快装箱的静力学有限元模型参数的识别

Parameter identification for static FEM of plywood box

木包装设计系统软件中CAE应用于快装箱的静力学仿真分析时,如果直接利用小构件的性能参数,得到的仿真结果与试验结果不一致。为了使木包装设计系统软件CAE模型分析出的结果与实际相符,利用有限元方法和参数识别的方法识别出有限元模型的各个参数,识别后的模型的仿真试验数据与压力试验的数据一致。

The CAE of wood packaging design is used to static simulation analysis in this paper, the simulated result is not consistent with the laboratory result if the part of parameter of plywood box is used. For this reason, the finite element method and parameter identification are employed to define each parameter of FEM （finite element model） ,and the result is consistent with the experimental data.
