Finite Element Analysis And Optimization Analysis On Steel-structure Mudsill And Bracket Assembly Of Large-scale Electrical Dust Precipitator

The mudsill and bracket of RWD/QX--48 X1X 2 electrical dust precipitator act as the primary study subject in this paper, and finite element analysis and optimization analysis are made by use of large-scale finite element analysis software I-DEAS, aiming at the demerit of nonstandard design on electrical dust precipitator in our country.Solid model is made for mudsill and bracket using I-DEAS, and finite element static analysis is carried out, on the base of terminal conditions setting for the overall structure and defined restrain. The analysis study concentrate on the distribution of displacement, stress, strain energy etc. of mudsill and bracket. The results show the structure of the type electrical dust precipitator is safe and it can be optimized apparently. And the accuracy of I-DEAS in calculation to mudsill and bracket is verified by use of analogical calculate method.Each component optimized step by step based on overall structure, in the process of optimizing to the mudsill and bracket according to the results of FEA. The results show that the assemble mass of mudsill and bracket reduce by 3437kg, andgross mass reduce by 16.6 percent. The whole effect after optimize is obvious. The module is refreshed using the optimized result, and the rationality and reliability of the optimized result are testified afterward.This paper may give some direction to economize steels and cut cost for design & manufacture departments so that preferable economic benefit would appear.
