The hoist drum was analyzed with the finite element method analysis in this article .First, some necessary simplifications of hoist drum were handled and the solid model of reel was made by using of Pro / E. According to the concrete condition, we established material properties, generated the meshing and loads applied as well as other imposed constraints on the rolls based on ANSYS, and finally the hoist drum deformation and stress was solved. By analyzing the results, strain and stress distribution rolls are obtained.

Critical Investigation

This work attempts to make an investigation on the nature of material dependency of elastic-plastic contact behavior through a more accurate contact analysis between a deformable sphere and a rigid flat by finite element method. Analysis is carried out beyond elastic limit, till the inception of plasticity for various materials with different radii. It is found those materials with Young’s modulus to yield stress (E/Y) ratio less than 300 show strikingly different contact phenomena. Equation for hardness in terms of E/Y ratio for these materials is presented. A proposal for fixing the point of attaining fully plastic state is suggested. Existing disagreement over the dependency of hardness on material properties is critically examined.

A new structure is proposed to solve the failure mode of PDC cutter created by its mechanical fatigue, crack and diamond table delamination, so as to improve their service life. By applying the finite element method analysis, the force allocation of PDC cutter and multi-face (as known non-planar) designed PDC reinforced-cutter revealed that: the distribution and size of the internal stress in the cutter when working was improved, and the multi-face structure further reinforced the meshing force of the cutter’s PDC layer and cemented carbide substrate. And thus significantly strengthen the shear-resistance capability. This is particularly meaningful to the kinematics of mono-cone bit and its adaptive exploration of rock-breaking features, as well as to the related scientific disciplines in the future.

The different designs of rollers with varied convexity give different stress distribution and elastic deformation. It is directly related to the load capability and the life length of the roller bearing. With the Finite Element Method(FEM), by analyzing the stress distribution of roller busbar and raceway contact area in the design of different rollers with varied convexity of tapered roller bearing, the paper gets the best solution for the design of convexity of tapered rollers and the cause of roller bearings’ early destroy. The optimal result shows that the service life of this bearing has been improved by 93%. Hence, a more efficient method of improving the service life of rollers is got.

The purpose of the study is to assess through a FEM (Finite Element Method analysis), the behavior of a complex structure (enamel-tooth-alveolar bone-periodontal ligament-pulp), subjected to an external load through an orthodontic bracket-with forces of various intensities and to determine its influence on the entire structure.It is necessary to analyze the way all elements of the structure take over the external action given by the action of an orthodontic appliance through the brackets and the influence on the inner component -the pulp-inside of which there are the nerve endings.
