摘　　要：为提升重型机械结构设计的安全性和可靠性,提出一种基于有限元分析的结构强度评估方法。该方法针对重型机械结构的特点,通过前处理及网格划分、非线性有限元求解、后处理及结果评估3个步骤,对结构的静强度、疲劳寿命和断裂风险进行系统分析。通过对某型号大型球磨机筒体的实际应用,验证了所提方法的有效性,为重型机械的设计提供了科学依据。In order to enhance the safety and reliability of structural design for heavy machinery,this paper proposes a structural strength assessment method based on finite element analysis.According to the characteristics of heavy machinery structures,the static strength,fatigue life and fracture risk of the structure are analyzed systematically through three steps:pre-processing and mesh generation,nonlinear finite element solution,and post-processing with result evaluation.The effectiveness of the proposed method is verified by the practical application of a large-scale ball mill cylinder of a certain model,which provides a scientific basis for the design of heavy machinery.
