This document mainly studies the cross-section shape of the box-type telescopic boom. First, the basic structure of the telescopic boom was analyzed, and then, the finite element analysis of the quadrilateral and hexagonal telescopic booms were conducted based on ABAQUS with the same section height, width, thickness, as well as the same constraints and loads condition. The stress-strain diagram was obtained. Comparing to the quadrilateral boom, the hexagonal telescopic boom loads higher, weights lighter, and performs better.

Elastic Distortion

The untwist of rotating blades in turbomachines treated so far in the literatare simply as a pure elasticity problem is generalized and formulated rigorously as a problem of aeroelasticity by variational principles (VPs) and generalized VP (GVP). It takes into account not only the centrifugal force, but also the aeroelastic interaction between blades and the flow as well as the elastic distortion of the cross section shape of blades, assuming the material to be linearly elastic but nonisotropic. Thus, a new rigorous theoretical basis for the finite element analysis of blade untwist in turbomachine design is provided.

With the ongoing development of product process, there is a growing demand on micro products. Though the macro-drawing process has been well-developed, the design concepts may not be directly applicable to the micro-drawing due to the size effect occurred in the micro-forming processes. In the present study, experiments were conducted first to establish the stress-strain curves, r-values and work hardening exponents of 304 stainless steel sheets with different grain sizes. The experiment results reveal that the stress-strain and r-value become smaller and the work hardening exponent increases for larger grain sizes. The difference between stress-strain curves in various directions of 0°, 45° and 90°, respectively, is significant when the grain size increases. The stamping of a vibration motor shell of cell phone, which bears a circular cylindrical shape, was also examined in the present study. The finite element simulations were performed to evaluate the formability of the multi-stage drawing process with initial die design. The forming characteristics were identified and an optimum die design was then developed with the use of the finite element analysis. The stamping process with multi-stage tooling design based on the finite element analysis was implemented and the actual stamping experiments were conducted to verify finite element analysis. The experimental results confirm the validity of the modified tooling design and the efficiency of the finite element analysis.

According to the factual demand of produce, some corporation wants to enlarge the capacity of the idle from 65t to 75t. This paper aims at the changing ladle which the capacity is 75t. It makes research to the iron ladle's promotion process and stress analysis. This paper uses ANSYS-Workbench software to make the finite element analysis of the iron ladle and extracts the largest stress, strain and the location. Then this paper analyses whether the changing ladle can be fit for the intensity demand or not so that it could provide the important theory gist to the corporation

Forging Force

The process of precision forging has been developed recently because of its advantages of giving high production rates and improved strength. For complete filling up, predicting the power requirement and final shape are important features of the forging process. A finite element method is used to investigate the forging force, the final shape and the stress distribution of the parking sensor shell forging. The stress-strain curve of AL-6082 is obtained by the computerized screw universal testing machine. The friction factor between AL-6082 alloy and die material (SKD11) are determined by using ring compression test. Stress-strain curve and fiction factor are then applied to the finite element analysis of the parking sensor shell forging. Maximum forging load, effective stress distribution and shape dimensions are determined of the parking sensor shell forging, using the finite element analysis. Then the parking sensor shells are formed by the forging machine. Finally, the experimental data are compared with the results of the current simulation for the forging force and shape dimensions of the parking sensor shell.

Deflection and stress of different cross section forms and its value are compared by finite element analysis of timberwork design model under the impact loading. The result indicates that decreasing the size of cross section or changing the section shape can effectively avoid the model too heavy and conservative design. In the case of horizontal loads applied on first floor, strengthening the column of first floor obviously reduces the deflection of model and improves the lateral stiffness. Keeping the column size of the first floor and choosing I-section significantly reduce the overall weight on condition of meeting the bearing capacity and stability, it also make the material higher utilization.

The Finite Element Analysis

The design of structural modeling is usually based on the different geometric function. Since every component has a definite life span, it is necessary to calculate its core parameters. To find the life span of component, the component must be as input parameter to the Finite Element Analysis. The Finite Element Analysis is nothing but a numerical method for solving Engineering and Mathematical problems. The Analysis of the “Rear Axle Casing of Tractor” using cast iron material with special grade “SG 500” for already existing model, taken in the real time is done by using “ANSYS”. The stress, strain, deformation analysis of the component is done by giving various boundary conditions. These analyzed results help to redesign the rear casing of tractor. The redesigning of rear axel casing of tractor is done using “PRO/E”. During redesigning the component, various criteria’s taken in the real field must be taken into an account. The analysis of the redesigned model is done by giving various boundary conditions for both materials ‘SG 500” and “SG 200”. Then the stress, strain, deformation, structural supports, structural results are evaluated and also cores, dies and patterns are generated and hence the redesigned rear axel casing of tractor is found to be in safer mode. And also the better material for the rear axle casing is given, by comparing the above mentioned materials.

In order to study the force capacity of the cross steel reinforced concrete special-shaped column in horizontal load, the finite element analysis software ABAQUS has been used. We adopt a horizontal direction displacement loading method to apply horizontal load, and its displacement is 20mm. We simulate the stress distribution of the six rates of steel bone and the six different cross section sizes of steel reinforced concrete special-shaped columns. According to the result, the load - displacement curve has been dropped, and we analyze the mechanical properties of cross steel reinforced concrete special-shaped column by the curve. The results show that the bearing capacity of cross steel reinforced concrete special-shaped column has improved with the increasing of rate of steel bone and the cross section size.
