Study on Digital Integrated Design of Shield Cutter Head

传统方式对复杂的盾构刀盘参数化模型进行结构分析与优化时,需要大量的手动干预,整个分析过程冗繁且效率低下。针对这一缺陷,提出刀盘结构参数化设计和自动分析与优化的方法。基于参数化盾构刀盘建模系统,通过建立简化规则和评判标准,自动实现盾构刀盘参数化模型简化;应用二次开发原理与数据库技术,开发SolidWorks与ANSYS之间的通用化信息接口,实现参数化设计和有限元分析一体化的功能。算例运行表明:通过输入关键参数,所开发的试验系统不仅可完成整个盾构刀盘的结构设计,而且还能实现其模型的结构分析与结构优化,极大地减少了产品设计和优化的工作量,缩短了其研发周期。

In the traditional way,the structural analysis and optimization of the complex shield cutter parameterization model requires a lot of manual intervention,and the whole analysis process is tedious and inefficient.Aiming at this defect,the parameterized design and automatic analysis and optimization method of the cutter head structure are proposed.Based on the parameterized shield cutter head modeling system,through the simplified rules and evaluation criteria,the parameterized model of the shield cutter head was automatically simplified.The secondary development principle and database technology were applied to develop the information data interface between SolidWorks and ANSYS.By use of this interface,the integration of parametric design and finite element analysis can be realized.The test example shows that the developed system can not only complete the structural design of the entire shield cutter head,but also realize the structural analysis and structural optimization of the model,greatly reducing the workload of product design and optimization,and shortening the development cycle of the product.
