Intelligent Design Technology And Application Of Shaft System Components

Shaft components are widely used and play a very important role in mechanical products and their performance has a direct impact on the efficiency of the machinery.The shaft design process contains a large amount of design information,of which nongeometric information accounts for the majority of the overall shaft design knowledge,such as product materials,design rules,diagram formulas,strength requirements design etc.Therefore,the integration of the design knowledge of the shaft system components with the model and the knowledge-driven design becomes an important means to improve the speed of the development of the shaft system components.In response to the current problems of low intelligence in the design of shaft system components and low integration of design knowledge and feature models,a design knowledge process driven intelligent design method is proposed,with the following main research tasks.First of all,the analysis of knowledge-driven intelligent design principle,its core is the knowledge-driven process customization system to customize product knowledge,using the system of various functions of the visual frame to express product knowledge,at the same time combined with the design process judgment,cycle,nested structure form reasonable organization flow frame running sequence and hierarchical structure.Secondly,the knowledge of design principles and strength checking of axis components is analyzed and sorted,and the general process of axis component design knowledge and the nesting sub-process of main components are constructed.Then,the skeleton model of the product is established in combination with the correlation design technology,and the secondary development technology is used to build the features,and the skeleton model and feature template are linked with the customized visual flow frame of the system to form a design knowledge process integrating parameter calculation and feature modeling.Finally,the design and construction process of axle components in the secondary reducer is analyzed.Based on the input of known relevant engineering parameters,the system calculates a set of parameters that meet the design requirements.Through the knowledge-driven process to customize the system drive skeleton,call the feature template and write the design parameters,the instance model of axle parts is obtained,and the intelligent design process of axle parts driven by the knowledge process is realized.The practical results show that the knowledge-driven intelligent design approach can be effectively applied to engineering practice,improving product design efficiency and shortening product design time through the reuse of design calculation knowledge and user feature knowledge.
