PERFORMANCE EVALUATION TECHNIQUES FOR THE NUCLEAR GRADE MAIN FEED-WATER CONTROL VALVE by LIU QingMin, GAO ZhaoJie, LIN Feng, ZHANG QiangSheng, WU Xin

“…A performance evaluation technology was studied for the seismic performance evaluation of nuclear safety Class II main feed-water control valve based on the ASME Code and finite element analysis platform（ Femap + NX Nastran）.First,we proposed an analysis model for the vertical control valve,and the risk assessment and improvement methods for the structural characteristics of vertical control valve were studied.Then we conducted a numerical model for a control valve and compared the simulation data with those obtained from experimental test.These two showed good agreement.Finally,the seismic performance evaluation of a main feed-water control valve was performed under the combination of the seismic load and design load.The simulated relative error of inner stresses at typical site is less than 5% compared with that obtained by using empirical formula.The simulated data shows that the designed valve fulfills the design requirement for its first order frequency is bigger than 33 HZ,and the maximum stresses are within the allowable range under various load cases.…”

800 kV交流隔离开关的机构运动分析及平衡弹簧优化设计 by 孙玉洲, 李付永, 郭海涛, 王巧红, 夏立国, 师丽芳, 刘本学, 柴影辉

“…800 kV AC disconnector is one of the key equipment for extra high voltage（ EHV） substation,and the balance spring is an important component to reduce external load and improve equipment reliability.Aiming at 800 kV EHV disconnector,the mechanism kinematic analysis of main knife mechanism is completed based on the motion diagram,and the theoretical equation of the structural potential energy for disconnector is obtained.Then,the dynamic simulation analysis model of disconnector is established in ADAMS through virtual prototype technology.The difference between the elastic potential energy of the balance spring and the potential energy of the mechanism under the initial design condition is simulated.In order to further narrow the gap between the spring energy and the gravitational potential energy,this paper optimizes the spring system design.The simulation results show that the max-gap change between the optimal balance spring potential energy and the mechanism potential energy is reduced by about 28% than that of the initial.When the disconnector works,the external load required is greatly reduced.…”

INVESTIGATION ON FINITE ELEMENT MODELING METHOD OF WITH TRIPLE JUNCTION POLYCRYSTALLINE INTERGRANULAR FRACTURE by SHI JunLin, ZHAO JianPing

“…Cohesive zone model was used to simulate polycrystalline intergranular fracture at the grain level model,the finite element model build-ing reflected the actual situation is a difficult point.In this paper,Mixed Programming of Matlab,Python and Abaqus,An algorithm was presented which can easily and quickly generated Voronoi geometric model and the grain sizes distribution agrees with lognormal distribution.Realized the automatically insert the zero-thickness cohesive interface element by writing nodes and elements at crystal boundary,firstly solved the void zone at the intersection of the three zerothickness cohesive element,which is the triple junction,And to make up the defect of cohesive zone model.The whole process of the finite element analysis was performed automatically by secondary development,including the assignation material properties,material orientation,load application,model solution.Finally,polycrystalline aluminum was used as an example to simulate the intergranular fracture process without the initial damage.The results show that the method is more effectively and practically,which can be used to simulate polycrystalline intergranular crack initiation and propagation in random microscopic grains.…”

Graph-Based Symbolic Technique and Its Application in the Frequency Response Bound Analysis of Analog Integrated Circuits by E. Tlelo-Cuautle, S. Rodriguez-Chavez, A. A. Palma-Rodriguez

“…The derived H(s) of a given analog IC is used to compute the frequency response bounds (maximum and minimum) associated to the magnitude and phase of H(s), subject to some ranges of process variational parameters, and by performing nonlinear constrained optimization. Our simulations demonstrate the usefulness of the new GBST for deriving the exact symbolic expression for H(s), and the last section highlights the good agreement between the frequency response bounds computed by our variational analysis approach versus traditional Monte Carlo simulations. …”
