[Abstract]:The design results of vertical gearbox above 5000kW require high reliability, and the whole process needs to be calculated and checked repeatedly to meet the design requirements. In addition, the engineering drawing of the gearbox has a large amount of work. When the design parameters are changed, the workload of the modification of the gearbox is very large, which makes the design process of the gearbox complex and cumbersome. The enterprise is eager to develop a gearbox rapid design system to realize the semi-automatic process of gearbox design from scheme design to structural design in order to reduce the working pressure of designers and improve the design efficiency and product quality of the gearbox. According to the requirements of the enterprise, this paper designs and develops the gearbox rapid design system, solves the problem that the gearbox design is difficult, the drawing workload is large, realizes the gearbox fast design. The main work of this paper is as follows: in view of the complexity and particularity of the structure and function of nuclear power gearbox, the axiomatic design method is introduced into the scheme design process, and the application of axiomatic design method in the gearbox scheme design is studied. The non-coupling decomposition of the scheme design is realized to ensure the rationality of the gearbox design. In order to realize the parameterized design of the series gearbox, based on the basic idea of modular design, the methods and processes of module partition, module query and module integration are studied respectively, which provides the basis for the parametric design of the gearbox. In this paper, the changing process of structure driving graph and dimension driving graph in parametric design is studied. The method of establishing structure constraint relation and dimension constraint tree is proposed, and the driving model is established to realize the parameterized driving process of the graph. Based on the above research methods and techniques, the system structure, function setting and work flow of the gearbox rapid design system are designed, and the gearbox rapid design system is developed. The system can realize the process of gearbox scheme design from basic design parameters to semi-automatic design, and automatically generate more than 100 engineering drawings of vertical gearbox above 5000kW according to the design result of the scheme. The parameterized and rapid design of gearbox is realized better.
