The steel structural standard has the following characteristics: the shape and size of the standard part of the steel structure are fixed. The shape and size of the bolts, nuts, rivets, etc. used in the design are fixed; some steel structural standard parts are fixed in shape but can vary in size. The parameters of some components in the steel structure joint are variable and are determined by the connection information during the steel structure design process. For example, the length of the H-shaped steel in the steel structure is determined by the mating connection relationship and the size interference check in the design process; in the steel structure design, the material list of the standard parts and other characteristics (such as standard parts) need to be generated. Calculation of surface area, weight, etc.). System design and analysis There are many types of design and tooling standard parts commonly used in steel structures, and the shape is complex. Therefore, in the development process, it is not possible to focus on only one type of parts, but should consider most parts characteristics and adopt parametric driving methods. . In addition, in order to improve design efficiency, reduce the repetitive workload of designers, and make full use of previous design results, the system also provides functions such as browsing and retrieving standard parts libraries. The design idea of ​​the system is as follows: analyze and generalize from a large number of specific standard parts, abstract the common shape pattern, as the basic element characteristics of the database, form a parameterized feature database; establish a variety of features in the feature library to form a certain A procedural description of a class of standard parts. This description expresses the configuration information of such parts. This type of information is stored in the node parameterization database; the specific parameters can be used to embody the patterns in the standard parts library, resulting in corresponding Standard part model. For example, the parameters of an H-beam are H, B, tW, tF, r, Length. When a specific parameter value is given, the required standard part model H-beam can be produced; in the specific standard part design, the standard part can be obtained. The standard parts material table, view and construction details are obtained in the database. SolidWorks steel structure standard design system is mainly composed of human-computer interaction interface module, program design module, standard component parameter database and standard component graphics library. The standard part parameter database consists of a basic part parameter database and a node piece database. The standard part graphic library consists of a basic part graphic library and a node piece graphic library. They store the solid modeling and parameterization data of the basic and node parts. The human-computer interaction interface module mainly completes the data transmission, and its function is realized by a dialog box. In the human-computer interaction interface, the user needs to select a node template, parameterized information of the input node, and a file name and path for saving data (parameters and graphics) of the newly generated node. The programming module is mainly composed of a basic component design module and a node component design module, which is the main part of the system. The module retrieves the parameterized data of the standard part in the standard part parameter database and the standard part graphic library according to the parameters input by the user in the human-computer interaction interface module, and performs parameter legality check, and then performs parameterized standard part design. Generate standard parts of the required specifications, and finally use SolidWorks' own functions to generate three views and bills of materials for the corresponding standard parts. Steel structure standard parts design system features, friendly interface. The SolidWorks-based steel structural standard design system is a secondary development in the SolidWorks environment. It makes full use of the excellent interface of SolidWorks and is very convenient to use. The user can arbitrarily create, modify, and delete standard parts during the standard part design process. When the user inputs the characteristic parameters of the standard three-dimensional standard parts, the first work of the system is to analyze the rationality of the parameters for the user. If an illegal input is encountered, the system will give the user corresponding prompts and suggestions.
