摘　　要：结合现场实测的中低速磁浮轨道梁动力特性分析结果,编写了中低速磁浮轨道梁的实桥参数优化程序,并提出了Python脚本对ABAQUS进行二次开发,结合模拟退火优化算法的修正方法,完成了双线连续轨道梁空间有限元模型的程序优化与计算;成功地对工程背景(25+35+25)m轨道梁初始有限元模型进行了修正。Based on the analysis of the dynamic characteristics of the mid-low speed maglev track beam measured in the field,the real bridge parameter optimization program for the low-speed maglev track beam is compiled,and the Python script is used to re-develop the ABAQUS and combine it with the simulated annealing optimization algorithm.The program optimization and calculation of the finite element model of the double-track continuous track beam were completed.The initial finite element model of the engineering background(25+35+25)m orbital beam was successfully modified.
