Study on Dual-mode Modeling Approach of Caxa

This paper presents a dual-mode modeling approach based on innovation design and engineering design, which is applied to the design of belt conveyor. Dual mode modeling method fusions innovation design pattern and engineering design mode, and realizes a combination of liberalization design and precision design, while the traditional parametric modeling is restricted by single thought, which exists a strictly relationship of father and son between part elements, but dual mode modeling approach breaks the restriction. This paper firstly described the characteristics of dual-mode modeling method and the function of 3D sphere uniquely owned by software Computer Aided X Alliance(CAXA); then the theoretical design process of belt conveyor was introduced, which included driving power calculation for drum, selection of driving motor, selection of gear reducer and confirmation for idler diameters; the modeling process of belt conveyor was described through the application of the dual-mode modeling method, the whole product modeling design has included module design and assembly design, and has accomplished the driving device module, and roller device module, and transmission device module design. The results show that the modeling speed with dual mode modeling approach can increase one time compared with the traditional methods, and all the technology application above can improve the design efficiency, reduce design error, thus greatly improve the design efficiency, and highlight the liberalization and accuracy characteristics of the modeling process.
