Classification of structural standard parts The purpose of classification is to support fast and efficient retrieval, shorten the search time, facilitate the use of duplicates, and systematically manage parts <2>. Based on the above design ideas, we start from the functional properties and structural properties of steel structural standard parts, and divide all standard parts of steel structure into two categories: basic standard parts and node standard parts. The basic standard parts represent the basic parts commonly used in steel structures. They all have fixed models and are only specific in size in practical applications. The node standard represents the relative position and connection between the node parts.
The specific classification of standard parts by this standard design system is described. Standard Parts Classification System Implementation The main purpose of the feature-based parametric steel structure standard part retrieval system is to improve design efficiency, reduce the repetitive workload of designers, and make full use of the results of previous designs. The system starts from the parameterization of the characteristics of steel structural standard parts, takes the requirements of the designers as the starting point, fully summarizes the previous design results, and achieves the purpose of the parts retrieval system. The system has the functions used by the general parts retrieval system, such as adding, deleting, modifying, and retrieving.
Key Technology for Realizing Steel Structure Standard Parts Retrieval System Object-Oriented Method The object-oriented method is a cognitive method that provides a generalized to a special deductive means, and also provides a generalized to generalized form of induction. The object-oriented method describes the real system in a way that is more in line with people's cognitive habits. The problem space and the solution space have a more direct mapping relationship <3>. The basic principle of object-oriented technology is to realize the natural segmentation of the problem solving domain, establish the solution model according to the usual way of thinking, and design the program <4> to solve the problem as directly and naturally as possible.
Parametric technology has been widely used in CAD systems. Database Access ODBC is an integral part of the database in Microsoft's Open Services Architecture, WOSA, which establishes a set of specifications and provides a set of standard APIs for database access. These APIs use SQL to perform most of their tasks.
Conclusion Steel structure standard parts retrieval system is an important part of steel structure design and detail design software. The system uses an interactive search interface to quickly and efficiently utilize previous design results. The standard parts of steel structure have too many standard parts of steel structure due to too many joint forms, too complicated, and the production design habits of various manufacturers and design institutes. In the system design process, the designer fully considers this point and makes the system have good scalability.
As a common transmission force device, the stainless steel chain reduces friction through the "chain" design of the hyperbolic arc, and is used in places where the power is relatively large and the running speed is relatively slow, which has obvious advantages over belt transmission, such as Tanks, pneumatic compressors, etc., but the transmission speed can not be too fast, because the flexibility of the chain is not as good as the belt transmission.
