Slewing CAD research and development

In the design of slewing expert system technology, finite element analysis and parametric drawing technology to construct a set of design, structural analysis, and automatic drawing in one of the rotary Bearing test machine CAD systems, introduced the system's structure and main modules set rotation supporting widely used in automobile cranes, excavators and other construction machinery and mining machinery radar, automatic tracking artillery and other military products. Slewing ring design theory of research carried out less, essentially using traditional design methods, design standards and bench are behind Germany, Japan and other developed countries.
There are many types of slewing ring, it is designed both types of options, there are forces and structure size calculations, set the value of the non-expert planning, and numerical reasoning process of scientific computing in one. Therefore, in the design of slewing expert system technology, with major engineering application value. Survey showed that in the low-speed heavy slewing generally work under conditions, resulting in the failure of the cause is due to structural weak part of insufficient strength. Therefore, slewing static finite element structural analysis, which can effectively predict slewing bearing capacity and weak links, and process re-engineering measures for the adoption direction. Parametric drawing technology in the CAD system design and development in an increasingly wide range of applications, its advantages in systematic product engineering drawing is particularly prominent. In this paper, the full collection and analysis of slewing ring design data and design experience, based on the research and development of design, structural analysis and automatic drawing in one of the rotary bearing CAD system.
Slewing system architecture and design CAD ​​system brings together the database technology, knowledge base technology, computing and reasoning techniques, finite element analysis techniques and parametric drawing technology. The system consists of expert system design, finite element analysis and parametric drawing three parts. Both between the various parts combination, collaboration, and functional independence, each module can be used alone as a subsystem through the system function of each module framework will combine to satisfy the needs of users
