摘要

摘要: 受结构复杂性的影响，TBM刀盘的有限元建模过程将耗费大量的时间成本。基于APDL（ANSYS parametric design language）语言，研究了典型刀盘结构的有限元参数化建模方法，并通过模态实验对建模方法的可靠性进行了验证。结果表明：刀盘固有频率的计算值与测试值的最大误差仅为6.58%，按本文方法建立的刀盘有限元模型能够较好地反映实物模型的固有特性，可作为相关仿真计算的基础模型。研究结果可为刀盘的仿真分析及复杂结构的快速有限元建模提供参考。

Abstract: Due to the structural complexity, finite element modeling of TBM cutterhead will spend a lot of time. The parametric modeling method for finite element analysis of typical TBM cutterhead is established base on the ANSYS Parametric Design Language. And the modal experiment of TBM cutterhead is employed to verify the reliability of the modeling method. The results show that the maximum error between the numerical value and the experimental value of the natural frequencies of cutterhead is only 6.58%. The finite element model of the cutterhead accomplished by our method can well reflect the natural characteristic of physical model and it can be used as the base model of the related simulation. The study results can provide reference for the optimization design of cutterhead and the rapid finite element modeling of complex structure.
