Timely detection of surface damages on wind turbine blades is imperative for minimizing downtime and avoiding possible catastrophic structural failures. With recent advances in drone technology, a large number high-resolution images turbines are routinely acquired subsequently analyzed by experts to identify imminent damages. Automated analysis these inspection with the help machine learning algorithms can reduce cost. In this work, we develop deep learning-based automated damage suggestion...
Abstract This paper presents a novel framework for the structural design and analysis of wind turbine blades establishes its accuracy. The is based on beam model composed two parts—a 2D finite element‐based cross‐section tool 3D element model. able to capture effects stemming from material anisotropy inhomogeneity sections arbitrary geometry. proposed very efficient therefore ideally suited integration within aeroelastic tools. A number benchmark examples are presented comparing results...
Fundamentals of the complex approach to experimental investigations metal-working technological systems ensure parameters quality and operation properties machinery surfaces are considered. The mentioned above is applicable both at stage scientific researches under conditions experimental-technological laboratories manufacturing enterprises. It embraces matters planning, also metrological, mathematical instrumental support investigations.
Up to now many aspects of a multiuse booster stage for the next generation rockets still remain subject research and discussions. One issues is selection propellant, where amongst its criteria possibility insuring reliable chamber cooling during multiple flights. This article describes main structural elements parameters passages RD-170 family LOX/kerosene engines. Also, herein are evaluation results hardware after hot fire tests.
The paper considers possibilities of relay systems for the conveyor speed control. Computational procedures have been developed simulating control a with and without loading hopper discrete representation incoming freight flow. Estimates sampling time flow are obtained. requirements regulator simulator developed. Examples simulation using MathCAD given. average value speed, capacity rate switching taken as criteria efficiency regulation. It is shown that decreases most distinctly two-...
An approach is proposed which based on the theory of random processes and allows carrying out an objective comparative analysis results forming surface roughness profiles sliding friction joint elements both after machining during operational run-in. The research relevance determined by task a profile various technological methods, corresponds to or close one formed running-in elements, that would allow manufacturing products start operating in conditions normal wear. studies evaluate...
The article presents study results of the technological control ways for roughness operational parameters generation in tribo-elements sliding friction pairs through combined antifriction surfacing methods. possibilities parts surfaces were studied two types part cutting – based on both: application hard wear-resistant nitride-containing coatings and soft copper-containing work plates working combination with surface plastic deformation technique. Surface was carried out by diamond...
The paper deals with the issues of technological support to provide load capacity index cylindrical sliding friction joints during running-in under step stress. is one tribological characteristics, depending on design and factors. results studying tribotechnical characteristics pairs operating boundary conditions are presented. working surfaces these triboelements after preliminary finishing (turning composite 10 or grinding periphery an abrasive wheel) were subjected various methods...
For the validation of a new beam element formulation, wide set experimental data consisting deformation patterns obtained for number specially designed composite elements, have been obtained. The materials applied in beams consist glass-fiber reinforced plastic with layup configurations promoting advanced coupling behavior. Furthermore, are different cross-section shapes. from experiments also used order to improve general understanding related practical implementation mechanisms elastic...
The paper presents the results of studying parameters contact interaction between tool indenter and work surface parts while machining by methods plastic deformation diamond smoothing ball burnishing. Changes in technological factors burnishing under relatively equal conditions have different effects on formation topography microprofile. This is due to character with surface. When smoothing, rigidly fixed holder, whereas for rotates. Accordingly, sliding friction prevails rolling Friction...
