“…Using numerical simulation to analyze the welding process of large structural parts, the advantages of fnite element simulation in calculating the hardening properties of elastoplastic materials can be efectively used [14][15][16]. In practical engineering applications, welding deformation will often accompany the welding process [17,18].…”

Considering the stringent requirement of the pointing accuracy up to 2.5″ of the world’s largest full steerable radio telescope, this paper studies the welding experiment of the azimuth track of the antenna. First, the opposite deformation jig and welding process were designed for the QTT’s azimuth track. Then, the welding process was numerically simulated using a finite element model. The simulation results show that a better welding effect will be obtained by appropriately reducing the opposite force on the basis of the original. The three deformation processes of the track are regulated by the opposite deformation jig. The results show that the opposite deformation jig designed for QTT’s azimuth track can make the amount of deformation and flatness meet the design requirements. Finally, nondestructive testing was carried out to check the welding quality of the track surface and interior. The results show that there are no obvious defects in the welds of the azimuth track. The constraint jig and welding processes designed for QTT are effective and feasible.

Design of forging dies is tedious, tedious and complex process, which is a skill-based activity, and it needs more effort and time, the specialists in the design of the collection of knowledge-forging dies of knowledge and expertise are necessary for the design process. The aim of the present work is to study Computer Aided design of Connecting rod. This is done by analyzing the elements of design and knowledge experience, establishing knowledge bases, using Visual Basic to link knowledge bases and Solid Works. This system is experimental. The results indicate that the benefits of using this system to save time and effort and reduce errors caused by designers and improving the design quality.

“…The optimum die profile has been obtained by Azad et al, 2005, considering work hardening of the material in cold extrusion, on the basis of minimization of stress and load in die-work piece contact surface by using a developed computer program. Knoerr et al, 1992 has investigated the die fill, defect analysis and prevention, as well as for the prediction of part properties by using DEFORM FEM software. Kim et al, 1994 have summarized the results of industrially relevant "work-in-progress" research with the DEFORM-2D and 3 D systems.…”

The curved die plays a significant role in reduction of extrusion load, refinement of microstructure and improvement in quality of product. In the present investigation, a numerical FEM modeling has been carried out for extrusion of triangular section from round billet through a curved die using DEFORM-3D software for steady state deformation using rigid plastic material. The extrusion load has been predicted. The effective stress, strain, strain rate velocity and temperature distribution have been determined. An experimental test rig has been fabricated. The experimental results are compared with the theoretical results. The results of computations are found to be in good agreement with those of the experiments.
