摘　　要：针对某钢厂250 t钢包车车架结构的变形和局部破损问题,采用有限元方法对车体与钢水包开展静力学仿真。建立钢水包与钢包车的三维几何模型,将几何模型导入Hypemesh;建立三维有限元模型;将有限元模型导入ANSYS的结构分析模块进行计算。结果显示,原有钢包车长期使用后会出现局部破坏,并且和现场一致。基于计算结果,对车体结构进行优化,显著提高了车体的局部强度和整体承载能力。With regard to the deformation and local damage of the frame of a 250 t ladle car in a steel plant,the finite element method is used to carry out the static simulation of the car body and the ladle.The three-dimensional geometric model of ladle and ladle car is established and introduced into Hypemesh,by which the three-dimensional finite element model is built.The structural analysis module of ANSYS,by import of the finite element mode,is conducted for calculation.The results show that the original ladle truck will be damaged locally in long term use,and is consistent with the site.Based on the calculation results,the structure of the car body is optimized,and the local strength and the overall bearing capacity of the car body are improved remarkably.
