Published: February 2021

Abstract
With the development of power grid, the amount of data and calculation generated by network edge devices is increasing rapidly, which brings the pressure of data analysis and storage, service interoperability and model expansion. Traditional edge cloud collaboration mode uses user-defined model manually, and then downloads the model from the cloud to the edge for execution to expand the model. This method relies heavily on human experience and is difficult to ensure the efficiency of model expansion when the amount of data is large. Based on the analysis of three basic capabilities of service interoperability system, this paper innovatively proposes an automatic construction method of service extension. Firstly, the model is described as a tree structure, and then the model is automatically added from the edge to the cloud as a branch. Finally, a complete industry interoperability model library is formed in the cloud.

Published: February 2021

Abstract
Virtual reality (VR) technology makes it possible to interact directly with virtual space. Virtual reality enables everyone to draw three-dimensional graphics in this intuitive way. So we study vr virtual reality technology and painting. We use photo sprayer, a virtual painting tool, to create digital art in virtual reality (VR). Users can capture images of local landscapes, objects, faces or random details and convert them into colors and patterns of digital artworks on 2D surfaces and 3D objects. Previous studies have shown that both the rendering of 3D objects and the use of virtual reality can improve the skills of mental rotation and spatial visualization. Since virtual reality drawing is a combination of non memory activities, it seems to be a promising ability to study its influence on these spaces. This paper studies the educational application of virtual reality painting and its relationship with spatial ability.

Aspects regarding the increase of the protection level of the falling-object protective structures (FOPS) by using the post-critical behavior of the support elements
Authors: Dumitrache P , Goanță A M 
Published: February 2021

Abstract
For earth-moving machinery which are operated in areas with danger of falling objects on its cabin, an important performance requirements imposed on the machine is the protection of the human operator in case the cabin is hit by a falling object. As a result, the mechanical system formed by the cab’s strength structure and its supporting elements must have the ability to dissipate high impact energies, so that the deformed system does not penetrate the deflection limiting volume (DLV). In general, the support on the chassis of the falling-object protective structures is rigid, so almost all impact energy is dissipated in the deformation of the cabin’s strength structure. The present article proposes that most of the impact energy be dissipated in the post-critical deformation of some dissipative removable supporting elements interposed between the chassis of the machine and the falling-object protective structure. In addition, the article proposes the numerical evaluation of the post-critical behavior of the analyzed mechanical system, using finite element analysis. The first part of the article briefly presents the main regulations in the field of falling-object protective structures, as well as the methods of approaching the evaluation of the performances imposed on these structures, with their advantages and disadvantages. Following are given the main aspects of the optimal modeling of structures for numerical analysis of their behavior, the particularities of numerical evaluation of post-critical behavior and some constructive solutions of dissipative elements. The final part of the article is dedicated to a case study and the author’s conclusions.

Authors: Gao F , Zong X M , Tian L , Quan S J 
Published: February 2021

Abstract
In the present work, the premature rupture of a spring used in the aviation sprag overrunning clutch of the helicopter was analyzed based on the general method for failure analysis by use of the investigations of the fracture surface, mechanical and chemical performance as well as the microstructure of the spring material. The results showed that spring breakage is mainly caused by mechanical fatigue. The cracks and fracture originated from internal surface of the spring, and the cracks extended from outside surface of the spring toward the external surface of the spring, which was consistent with the direction of tensile residual stress on the internal surface of the spring. The marks of the shot peening were obvious on the outer surface, while the inner surface had obvious metal flow lines, indicating that the residual tensile stress formed on the internal surface of spring. Moreover, the oxide inclusions were also detected on the internal surface of spring. It can be noted that the stress concentration on the spring internal surface and oxide inclusions are responsible for the fracture of the spring.
Effect of five versus two axle moving trucks on structural dynamic performance of frame bridges
Authors: Mohammed A , Almansour H 
Published: February 2021

Abstract
Recent advances in analysis, and design approaches led to a considerable reduction of the structural elements’ size and weight. Heavy multi-axle trucks are now standardized in North America, and elsewhere, the traffic speed and the average number of trucks passing bridges have dramatically increased. For the purpose of the design and/or assessment of bridge structures, it is imperative to evaluate the static deformations, frequency, vibration amplitudes, and dynamic deformation patterns of new and aged bridges due to the new five-axle versus the old two-axle design trucks. This study investigated the effects of using a recent standard multi-axle design truck on the dynamic performance of a frame bridge. It presents a comparison of the bridge dynamic performance under 2-axle and 5-axle moving trucks. A two-dimensional nonlinear finite element model is used to model the frame, and trucks are modelled as a multi-degree of freedom dynamic system integrated with the bridge model. It is found that the model is able to capture the local dynamic excitation and oscillations results from the high variation of the stiffness and mass of the bridge components.
Empirical correlation of heat generation in hybrid ball bearings, depending on the operational conditions in the aero-engine rotor supports
Authors: Lavrentyev Yu L , Petrov N I , Nozhnitsky Yu A 
Published: February 2021

Abstract
Modern gas turbine bearings operate at high rotational speeds. Their speed index reaches dmn=3…3, 5-106 mmrpm, where dm = bearing mean diameter, and n = rotational speed. At high speeds, significant heat is generated in conventional steel bearings, and substantial cooling oil consumption may be required. A promising solution to this problem is using hybrid bearings with steel rings and ceramic rolling elements. Due to ceramic’s relatively small coefficient of thermal expansion, hybrid bearings retain radial clearance in a wide temperature range. Hybrid ball bearings, with an inner diameter of 130mm and 150mm, were tested in the bearings test rigs at the Central Institute of Aviation Motors (CIAM). From these tests, an empirical method for determining the thermal state of the bearings was developed. The calculated values correspond well with the experimental data presented in the extant literature.

Published: February 2021

Abstract
OWL2, a widely-used ontology-representation language, is poorly perceived by humans because OWL2 statements have a low level of abstraction. To solve this issue, various OWL2 ontology editors are used, which allow to group statements and represent them using some visual notation. ORM-diagram is a good candidate for an intermediate model for authoring and understanding of OWL2-ontology as Object-Role Modelling notation supports visually distinguishable constructs, has the high expressive capabilities, and implements the node-link paradigm and the attribute-free approach A Protégé plugin allowing to create an ORM2-diagram using the live error checking approach was implemented. The plugin allows us to form a valid object-oriented diagram model in computer memory using a widely known ontology authoring tool Protégé.
