The Parametric Design And Optimization Of The Lifting Mechanism Of Vacuum Self-Consumable Arc Furnace

With the development of the vacuum metallurgy, the vacuum arc furnace is developing towards the trend of high efficiency and large scale, which leads the dimensional rise of the furnace and the rise of the load. Especially in the reconstruction of capacity of the furnace (three to five tons of the spindle), the original structure may lead the damage of the mechanical structure. So it is necessary to carry on the mechanical analysis for the furnace.Combination of research subjects, the article firstly describes the background, the meaning and the development of the situation around domestic and abroad. And then introduce the development platform of the system briefly, which includes the main principles of finite element analysis, finite element method of secondary development, visualization tools for VB and basic introduction of Vacuum Self-Consuming Arc Furnace.Combined with the self-consumable Arc Furnace VCF-3000 of ShenYang Vacuum Technology Institute, analyze the lifting mechanism with Vacuum Self-Consumable Arc Furnace. Based on the actual model, the actual model is simplified to mechanical model, for load-bearing components (e.g. column) of the mechanical analysis, get the largest stress part and the stress value to column. Then simply the model and establish finite element model, compare the stress model cloud and the values calculated, Inspection of existing finite element model is correct.Based on the finite element model existed, combined with the relationship between the size of the geometry of the model parameters, make the existing geometry modeling become parameterized, and be the parameterized finite element model of vacuum self-consuming arc furnace. Use of the optimize module of finite element analysis, on the base of the model to meet the strength and stability conditions, optimized the radius and thickness of the column and the furnace, makes the structure of strength in meeting the requirements of the quality to achieve the minimum, give full play to the material performance. At the same time applies visual language VB in ANSYS, designers can enter geometric design parameters through the windows, and can get optimized result of the analysis, makes ANSYS analysis to understand more easily and more intuitive.This article apples the finite element parameterization method to the design of the furnace. we can reduce the repeated workload in the serialization design, At the same time, the application of VB reduce the trouble and workload of the non-professional designers; insure the rapid and exact model construction process to get a referenced result.By the analysis to the result of parameter optimization, we can offer the theoretical foundation to the structure. It also can offer a significant reference to the modeling of the parametric design model. The parametric optimization method in this article is an important development of the parametric design method. It can get a utility value in the physical design by using the method.
