This paper is primarily focused on finite element analysis and topological optimization of impact plunger and drill rod. Finite element method is an extremely functional, due to which we apply ANSYS software to analyze the stress and strain that impact plunger and drill rod bear in actual working condition and optimize their structure.

Drilling frame on TD165CH Down-The-Hole Drill that has large slenderness ratio and be longer than 10m is one component of Down-The-Hole drill which is mainly subjected to load.In the process of drilling, drilling frame is not only subjected to loads which are like tensile, compression and torsion and so on, and be under the influence of impacting and vibration of impactor,the situation of force is complicated.By analysing of working condition of Down-The-Hole drill,there get all kinds of limit states of typical working conditions, and then using Ansys doing finite element analysis, there get distribution of the stress and strain of drilling frame and the result of modal analysis to check whether drilling frame meets the requirements of strength and stiffness or not,and whether it is possible to resonate with the impactor or not.By analysis,Structure strength and stiffness of drilling Frame on TD165CH Down-The-Hole drill meet the requirements of practical engineering, and drilling Frame does not resonate with the impactor.

Y-branch is often used in connection between a main pipe and two branch pipes, for example, in furnace, quench boiler, nuclear parts and so on. The stress distribution in the Y-branch is very complicated because of complicated shape and complex loads on it. The stresses in the Y-branches cannot be determined by theoretical equations. Finite element method is used to analyze the stresses in the Y-branches. As an example, a Y-branch used in a high temperature furnace is calculated with ANSYS software. The temperature distribution and elastic and elastic-plastic stress fields in the Y-branch under mechanical and thermal loads are calculated. Strength, creep and fatigue of the Y-branch are evaluated based on T-1300, T-1400 of ASME Boiler and Pressure Vessel code Sec Ⅲ Div 1 Subsection NH.

Using the mechanical design of the software Solid works to established the 280 t LF the ladle furnace transportation car frame three dimensional model, and by using the finite element analysis of software Cosmos/works to static analysis for the frames, revealing that the frame of structure stress and strain distribution map of the frame, and also reveals that dangerous points and dangerous sections. Using resistance strain gauge to measure 280 t ladle transportation car frame, it is concluded that the frame of stress and strain distributions. Through the electrical measurement test the results were compared with finite element analysis results, further proof that the finite element analysis of the accuracy of the results provides theory basis for the optimization design of the frames.

Q43Y-85D type crocodile hydraulic clipping machine was taken as research object to optimization design. A finite element model for clipping machine was built using shell unit as fundamental unit. ANSYS12.0 finite element method was used to analyze the deformation and stress distribution of the shear platform model of hydraulic clipping machine. The result showed that the maximum equivalent stress at the dangerous area was 368.162 MPa and the maximum elastic strain was 0.1814×10-2 mm. After the structural optimization design, it was found that the maximum equivalent stress decreased to 186.238 MPa which did not exceed the material’s yield limitation 215 MPa and the maximum elastic strain decreased to 0.919×10-3 mm which satisfied the requirement of stiffness.

The cutter’s lateral displacement along the paper’s movement is the main reason which causes the folding accuracy problem. The folding stem is deformed in actual working condition, which causes the cutter emerge lateral displacement. The structure of folding stem is complex, it needs the combination of mechanics and finite element analysis to get the fitting formula relation of the folder’s deformation and the loadings. By the dynamic coefficients, which express the relation of loadings between the working velocity and clearances, the cutter’s lateral displacement model is established based on studying the relation of the cutter’s lateral displacement and the folder stem’s deformation. By the model, the folding accuracy is studied in different working velocities and conditions.

Using finite element method to simulate complex operations of the whole condenser under extreme water pressure, this paper aims at predicting the strength and stiffness of the condenser components under extreme pressure conditions. The results show that the max stress of the components is less than the allowable stress, and the max deformation is also within the permitted scope. The results will provide necessary reference for the further optimization design of condenser.

At present, it is inconvenient for use due to huge volume of common inflatable rubber fender. This paper introduces a design of cylindrical rubber sealing cushion which can be applied to various occasions to protect ships, dock and pier facilities. The key of air cushion technique is that it can produce a large displacement to buffer deformation and to reduce the exchange of energy. It plays a role to increase the time of collision, and then reduces the force of collision. Meanwhile, it also has good ability to adapt the tilted contact and it can float on the water surface, etc. This paper makes a feasibility analysis and strength calculation by doing theoretical calculation, and then making a force-test simulation by using ANSYS software, and do some structure optimal design according to the results of finite element analysis.

Gantry bucket wheel stacker-reclaimer belongs to large complex steel structure. Once it is instability at the working time that will make a large accident. So we have to calculate its strength and stiffness. But its connection and the working condition are very complex. And the size of the model is so large which leads to debase the calculation efficiency. This paper use Pro/E software to create the model. And use Pro/Mechanical to make a finite element analysis. Through the properly simplified the model, we can increase the calculation efficiency. During the calculation result we find that the Pulley yoke, Rigid leg and Flexible leg appear big stress areas. We will give an optimization design for the irrational place and high stress areas. So that to improve the Gantry bucket wheel stacker-reclaimer on-site safety. And provide a certain reference for the subsequent design and improvement.
