摘　　要：以第十六届黑龙江省大学生结构设计竞赛命题为背景,使用Midas Civil有限元软件对某校参赛模型桥梁结构选型和力学性能分析方面进行论述和总结。以某大桥为参考依据进行方案设计,通过Midas Civil有限元软件建立3D桥梁模型,从强度、刚度和稳定性等力学性能研究。在符合材料性能的情况下,通过细部处理减轻模型质量。实验结果表明,模型最终可以降低重量,说明所提出的方案设计及细部处理符合要求。Based on the proposition of the 16th Structure Design Competition for College students in Heilongjiang Province,Midas Civil finite element software is used to discuss and summarize the structure selection and mechanical performance analysis of the bridge model in a university.The scheme was designed based on a certain bridge,the 3D bridge model was established by Midas Civil finite element software,and mechanical properties such as strength,stiffness and stability were studied.The quality of the model is reduced by detailed treatment,where appropriate for material properties.After many experiments,the weight of the model can be reduced,which shows that the proposed scheme design and detail processing meet the requirements.
