO2 emission compared to other traditional measurement approaches. A data management e-platform has been developed along with scientists and consultants to ensure a high integration of the collected data. The e-platform will allow to manage the data from storage approach, to visualization tools, and finally to allow interpretation and use for different end users. We have successfully deployed the three vehicles fitted with sensors from March to September 2018 in the Lofoten - Vesterålen area along the Norwegian coast above the Arctic circle (67°16'48''N 14°24'00''E ) with the objective to get a better understanding of the ecosystem during the spawning period of the Atlantic cod. The data collected revealed that the autonomous vehicles provide scientific information of a completely undisturbed ecosystem unlike what is collected from traditional research vessels from which instruments are deployed. The survey provided significant gain on the understanding on the dynamic and timing of biological events over large spatial and temporal scale. Furthermore, we have successfully assimilated data in real time into oceanographic model in order to improve the forecast. Currently, data are being analyzed to understand the ecosystem from the primary production to zooplankton, fish larvae, adult fish and se

Nonlinear dynamics in the einstein-Gauss-Bonnet gravity

We numerically investigated how the nonlinear dynamics depends on the dimensionality and on the higher-order curvature corrections in the form of Gauss-Bonnet (GB) terms. We especially monitored the processes of appearances of a singularity (or black hole) in two models: (i) a perturbed wormhole throat in spherically symmetric space-time, and (ii) colliding scalar pulses in plane-symmetric space-time. We used a dual-null formulation for evolving the field equations, which enables us to locate the trapping horizons directly, and also enables us to follow close to the large-curvature region due to its causal integrating scheme. We observed that the fate of a perturbed wormhole is either a black hole or an expanding throat depending on the total energy of the structure, and its threshold depends on the coupling constant of the GB terms (αGB). We also observed that a collision of large scalar pulses will produce a large-curvature region, of which the magnitude also depends on αGB. For both models, the normal corrections (αGB> 0) work for avoiding the appearance of singularity, although it is inevitable. We also found that in the critical situation for forming a black hole, the existence of the trapped region in the Einstein-GB gravity does not directly indicate the formation of a black hole.

This paper presents the new laboratory test rig of the vertical axis flexible shaft supported by two active magnetic bearings. Behind the motivation of establishing this setup is the control of vibration modes of the flexible rotor - shaft assembly, while the rotational speed varies and the unbalanced mass on the whirling disc is introduced to the system. The proposed model is aimed to simulate real operation conditions of the rotating machinery with an applied external load, with a variable structure caused by a change of material properties of the rotor - shaft assembly, or due to a fault of some elements coupled with the rotor.

Since epicyclic gearboxes are broadly employed in mining and wind turbine industry, they are frequently subjected to highly non-stationary operation conditions, with harsh changes of load and input speed. Therefore, epicyclic gearbox diagnostic methods should cover for at least three requirements: - Ability to work under rapidly changing speed and loading conditions, - Ability to work in conditions of low angular speed, - Ability to encompass and identify any faulty component of a gearbox. The most commonly used approach to epicyclic gearbox monitoring is based on acquisition of vibration signatures, due to low equipment cost and typically straightforward data acquisition procedures. Unfortunately, most of vibration signal processing and interpretation algorithms do not fulfill requirements enumerated above. This paper identifies and explains some challenges related to monitoring of epicyclic gear trains and provides concepts and solutions that are used to solve them. Capabilities and limitations of popular methods are addressed. Selected damage detection and identification methods including novelty detection approach and 2D representations of vibration signals are illustrated on the basis of data acquired on industrial gearboxes mounted on wind turbines.

The KM3NeT observatory detected the most energetic neutrino candidate ever observed, with an energy between 72 PeV and 2.6 EeV at the 90 % confidence level. The observed neutrino is likely of cosmic origin. In this article, it is investigated if the neutrino could have been produced within the Milky Way. Considering the low fluxes of the Galactic diffuse emission at these energies, the lack of a nearby potential Galactic particle accelerator in the direction of the event and the difficulty to accelerate particles to such high energies in Galactic systems, we conclude that if the event is indeed cosmic, it is most likely of extragalactic origin.

On February 13th, 2023, the KM3NeT/ARCA telescope detected a neutrino candidate with an estimated energy in the hundreds of PeVs. In this article, the observation of this ultra-high-energy neutrino is discussed in light of null observations above tens of PeV from the IceCube and Pierre Auger observatories. Performing a joint fit of all experiments under the assumption of an isotropic E−2 flux, the best-fit single-flavour flux normalisation is E2Φ1fν+ν¯ = 7.5 × 10−10 GeVcm−2s−1sr−1 in the 90% energy range of the KM3NeT event. Furthermore, the ultra-high-energy data are then fit together with the IceCube measurements at lower energies, either with a single power law or with a broken power law, allowing for the presence of a new component in the spectrum. The joint fit including non-observations by other experiments in the ultra-high-energy region shows a slight preference for a break in the PeV regime if the "High-Energy Starting Events" sample is included, and no such preference for the other two IceCube samples investigated. A stronger preference for a break appears if only the KM3NeT data is considered in the ultra-high-energy region, though the flux resulting from such a fit would be inconsistent with null observations from IceCube and Pierre Auger. In all cases, the observed tension between KM3NeT and other datasets is of the order of 2.5σ − 3σ, and increased statistics are required to resolve this apparent tension and better characterise the neutrino landscape at ultra-high energies.
