Abstract: Taking two commonly used blades types of adjustment baffles in practical engineering as research examples, analyses with 3D modelling were conducted by applying finite element software. Comparisons were carried out between the resistance characteristics and adjustment performance of two types of adjustment baffles through flow field analysis; meanwhile, comparisons were carried out between the stresses and deformations of two types of adjustment baffles through mechanical property analysis. Results show that, the flat plate blade baffle has better adjustment performance than the streamlined blade baffle, while the streamlined blade baffle has better mechanical property performance than the flat plate blade baffle.
