【摘要】：门式起重机被广泛应用于国民经济建设的各个领域,产品已经形成多个系列,随着经济建设的发展,用户对其设计要求越来越高。因此起重运输机械的设计方法需要不断地更新和完善,使其更注重经济性、科学性、可靠性和安全性。在传统的起重机设计过程中,涉及到的参数众多,计算公式繁琐,人工计算效率低、设计过程不直观、设计过程中的错误也不容易发现,设计中往往需要多次反复修改、重复性工作多,很显然这样的设计方法已不能适应现代起重运输机械发展的需要。同时,对功能相似或结构相近的同系列产品(包括一些标准件)在该系列已有产品设计的的基础上进行系列化相似性设计也能大大提高产品设计的效率,因此,新的设计方法的应用迫在眉睫。随着计算机技术的发展,各类设计软件的不断涌现和升级,为起重机设计水平的提高提供了软件支持。参数化设计技术的发展也为提高起重机设计效率提供了理论和技术支持。利用计算机强大的运算功能,结合各种设计手段和先进的设计理念进行设计是起重运输机械设计的发展趋势。 为此,本文以MDG40门式起重机为例,对主梁结构进行参数化设计的研究。本文设计的L型电动单梁门式起重机主梁结构参数化设计系统是在研究门式起重机结构特点、设计流程、设计方法的基础上,以Visual Basic6.0为开发平台,运用有限元分析软件ANSYS进行参数化建模和优化分析,以Access为后台数据库,利用Visual Basic6.0语言对SolidWorks提供的API函数进行二次开发而形成的一个系统。该系统结合设计工程师的设计经验以及门式起重机的设计理论,充分考虑企业的实际需求,采用面向对象的系统设计方法以及模块化的系统划分方法。 本文首先研究了系统开发的几个关键技术,建立了常用零部件模型库、工程图库和数据库。并重点开发了L型电动单梁门式起重机主梁结构参数化设计系统。 本课题开发的门式起重机主梁结构参数化系统,界面友好,设计直观,模型自动生成,能迅速发现干涉等装配问题,图纸可自动更新,减轻了设计工作量。不仅可以提高设计效率和设计质量,而且也符合了现代设计发展的要求。本课题研究旨在为门式起重机的研发提供一种先进、可靠、快速的设计系统。
[Abstract]:Gantry cranes are widely used in various fields of national economic construction, and many series of products have been formed. With the development of economic construction, the design requirements of gantry cranes are becoming more and more high. Therefore, the design method of hoisting and transportation machinery needs to be updated and perfected constantly to make it pay more attention to economy, science, reliability and safety. In the traditional crane design process, there are many parameters involved, the calculation formula is cumbersome, the manual calculation efficiency is low, the design process is not intuitive, and the mistakes in the design process are not easy to find. It is obvious that this design method can not meet the needs of the development of modern hoisting and transportation machinery. At the same time, the serial similarity design of the same series of products (including some standard parts) with similar function or structure can greatly improve the efficiency of product design based on the existing product design of the series. The application of new design method is urgent. With the development of computer technology, various kinds of design software are emerging and upgraded, which provides software support for the improvement of crane design level. The development of parameterized design technology also provides theoretical and technical support for improving the efficiency of crane design. The development trend of crane transportation machinery design is to utilize the powerful computing function of computer, combine all kinds of design means and advanced design idea. Therefore, this paper takes the MDG40 gantry crane as an example to study the parameterized design of the main girder structure. The parameter design system of L-type electric single-beam gantry crane is developed on the basis of studying the structural characteristics, design flow and design method of gantry crane, and taking Visual Basic6.0 as the development platform. A system is formed by using the finite element analysis software ANSYS for parametric modeling and optimization analysis, taking Access as the background database and using Visual Basic6.0 language to develop the API function provided by SolidWorks. Based on the design experience of design engineers and the design theory of gantry cranes, the system fully considers the actual needs of enterprises, and adopts object-oriented system design method and modular system partition method. In this paper, several key technologies of the system development are studied, and the common parts model database, engineering drawing database and database are established. The parameter design system of L-type single-beam crane is developed. The structure parameterized system of gantry crane developed in this paper has friendly interface, visual design, automatic generation of model, quick discovery of interference and other assembly problems, automatic updating of drawings and reduction of design workload. It can not only improve design efficiency and design quality, but also meet the requirements of modern design development. The purpose of this research is to provide an advanced, reliable and fast design system for gantry crane.
