Abstract: Large wear debris is an important indication of abnormal wear of aviation engines. Analysis of the relationship between particle parameters and the output signal plays an important role to improve the sensor sensitivity. A three-coil simulating sensor model is constructed using APDL finite element program. After analyzing the influence factors to the induced output voltage of the sensor, such as debris material, location, size, exciting current etc, the fitting characteristic curves are obtained, realizing the quantitative analysis. Simulation results show that the sensor model can effectively distinguish between conductive and non conductive, ferromagnetic and non ferromagnetic debris. The induced voltage can reach 10^-4 V for the 500 microns ferromagnetic abrasive particles. The characteristic curves provide important basis for further research on sensor structure optimization.

Abstract: In the paper, combining the advantages of interface design of VB and secondary design of ANSYS, the electric calculating software for epoxy resin casting dry-type transformer was designed. In the procedure of designing transformer, designers only need to input the structure parameters and electrical parameters of the transformer, which would be transferred to ANSYS Parametric Design Language (APDL) program automatically. Then, the different loading conditions and post-procedure programs can be selected. Furthermore, VB calls ANSYS from the background program and reads the APDL file to calculate electric field distribution. Finally, the case analysis verifies that the software can establish the finite element model automatically and calculate the electrical field distribution under any fundamental frequency voltage and lighting surge.

Abstract: Since RCC dams huge volume and poor heat dissipation, thermal analysis plays an important role in the design and construction of RCC dams. This paper focuses on the application and verification of a two-dimensional finite element code developed for the thermal analysis of RCC dams. The effects of solar radiation and casting temperature were also evaluated in the analysis. The result has shown that, solar radiation has an evident influence on temperature history of both central and surface nodes in late ages, but contributes less to the temperature difference of them on the contrary. On the other hand, casting temperatures effect on temperature difference is obvious.

Abstract: In the manufacturing of large-tonnage forging equipment, heavy and redundant of the body structure components always result in increased manufacturing costs, high energy consumption and performance degradation. Therefore, the lightweight design of machine body becomes one of the important goals in green design of modern forging equipment. Firstly, based on the static and dynamic FEA of YQK-1250 frame hydraulic press body structure, the rational shape optimization results were analyzed through ANSYS Workbench. The thicknesses of the six related ribs were determined as the lightweight targets. Then, a preliminary lightweight optimization is carried out with orthogonal experimental design which provided approximate ranges for the further APDL analysis. Finally the improved lightweight design is optimized by the aide of APDL efficiently. It is validated that the mass is reduced by 4.52% with less influents on the overall performance.
