摘要
随着现代化工业的飞速发展、生产规模的不断扩大，市场对起重运输机械的要求也越来越高，这就对起重机的设计提出了更高的要求。门座式起重机作为起重机的一个工种，具有工作性能良好、通用性较强、作业高速灵活、自身性能安全可靠等优点，是当前时期国内一些主要港口中，数量最多、使用频率最高的电动装卸机械设备[3]。对于起重机而言，现有的传统的设计方法不论是在设计水平还是设计效率等方面，都难以满足高速发展的现代化工业的生产需求[1]。起重机设计需要采用更加先进快速的设计方法和手段，以便达到最大程度的缩短设计周期、简化设计过程并使其变化更加灵活、提高整机的性能，从而推动这个起重机设计行业和现代化工业的发展。
因此，本课题“42t-33m门座式起重机整体与象鼻梁结构参数化设计”，以门座起重机作为研究对象，重点在于门座起重机象鼻梁结构的设计。以三维设计软件Solidworks为建模工具建立三维模型，以Visual Basic 6.0 作为开发语言，通过相关接口程序和编程语句实现对所建模型的参数化控制，从而达到快速设计、缩短设计周期、优化起重机结构的目的。具体内容如下：

    阐述国内外门座起重机的发展现状以及参数化设计技术在起重机上的运用状况，并且说明该课题的研究意义；
    以42t-33m门座起重机金属结构作为研究对象（本人主要负责象鼻梁部分），基于三维建模软件Solidworks，设计、简化并构建象鼻梁的三维模型。
    基于Visual Basic 6.0，通过编程语句实现VB与Solidworks的连接，实现用程序控制象鼻梁相关尺寸的改变，达到参数化的目的。从而实现了门座起重机整机金属结构尺寸的参数化，力求避免繁琐重复的设计与计算，缩短设计周期。
    从同组组员处，通过变尺寸的方法获得能与自己所建机构进行装配的其他工作结构的三维模型，通过施加相关配合，完成整机装配。再用ANSYS的workbench协同仿真环境对所装配的整机三维模型进行有限元分析，判断整机结构是否合理

Abstraction
With the rapid development of modern industry and the continuous expansion of production scale, the market demand for lifting and transporting machinery is getting higher and higher, which puts higher requirements on the design of cranes. As a kind of crane, the portal crane has the advantages of good working performance, strong versatility, high speed and flexible operation, and safe and reliable performance. It is the electric handling equipment with the largest number and the highest frequency of use among some major ports in China. For cranes, the existing traditional design methods are difficult to meet the production needs of high-speed modern industrial development, both in terms of design level and design efficiency.The crane design needs to adopt more advanced and rapid design methods and means, which has promoted the development of the crane design industry and the modern industry by minimizing the design cycle, simplifying the design process and making the changes more flexible and improving the performance of the whole machine.

Therefore, the subject "parametric design of 42t-33m portal crane and elephant trunk bridge structure", with the portal crane as the research object, the focus is on the design of the portal crane nose bridge structure. The 3D design software Solidworks is used as the modeling tool to build the 3D model. With Visual Basic 6.0 as the development language, the parameterized control of the built model is realized through relevant interfaces and programmatic statements, which has achieved rapid design, shortened design cycle and optimized crane structure. the goal of. The details are as follows:
(1) Explain the development status of the domestic and foreign gantry cranes and the application status of the parametric design technology on the crane, and explain the research significance of the subject;
(2) Taking the metal structure of 42t-33m portal crane as the research object (I am mainly responsible for the trunk and nose beam part), based on the 3D modeling software Solidworks, design and construct the 3D model of the trunk bridge. [来源：http://www.doc163.com]
(3) Based on Visual Basic 6.0, realize the connection between VB and Solidworks through programming statements, realize the variable size of the trunk and nose, and achieve the purpose of parameterization. Thereby, the parameterization of the metal structure design of the portal crane is realized, the complicated design and calculation are avoided, and the design cycle is shortened.
(4) The finite element analysis of the established three-dimensional model of the trunk bridge by the simulation of Solidworks's own module makes the model structure meet the requirements reasonably and completes the assembly of the portal crane.
