Abstract: This paper takes the butt joint of axle case steel as research object, simulates the real-time three dimensional dynamics CO2 shielded welding of welding stress field by FEM software ANSYS and obtains the axle case steel 390Q’s transient stress field of weld zone at different welding speed. On that basis, the feasible dynamic simulation method of three-dimensional stress welding field which provides theoretical basis and guidelines for optimizing welding technology and norm welding parameters was proposed. The result of welding stress simulation shows that the welding stress is the lowest when the optimum welding speed is 5mm/s.

Abstract: The layered construction technique is the common method of large steel structures in the non-slide construction. In process of the former three-tier construction, the structure is prone to forming large deformation because of great span, large weight of interlayer equipments and other various factors. In this article, to obtain high dimensional accuracy and good deformation control data, the positions of temporary support points of the 3M201 that is a module of large steel structure in a project are optimized successfully with the ANSYS optimization of finite element.

Abstract: In this paper, a cylinder involute gear model is established in AUTOCAD2007 software. SAT file format is imported in the ANSYS software and contact stress on gear meshing position is analyzed. The stress distribute drafts of the gear is obtained so that it is convenient to check the bending strength of the root of the gear and the fatigue contact strength of the face of the gear. The result is similar to the real situation. The whole process of model construction, analysis shows that ANSYS software is a reliable and effective tool which could provide theoretical basis to the gear teeth strength designation.

Abstract: Micro-structural gas sensor with a new kind of electrode is designed. Platinum filament is selected as gold electrodes, and SiO2 is used as the thermal and electricity insulation layer. The simulation results of ANSYS reveal that when the thickness of SiO2, thickness of Si substrate, electrode with and electrode space are 50, 250, 15 and 60 µm, respectively, the sensors can own higher temperature and uniform temperature distributing in the center. The magnetic field distribution is also analyzed by ANSYS, and the results show that the new electrodes can eliminate magnetic field from the heater on the measuring signal interference, which is benefit for the improvement of sensor performance.
