【摘要】：利用有限元軟件ANSYS Workbench對切向矩形開孔旋風(fēng)除塵器的受力進行研究,分析比較了矩形接管未經(jīng)加強和矩形接管經(jīng)加強筋加強后兩種情況下開孔接管部位的應(yīng)力分布以及變形情況,并采用線處理法對應(yīng)力進行均勻化和當(dāng)量線性化處理,依據(jù)JB 4732—1995進行應(yīng)力分類和校核。結(jié)果表明:經(jīng)加強筋加強后的旋風(fēng)除塵器在開孔接管部位的變形明顯減小,應(yīng)力分布更加均勻;與未加強結(jié)構(gòu)相比,最大等效應(yīng)力由609.75 MPa降為434.6 MPa,有效降低了應(yīng)力集中程度,結(jié)構(gòu)強度得以提高,可滿足強度要求。研究中,加強筋的設(shè)置方式能有效提高矩形開孔接管部位的結(jié)構(gòu)強度,可為壓力容器切向矩形開孔結(jié)構(gòu)的加強設(shè)計提供參考。
[Abstract]:Using the finite element software ANSYS Workbench, the stress distribution and deformation of the tangential rectangular perforated cyclone dust collector are analyzed and compared under the condition that the rectangular pipe is not reinforced and the rectangular pipe is reinforced by the reinforcement of the reinforcing bars, the stress distribution and the deformation of the opening pipe are analyzed and compared, and the stress distribution and the deformation of the rectangular nozzle are analyzed. The stress was homogenized and linearized by the line treatment method, and the stress classification and verification were carried out according to JB 4732 / 1995. The results show that the deformation of the cyclone precipitator strengthened by reinforcement bars decreases obviously and the stress distribution is more uniform. Compared with the unreinforced structure, the maximum equivalent stress is reduced from 609.75 MPa to 434.6 MPa, the stress concentration degree is reduced effectively, and the strength of the structure is improved, which can meet the requirements of strength. In the study, the arrangement of reinforcement bars can effectively improve the structural strength of rectangular orifice nozzle, which can provide reference for the design of tangential rectangular opening structure of pressure vessel.
