Аннотация:The article describes the development of the software system for selecting the main modes of the diffusion welding technological process, with the implementation of the antifriction coatings based on fluoroplastics. The description of the algorithms for determining the main technological regimes from the entered necessary values of the tensile strength and wear rate, working conditions, operating temperature range, and the required composition of the material is given. The choice of the main parameters values of the technological process is made according to the maximum value of the tensile strength and the calculated value of the wear rate. According to the developed algorithm, the current values of the main parameters of the technological process are calculated. In case of insufficient strength of the joint or exceeding the value of the wear rate, the technological parameters are adjusted within the established limits or the coating material is replaced. For the decision support system in the design of technological processes, information bases were developed on the existing modes of polymeric materials diffusion welding to substrates of various types, and a database of tribotechnical information. The information database is implemented in a three-purpose software shell: 1) for entering and searching information in the database by fields, 2) for the work of an expert technologist, for linking information fields on topics, technologies, materials, 3) for work in the information mode, and in the mode of issuing an information array for process control. The constructed models and databases made it possible to create an algorithm for automating the diffusion welding process with the definition of the main modes. An algorithm for automating the selection of the diffusion welding main modes has also been developed. For the implementation of the “query generation” unit of the enlarged search algorithm, a production model of knowledge representation was used. As a result of the algorithm, an array of information is transmitted to the following modules of the algorithm. Databases were filled and logical connections of knowledge representation were established.
