贝雷梁在进行有限元分析过程中往往采用梁单元进行模拟,这种模拟方法将贝雷梁的各构件简化为理想的杆件系统,而忽略了其局部效应。导致在某些情况下,采用梁单元的计算结果会失真。本文对比分析了梁单元与传统手算的结果差异性,并针对不同工程情况下采用梁单元与实体单元对其局部应力进行分析比较,总结了在某些工程情况下采用梁单元的局限性,为以后的工程提供借鉴。 Beilei beam element often used in the process of finite element analysis for simulation, this simulation method will Beilei beam components simplify the ideal rod system, while ignoring its local effects. As a result, the calculation results using beam elements may be distorted in some cases. In this paper, the differences between the beam elements and the traditional hand calculations are compared and analyzed. The local stresses are analyzed and compared using the beam elements and the solid elements under different engineering conditions. The limitations of beam elements in some engineering cases are summarized. For future projects to provide reference.
