Finite Element Analysis And Optimization Analysis On Steel-structure Pillar Components Of Large-scale Electrical Dust Precipitator

In this paper, aiming at the demerit of nonstandard design on electrical dust precipitator in our country, the strength, stiffness and stability of the steel-structure load-bearing pillars components of some type electrical dust precipitator were studied and the optimization analysis are calculated utilizing the large-scale popular FEA software ANSYS. Besides, the test of stress analysis is accomplished.Finite element analysis is calculated for these pillars components with the wavefront method. The strain and the stress distribution are studied and the results show the structure of the type electrical dust precipitator is safe and it can be optimized apparently.Optimization analysis based on the FEA result is calculated for these pillars with the zero-order method. The results of optimization analysis show that the OBJ descended clearly, since the gross mass of pillars components reduce by 41.6 percent and reduce by 31.6% after some parameters standardization. Thewhole effect after optimization is remarkably.The stress analysis test approved the reliability and the accuracy of the FEA analysis and provided testing foundation for theoretical calculation.This paper may give some direction to economize steels and cut cost for design & manufacture departments so that prominent economic benefit should be obtained.
