【摘要】：5000kW以上立式齒輪箱的設計結果要求較高的可靠性，整個過程需要反復計算和校核才能滿足設計要求。此外，齒輪箱工程圖的繪制工作量較大，當設計參數(shù)改動時，圖紙的修改工作量很大，使得齒輪箱的設計過程變得復雜而繁瑣。企業(yè)迫切希望開發(fā)一套齒輪箱快速設計系統(tǒng)，實現(xiàn)齒輪箱從方案設計到結構設計的半自動化過程，以便減輕設計人員的工作壓力，提高齒輪箱的設計效率和產(chǎn)品質(zhì)量。本文根據(jù)企業(yè)要求，設計開發(fā)齒輪箱快速設計系統(tǒng)，解決齒輪箱設計難、繪圖工作量大的問題，實現(xiàn)齒輪箱的快速設計。本文的主要工作如下： 鑒于核電齒輪箱結構及功能的復雜性和特殊性，其方案設計過程中引入公理化設計方法，研究公理化設計方法在齒輪箱方案設計中的應用，實現(xiàn)方案設計的非耦合分解，保證齒輪箱設計的合理性。 為實現(xiàn)系列化齒輪箱的參數(shù)化設計，基于模塊化設計的基本思想，分別研究齒輪箱模塊劃分、模塊查詢和模塊集成的方法與過程，為齒輪箱的參數(shù)化設計提供基礎。 研究參數(shù)化設計過程中結構驅(qū)動圖形和尺寸驅(qū)動圖形的變化過程，提出了建立結構約束關聯(lián)關系和尺寸約束樹的方法，建立了驅(qū)動模型用以實現(xiàn)圖形的參數(shù)化驅(qū)動過程。 基于上述研究方法和技術，對齒輪箱快速設計系統(tǒng)的體系結構、功能設置及工作流程進行設計，開發(fā)了齒輪箱快速設計系統(tǒng)。系統(tǒng)可實現(xiàn)從基本設計參數(shù)到半自動完成齒輪箱方案設計的過程，并根據(jù)方案設計結果自動生成5000kW以上立式齒輪箱100余張工程圖，較好的實現(xiàn)了齒輪箱的參數(shù)化快速設計。
[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.
