摘要:
根据某土压平衡盾构刀盘结构特点,在Solidworks中建立其三维实体模型,并应用ANSYS软件建立了刀盘相应的有限元计算模型,对刀盘在正常工况和脱困工况下的受力特性进行分析,得到了刀盘在各工况下的应力应变分布规律.分析结果表明,危险截面位于180～210°辅梁与辅条间,在牛腿与法兰盘、辅梁连接处也有较大应力,最大应力为204 MPa,最大变形为1.568 mm,研究结果为刀盘的结构设计和工程施工维护提供了基础数据.
Abstract:
According to the structural characteristics of a cutterhead of an EPB shield, a three-dimensional solid model was established in Solidworks, and the corresponding finite element calculation model of the cutterhead was established by ANSYS software, and the stress and strain distribution law of the cutterhead under normal working conditions and escape conditions was analyzed, and the stress-strain distribution law of the cutterhead under each working condition was obtained. The analysis results show that the dangerous section is located between the auxiliary beam and the auxiliary bar at 180~210°, and there is also a large stress at the connection between the corbel, the flange plate and the auxiliary beam, the maximum stress is 204 MPa, and the maximum deformation is 1.568 mm, and the research results provide basic data for the structural design and engineering construction maintenance of the cutterhead.
