The Finite Element Analysis

In the traditional designs of milling cutter, we cannot get the required accuracy of machining as there may be local deformation on the edges, even more the cutter can break down. Aiming at this situation, a finite-element model of straight pin milling cutter with helical tooth are built using Marc, a nonlinear finite-element analysis software, the different cutting forces of the milling cutter during the cutting process are analyzed and the cutting forces of the milling cutter at different parameters are studied. We get the stress, the strain and the temperature distribution of the milling cutter in different situation. Our work offer a theoretical basis of improving stress of the cutter, designing the structure of cutters reasonably and analyzing the cutter failure as well as a new method of analysis and calculation of the cutter life and strength.

Abstract The effects of variations in stiffness and geometry on the nonuniformity of tires are investigated by using the finite element analysis. In order to evaluate tire uniformity, a three-dimensional finite element model of the tire with imperfections is developed. This paper considers how imperfections, such as variations in stiffness or geometry and run-out, contribute to detrimental effects on tire nonuniformity. It is found that the radial force variation of a tire with imperfections depends strongly on the geometrical variations of the tire.

Based on the model experiment on seismic behavior of a 1-span, 2-story concrete-filled rectangular steel tubal (CFRST) frame under lateral cyclic loads, a 3-D nonlinear finite element model of concrete-filled rectangular steel tubular frame is proposed in the paper. Compared with the experimental hysteresis curve, the computational results are found to be accurate, which shows that this model proposed in the paper can be applied in structure analysis of concrete-filled rectangular tubular frames. So the model was used in the finite element analysis of concrete-filled rectangular frame with different axial load level. Compared the computational displacement envelop curves, it concludes that the ductility and bearing capacity of CFRST frames reduces with the increasing axial load level.

Strain clamp is an important connection device in guy tower. If the quality of the compression splicing position is unsatisfied, strain clamp tends to be damaged which may lead to the final collapse of a guy tower as well as huge economic lost. In this paper, stress distribution on the compressible tube and guy cable is analyzed by FEM, and a large equivalent stress of guy cable is applied to the compression splicing position. During this process, a finite element model of strain clamp is established for guy cables at compression splicing position, problems of elastic-plastic and contracting are studied and the whole compressing process of compressible position is simulated. The guy cable cracks easily at the position of compressible tube’s port, the inner part of the compressible tube has a larger equivalent stress than outside.
