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.

With the popularity of the Internet, people have higher and higher requirements for industrial product (hereinafter referred to as IP), which requires us to continuously enhance the Interaction design (hereinafter referred to as ITD) in industrial product design (hereinafter referred to as IPD). Through ITD, we can improve work efficiency, which will strengthen the connotation of the product and the idea of expression. ITD is one of the earliest methods applied in the field of computer, which will improve the communication between human and computer in vision, hearing, touch and other aspects. However, with the rapid development of computer technology, the concept of ITD has been applied to industrial design, which has become the main method to achieve functional interaction. Through the concept of ITD, we can meet the needs of society, which will improve the interaction between human and industrial design. Interaction is bilateral, which will be affected by both human and industrial design. Therefore, we must strengthen the application of network ITD in IPD. Firstly, this paper analyzes the value of interactive design in industrial design. Then, this paper analyzes the main methods of interactive design in IPD. Finally, an application example in IPD is presented.
