矩形盾构受力缩尺模型设计及Ansys仿真研究
|
摘要
对矩形盾构掘进时的垂向及轴向负载进行分析,得出矩形盾构在较复杂条件下的垂向、轴向负载模型;设计一套用于模拟盾构掘进受力的缩尺实验装置,并对其部件进行阐述;应用ANSYS应用ANSYS自带优化功能,对缩尺模型参数进行优化。该研究为矩形盾构受力缩尺模型设计提供指导。
The vertical and axial load of the rectangular shield were analyzed,and the vertical and axial load models of the rectangular shield under complex conditions were obtained. A set of scale experiment device was designed to simulate the force of shield tunneling. The static analysis and modal analysis of the rectangular shield scale platform were carried out with the application of ANSYS software. The parameters of the scale model were optimized with the optimization function provided by ANSYS.It provides guidance for the design of the rectangular shield force scale model.
