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.

The Finite Element Analysis

The active earth pressure on rigid retaining wall is analyzed using the finite element software ABAQUS. The fill behind the wall is sand and the Mohr–Coulomb constitutive model was used to model the stress–strain behaviour of soils.The finite element analysis results were compared with the Rankine results. The maximum error of the results is about 10% and the finite element analysis result is bigger. So the result obtained from the finite element method could safely be used in actual projects.

Dip Angle

The mechanism withstands 220t high temperature molten steel. In case of damage, molten steel pours. There will be major security incidents. Therefore, it is necessary to calculate carrying capacity of the mechanism. However, the part of components of the mechanism is made up of a crisscross of steel plate. This is used to withstand the bending and stretching. If we rely on traditional mechanical analysis, a large number of simplifying must be adopted, and accuracy of the calculation can be reduced. Therefore, this paper uses the COSMOSWorks Plug-in of SolidWorks software to carry out finite element calculation of whole machine for the mechanism. It avoids these shortcomings mentioned above. And this makes bearing capacity calculation to be more close to the actual circumstances. And the results show that: (1) the maximum stress of parts in the mechanism is only 52.8Mpa and much less than permissible stresses of its materials. As a result, the mechanism has sufficient bearing capacity. (2) The maximum displacement of whole machine is 2.637 mm. And the displacement will cause dip angle when lifting molten steel and it is less than its allowable stiffness. Therefore, the deformation is to meet requirements for the mechanism. In conclusion, the finite element analysis of the whole machine avoids complex force analysis and simplification of structure. The calculation has high accuracy. It is one of effective methods in the design of intensity and stiffness of complex structures.
