摘要
为了研究钢架的受力情况及可能的变形情况,根据某工程布袋除尘器钢架特点,采用实际工程数据基于ANSYS对钢架进行建模,考虑4种不同的工况并根据其具体特点,提出合理的约束加载方法及边界条件,研究分析了钢架在4种工况下的应力分布及变形情况。结果表明,用ANSYS建立的钢架有限元模型和计算方法合理,设计指标满足设计要求。该方法和结果为下一步研究布袋除尘器整体优化设计提供了理论依据。
To study the structure performance and potential collapse condition of steel frame, According to the characteristic of bag precipitator steel frame, the finite element model is established and the stress distribution and deformation under 4 different load cases are analyzed with ANSYS based on reasonable constraint loading methods and boundary conditions.The results show that the ANSYS model of steel frame and calculate method are rational, and the analysis is reliable for the design requirements. The results and method can provide reference and theoretical basis for the latter optimization design.
