摘 要
长期以来，甲板起重机的设计主要依靠经验判断，此方法不仅被动地设计而且在设计过程中浪费大量资源。本课题针对镇江金舟船舶设备有限公司设计的10t 10m甲板起重机吊臂的结构特点，利用系列化理论得到扩展吊臂，分别运用参数化方法及程序语言设计吊臂并对其进行系统开发，对提高设计效率与增强管理能力有很大的帮助。
本论文的主要研究内容及创新工作包括：
1. 以上述甲板起重机吊臂为研究对象，分析其结构与受力情况并计算吊臂在最不利工况下的受力。运用ANSYS的二次开发工具APDL，将吊臂的建模、计算分析、结果查询等不同功能的操作命令封装至各个宏，实现吊臂设计专用系统的开发。在此基础上，研究系列化设计方法并以此指导吊臂的系列化设计。
2. 运用系列化设计理论——相似原理，结合吊臂受力分析，提出了一种吊臂系列化设计方法，并在原吊臂的基础上设计出变型吊臂。通过原有的宏文件，分别计算吊臂系列的结构强度，分析结果符合理论计算，验证了该系列化设计方法的正确性。
3. 以生成的分析文件为基础优化吊臂系列，得到吊臂系列改进设计。利用已有宏文件分析改进吊臂，数据显示改进后的吊臂强度和刚度提高，体积减少，与系列化设计结果吻合，再次验证了本课题中系列化设计方法的可行性。
4. 基于吊臂系列优化前后的尺寸参数与静力学结构分析结果，利用C#语言和SQL Server 2000数据库技术和Pro/E软件，开发吊臂系列化设计系统。实现了将吊臂系列的概念设计、分析与优化、数据管理以及结构设计结合，完成了CAE/CAD/PDM系统的集成，完善本课题对吊臂的系列化设计。

Abstract
For a long time, traditional design of deck crane is based on experience, which not only designs passively but also wastes a lot of manpower and resources in the design process. By studying the structural characteristic of 10t 10m deck crane boom of a Tianjing company, a series of crane booms were designed by using the theory of serialization design. Crane booms were designed by using parametric design method. Crane boom system was developed through utilizing programming language, which hleps to improve the design efficiency and enhance the management capacity.
The main contents of this paper include:
1. After analyzing the structure and the force of deck crane boom studied in this paper, each force in the most adverse working condition was calculated by utilizing ANSYS Parametric Design Language (APDL), different functions of modeling, calculating, analyzing and checking results were set into different micro files, which helps to achieve the appropriate system of crane boom parametric design. Based on these, a serialization design method was studied to guide the serialization design of crane boom in this paper.
2. By using serialization design theory, similarity principles, and combining with the force analysis of crane boom, a serialization design method for crane boom in this thesis was advanced and a series of crane booms were designed based on the original boom. The structural strength of the extended booms were calculated and analyzed by using the existent micro files, respectively. The results showed that, analyzing results are close to those are calculated according to this design method, which proved the correctness of this serialization design method proposed in this paper.
3. Based on the generated analysis file, the series of crane booms were optimized. Improved crane booms were obtained and analyzed by using the same micro files. The analyzing results revealed the structure strength of improved crane booms still satisfied the requirements of design and their volumes were less than they were used to be, which verified the feasibility of the serialization design method again.
4. According to the size parameters and structural analysis results of crane booms before and after optimization, program language C#， SQL Server 2000 database technology and software Pro/E were applied to implode the serialization design system of crane booms. The system realizes the collection of conceptual design, analysis and optimization, data management and structural design of crane booms, and achieves the integration of CAE/CAD/PDM systems, which consummates the serialization design of crane booms in this thesis.
