ABSTRACT We present the results of a 3D global magnetohydrodynamic (MHD) simulation of an AM CVn system that was aimed at exploring eccentricity growth in the accretion disc self-consistently from a first principles treatment of the MHD turbulence. No significant eccentricity growth occurs in the simulation. In order to investigate the reasons why, we ran 2D alpha disc simulations with alpha values of 0.01, 0.1, and 0.2, and found that only the latter two exhibit significant eccentricity growth. We present an equation expressing global eccentricity evolution in terms of contributing forces and

Abstract:
With the increase request of strip quality, the roller eccentricity has become the important factor of influencing product quality. On the practical model of Cold-rolling Mill of 300, this paper establishes eccentricity compensation control practice of Cold-rolling Mill of 300 which applies wavelet transform method. Based on mufti-resolution decomposition of roll force signal by use of wavelets, eccentricity signals are separated from disturbances and noise,and self-optimization is employed to real-time control the roller eccentricity. The results show that the method is effective.

Abstract:
Geometric eccentricity errors inevitably occur in gear systems, resulting in the center of mass and center of rotation not coinciding. During the gear meshing process, the gear center distance and gear tooth meshing condition will change with time. In this paper, a model considering geometric eccentricity is proposed and a finite element model of the gear pair is developed. Finally, the dynamic response under different eccentricity and initial eccentricity angle is discussed. Based on Ansys, the simulation calculation of the gear pair is carried out, and the equivalent force maps of the danger

Abstract:
Eccentricity faults are one of the main causes that significantly affect the performance of permanent magnet synchronous machines (PMSMs). Monitoring eccentricity in real time could prevent failures by adapting operation conditions and maintenance schedule when early signs of deterioration are detected. This article proposes making a circuit-type model of a permanent magnet machine with an easily configurable eccentricity for simulations and real-time analysis of signals under different operating conditions. The basis for the construction of the circuit model will be the simulation of the PMSM

Abstract:
The problem of roll eccentricity has become one of important factors to affect the quality of strips as downstream industries require improvement of the strip quality. Reducing thickness control precision as little as possible is incompatible with restraining roll eccentricity perturbations on the requirement of the deadband size for the deadband drift method (DDM) with fixed deadband width. Therefore, the GM-AGC system in hot finishing mill of an aluminum plant uses the dynamic deadband eccentricity filter (DDEF) whose deadband width varies with the amplitude of the roll eccentricity signal.

The proposed method can rapidly determine the frequency range of the roll eccentricity signal by using the SFFT. Then, it divides the frequency range into several small frequency bands.

This research studies on behaviour precast wall loaded with a different eccentricity of load using finite element method. Seven (7) models of the wall were developed and analysed using ABAQUS software. All samples are designed with a dimension of 3000 mm height x 3000 mm length and 150 mm thickness by using the main material, which is reinforced concrete. Steel bar reinforcement for all model precast walls was provided with T10-200 in the vertical section and T10-300 in the horizontal section. The concrete grade used for the design of the precast wall in this study is the C35 with a longitudinal steel support of deformed steel reinforcement bars with a nominal yield strength of 460 MPa and for the mild steel is of 250 MPa. The study shows the decrease in deformation shape curve when the eccentricity value increases up to 10 mm. The study also reveals no significant effect on stress distribution regarding the location of stress under different eccentricities of load.

Abstract:
Vibrations play a very important role in rotor systems. In the manufacturing of the rotor system, the imbalance caused by the offset impeller and eccentricity produces unwanted vibrations. Various studies were carried out on unbalanced factors of rotor systems like eccentricity, crack, etc. But the effect of impeller offset due to manufacturing fault is not given much attention. In this study, the change in natural frequencies with respect to disc offset distance was calculated using numerical analysis and experimental analysis for the steel Jeffcott rotor system. Finite element analysis of the offset rotor shaft is carried out in the ANSYS workbench. Experimental modal analysis is carried out using the DAQ system. The accuracy of the model and the solution technique has been observed by comparing experimental results with the numerical simulation results from ANSYS. It is observed that when the disc is shifted from the center, it has a significant effect on transverse and torsional vibrational frequencies. As the disc is shifted towards bearing supports, the stiffness of the system increases, which leads to an increase in vibration frequency.

Abstract:
A model of growth modulation was formulated with variables integrating a biomechanical stimulus of growth modulation, a sensitivity factor to the stimulus and time. It was integrated into a finite element model of the thoracic and lumbar spine using an iterative procedure. A simulation on the personalized geometry of a mild scoliotic patient allowed qualitative investigation of scoliotic deformities over 12 cycles (months) in response to a load variation due to an eccentricity of the patient&amp;apos;s gravity line in the frontal plane. Resulting frontal, sagittal and transverse spinal views correspond to clinically observable scoliotic configurations. The simulation adequately reproduces a progressing thoracic scoliotic curve while the slight increasing kyphosis represents a possible condition although a thoracic hypokyphosis is frequently reported in the literature. At the thoracic apex, increased wedging as well as axial rotation evolving towards curve convexity are in agreement with clinical and experimental observations reported with curve progression. This study demonstrates the feasibility of the approach and, compared to other biomechanical models, it achieves a more complete representation of the scoliotic spine by incorporating vertebral growth modulation.

The open-circuit and load tests of transformers are routine and routine tests. The test equipment required for the open-circuit and load tests of large transformers is large in size and heavy in weight, and the process of repeatedly loading, transporting, and reassembling the test equipment on site involves certain transportation risks and low efficiency. In response to this problem in field testing, this paper uses SolidWorks to design a test platform for the open-circuit and load tests of 220 kV power transformers with a capacity of less than 240 MW. The test equipment, including variable-frequency power supply, intermediate transformer, current transformer group, and capacitor group, is integrated into two test vehicles. Through center of gravity analysis, 3D mechanical simulation, and design of fastening solutions, the final test platform is developed based on the analysis results. The test platform has been tested through long-distance driving and on-site testing, and the on-board equipment is stable and reliable, with no problems of eccentricity or displacement. The on-site testing efficiency has been improved by three times.

Abstract:
This paper studies on the fault analysis of 3-phase squirrel-cage induction motor with the rotor static eccentricity, the broken rotor bars, and the mixed fault at steady state. A mathematical fault model is presented by the coupled magnetic circuit approach. The Calculation of winding inductances is derived by means of a winding function theory. The concentrated winding type and the uniformly distributed winding type are used to taken into account the stator slot width effect. It is known that the calculation results of inductances of the concentrated type and the uniformly distributed type are almost similar. From the simulation results it is shown that there is its own peculiar frequency component obtained by the spectrum analysis of the stator current in the case of a single fault. But in the case of mixed fault, there is a mutual effect between two faults. From the comparison with FEM results, it is shown that the proposed approach can be simulated to diagnose faults in 3-phase squirrel-cage induction motor.

Abstract:
ABSTRACT Protecting the integrity of the wellbore is a major challenge for the sustainable development of hydrocarbon resources in nitrate formation. In this paper, A numerical model for investigating the effects of casing eccentricity on inclined wellbore integrity in salt-gypsum formation is developed. The effects of creep time, eccentricity distance, cement sheath modulus of elasticity and internal casing pressure on wellbore stress were investigated using the finite element method. The results show that for a given eccentricity, the stress on the wellbore increases with creep time, affecti
