The technologies of repairing the worn parts of metallurgical equipment using plastic deformation methods, namely, expansion, swaging, upsetting, pressing, knurling, and forge-rolling, are described. Recommendations are given to choose temperature conditions in repairing the parts and determining the deformation forces.
This paper presents the simulation of cantilever beam using ANSYS for nano manipulator. Steel, Aluminum alloy and Polyethylene have been used for design of beam type structure. The structural analysis has been conducted by applying the force of 0.001 μΝ to 0.8 N. The length of beam has been varied from 80 μm, 120 μm, 160 μm, the width has varied 10 μm, 20 μm, 30 μm and the thickness has been 0.6 μm,...
The processes of pipe collapse under external pressure have be calculated and simulated by means of the ANSYS FEA. It introduces the destruction theory of the pipe and some formula by API, and analyses the factors such as geometries, pressure, and its properties, which affect the capability of the resistance to the pipe collapse. The relationship between strain and stress of pipe has been descried...

According to engineering geological conditions in return airway of 1251(3)Pans an colliery, and distribution of advance abutment pressure, roadways supporting...
Based on the pitting corrosion characteristics of corroded deformed steel bars embedded in concrete structures in chloride environment, the Finite Element fine Model is established by the ANSYS FE software, and nonlinear analysis was conducted for the influence of corrosion pit on the resistance properties of steel bars. Results show that the effect of pit location is apparent on the mechanical properties...
During the design of the second-phase extension project of a fuel electric plant in China, in order to meet the technological requirements, a typical oval steel coal scuttle with double funnels was proposed. This kind of scuttle has a complicated geometrical shape and is difficult to be designed and built. To evaluate the mechanical behavior of this scuttle, the 3D finite element structural analysis...
Plastic helical gear and steel worm pair is a transmission mechanism in which plastic helical gear is substituted for metal helical gear to transmit power and movement. In the transmission process of worm and helical gear drive, there is large relative velocity on the meshing area and that the plastic gear is sensitive to the environment temperature and humidity and liable to lead to failure. So it...
The fine blanking process with stepped-edge punch was analyzed by finite element method for different curvature parts. Distributions of hydrostatic stress on deformation zone were obtained for different curvature parts. An experiment device has been designed and made for one automobile part by fine blank process with stepped-edge punch. The reasonable forming parameters were adjusted according to...
Numerous connections brittle fracture happened in the Wenchuan Sichuan earthquake, which indicates that cognitions on the damage mechanism of beam to column connection are rather inadequate. It need to improve in constitution, there are four kinds of connections are analyzed by the finite element. Under the repeat load, which seismic behavior of improved connections are better and can satisfy the...
In order to realize numerical simulation of hot rolling and establish the hot deformation process parameters for X80 pipeline steel, the flow stress behavior of X80 pipeline steel during hot deformation was investigated in the temperature range of 900-1100°C and strain rate of 0.01-1s-1 on Gleeble-3500 thermo-simulation machine. The results show that dynamic recover and dynamic recrystallization occur...

With the development of science and technology in recent years, the large-span spatial structures is one of the fastest growing form of the structure. Because large-span spatial structures are very complex and the construction cycle is long, the impact of internal forces and deformation is relatively large for construction of structures. The constructional mechanic combines structure mechanic and...
