大型钢桁架结构设计与分析

Design and Analysis of Large-scale Steel Truss Structure

设计了一种应用于大型压力铸钢中的桁架结构,用于承载压力铸造设备。通过对桁架结构进行受力分析,确定了合适的杆件结构、各部件钢材型号以及钢轨安装方式,建立了桁架结构的简化模型,并应用ANSYS Workbench对桁架整体结构进行了有限元静力分析和模态分析,验证了所设计桁架结构的刚度和强度,确保运载小车工作过程中桁架结构的稳定性,避免其发生共振。

A kind of truss structure is designed for large-scale high pressure die casting.Truss structure is used to bear the pressure of the vehicle and the pressure casting equipment.Through the analysis of the loads on truss,the truss structure and the rail installation mode are determined.The simplified model of the truss structure is established,and the finite element analysis and modal analysis of the truss model are carried out by ANSYS Workbench,and the stiffness and strength of the truss structure are checked.The results show that the structure will not occur resonance in the vehicle working process.
