Abstract

The invention discloses a computer aided design (CAD) system for a composite type earth pressure shield cutter head, which belongs to the field of computer software. In the system, Solidworks 2008 is developed secondarily based on Visual Basic 6.0 to realize parametric modeling, and UDEC 4.0, MATLAB 7.0 and ANSYS Workbench 10.0 are called to perform automatic analysis and optimization. The system comprises a user input module, a basic function module, a performance analysis module, an optimization design module and a historical data management module. A user inputs geological parameters and technical requirements, and the system automatically combines theories of opening design, cutting tool type selection and cutting tool layout to perform basic configuration design, cutting tool geology adaptability type selection, cutting tool optimization layout, cutter head finite element stress analysis and cutter head structural parameter optimization design on the composite type earth pressure shield cutter head so as to obtain an optimal three-dimensional design result of a target cutter head, and the system automatically stores the data input by the user and a corresponding design result. By the CAD system, a corresponding relation between the geological parameters and key design parameters of the cutter head can be quickly established, and design reliability and design efficiency can be improved.

Description

technical field [0001] The invention relates to a CAD software system, in particular to a composite earth pressure balance shield cutter head CAD system, which belongs to the field of computer software. Background technique [0002] The shield cutter head is the only tool for cutting rock and soil of the shield machine, and its type, structure and adaptability to geological parameters determine the excavation efficiency and economy of underground space engineering. A large number of engineering data from all over the world show that the operation time of cutter head maintenance, tool inspection and replacement accounts for about one-third of the total excavation construction time, and the cost accounts for about one-third of the total excavation construction cost. Therefore, for various geological conditions, whether to design or select a shield cutter head that meets the needs of engineering construction has become a key factor in determining the success of the project. ...
