Diffusion modeling is essential in understanding many physical phenomena such as heat transfer, moisture concentration, and electrical conductivity. In the presence of material and geometric discontinuities and nonlocal effects, a nonlocal continuum approach, named peridynamics (PD), can be advantageous over the traditional local approaches. PD is based on integro-differential equations without including...
According to the mechanical failure of Gas Insulated Switchgear (GIS) in the earthquake will cause a great loss to the power system. This paper, by using the three-dimension design software to build a geometric model of 420 kV GIS, by using the finite element analysis method to make the mode analysis, and then acquired structural frequencies and mode features of the GIS, and by using spectral analysis...
In order to establish the finite element model of the knee-joint, force analysis applies on the knee-joints of persons are done first. The CT scanning images of a normal male volunteer's upper end of tibia are adopted, which are processed by Mimics 13.0 software to calculate a 3D model. Surfaces of the model are dealt by Geomagic 9.0 software and a smooth shell model is constructed. At the same time,...
One of the key research topics of the world's mining industry is how to ensure safe and reliable work of the powered supporot with large mining height more than 6m. During the process of design and development, the advanced CAD/CAE technique can be used to identify potential problems and increase the reliability of the powered support. In this paper, the whole 3D model of powered support with large...
This paper discusses the key technique of finite element modeling for complex precision forging part, which includes geometrical modeling, element type selecting, element meshing and remeshing, material model selecting, friction model definition and contact problem, In addition, the particular application of complex precision forging part in precision forming finite element modeling was shown combined...
The tests date to characterize the rubber material constants as well as the hyperelastic material stability is discussed. The rubber material of engine mount is analyzed based on different forms of strain energy potentials using finite element analysis software ABAQUS. The method of using test data to calibrate material coefficients is obtained. Both of the hyperelastic constitutive law and the viscoelasticity...
In this text, the method of deformation calculation for the thin wall member under shock load. We made research into impact, distortion of the thin wall member which is under constraint condition of freely supported beam by dint of emulation though MATLAB and the finite element analysis software ANSYS, the object of this research is aluminium alloy thin wall member.
Based on theory of equivalent mechanics, a model which consists of masses and springs is built to represent dynamical effect of propellant sloshing. In the deducing process, the problem is solved by constructing an elastic structure and running modal analysis in finite element structural codes. The process ensures the approach is more applicable than analytical methods and takes less computation duration...
Sometimes making finite element analysis only by one software is a hard thing. Because one software is not good at every work. Therefore, we choose ProE, HyperMesh and ANSYS software to model, mesh and calculate respectively and that can exert their corresponding advantages. Model can be imported and exported among softwares accurately with software interface. In ProE, surface modeling and model simplify...
The leads with heavy current passing through the covering plates, and the winding in a transformer, are sources of eddy current losses. Due to this loss some regions of tank wall are subject to serious local overheating. It affects the safety and reliability of this expensive object and power delivery. In this paper these eddy current losses are calculated through a new formulation by application...
