Research on Technology of Variant Design for Main Frame of Tunnel Boring Machine Based on KBE

The main frame of full face rock tunnel boring machine (TBM) has very complex configuration, function and space constraint relation. Aiming at these problems, a new method of variant design for TBM main frame based on KBE is proposed. The modularization variant project configuration for TBM main frame is designed with integrating KBE and modular design method. Moreover, the method can realize parametric drive and detailed design of modular configuration and carry out variant design of TBM main frame rapidly. The frame of variant design for TBM main frame is researched and presented based on KBE. And those key techniques are researched, which include the technique of modularization project configuration for TBM main frame based on KBE, module parameterization modeling technique based on KBE and variant design process based on KBE. Finally, the variant design for TBM main frame can be realized through database technique, programming language VC#. NET and CATIA software. This method greatly reduces the complexity of product developing and effectively shortens product developing cycle.
