A Design Method for Motor Vehicle Drive Axle

Abstract

The invention belongs to the technical field of mechanical designs and relates to a motor vehicle drive axle design method. The motor vehicle drive axle design method includes performing attribute matching comparison on instance features and design requirements according to user's design parameters, calculating similarities of all instances, extracting the instances with the maximum similarities as base models of variant designs, and modifying the instances with the maximum similarities, wherein amended solutions are used as new instances which are to be stored in an instance base. The motor vehicle drive axle design method is reliable in design principle, advanced in design thinking, high in design accuracy, short in time, environmental friendly, and capable of saving man-human resources, and effectively improving design efficiency and design qualities.

Description

Technical field: [0001] The invention belongs to the technical field of mechanical design, and relates to a design method of a drive axle of a motor vehicle. With the help of an intelligent design platform of a drive axle, a case-by-case reasoning method in knowledge engineering is used to design components and realize the automatic design of a drive axle of a motor vehicle. Background technique: [0002] Case-based reasoning (case-based reasoning, CBR) technology originated in the 1970s. It is a similar or analogous reasoning method, which generates new products through direct reference to similar examples of successful design and necessary modifications. With the development of computer and artificial intelligence technology, the reuse of design knowledge and design experience has promoted the development of case-based reasoning, an artificial intelligence technology, in the field of product design. At present, the application of CBR in the field of mechanical products mai...

Problems solved by technology

The existing intelligent design platform for motor vehicle drive axles generally includes a parametric modeling module, a finite element analysis module and a dynamic analysis module. Through the VB.NET programming language, Pro / E three-dimensional modeling software, ANSYS finite element analysis software and ADAMS The dynamic analysis software is integrated to realize the data transfer and exchange among various modules, and the database management system manages a large amount of data in the platform. The designer inputs the required parameters through the system interface, and the platform realizes the parameters of drive axle components. Then drive the 3D modeling software to generate a new model, then automatically perform parametric finite element analysis on the parts that need finite element and dynamic analysis, and modify the design plan according to the analysis results; but the existing design method The process is complicated, the design cycle is long, the design accuracy is low, and the design automation performance is not high, which has the disadvantage of wasting man-machine resources to a certain extent.
