采用Abaqus有限元软件,对热轧H型钢梁在侧向冲击荷载作用下的基本力学性能进行了参数分析。首先,通过与已有热轧H型钢梁受侧向冲击的试验对比,验证了本分析模型的可靠性;进而,采用该模型模拟分析和讨论了冲击能、冲击物质量、冲击速度等参数对H型钢梁在侧向冲击下动力响应的影响。结果表明:采用该文建立的有限元分析模型,可较好地模拟热轧H型钢梁在侧向冲击作用下的动力响应过程,冲击能、冲击物质量和冲击速度对钢梁的动力响应有不同程度的影响。该文的结论为H型钢梁冲击后剩余承载能力的研究奠定了基础。
Abaqus finite element software was used to analyze the basic mechanical properties of hot-rolled H-beam under lateral impact loading. First of all, the reliability of this analytical model is verified by comparing with that of the existing hot-rolled H-beam with lateral impact. Furthermore, this model is used to simulate and analyze parameters such as impact energy, impact mass and impact velocity Effect of H - Beam on Dynamic Response under Lateral Impact. The results show that the dynamic response of the hot-rolled H-beam can be well simulated using the finite element analysis model established in this paper. The dynamic response of the beam to the beam can be well simulated by the impact energy, the mass of the impactor and the impact velocity Have different degrees of influence. The conclusion of this paper lays the foundation for the research on the remaining bearing capacity of H-beam after impact.
