1、 机车车体论文：基于 UG 的机车车体模块化设计研究【中文摘要】铁路作为我国重要的基础设施、国民经济的大动脉以及大众化的交通工具,对经济社会的发展有着巨大的推动作用。铁路运输的发展,对机车功率及速度需求变化幅度增大,同时要求交货时间短,而且一个批次订货数量不大,有时甚至不超过 10 台。另外,随着新技术的开发与应用,机车升级换代的周期多小于一般 35 年的机车寿命。这样,原有的机车设计制造技术已不能满足与适应迅速变化的市场需求。为此论文研究机车车体先进设计技术,采用基于系统工程思想的模块化设计,通过标准的结构模块与功能模块的组合,以先进的计算机辅助技术为依托,解决了通用与定制要求之间的矛盾,提
2、高了设计制造的效率和质量。论文首先通过对车体各部分主要结构特征的分析,利用模块划分原理对车体结构进行了模块划分,确定机车车体的主参数和各个模块的结构参数,同时分析建立参数之间的关联关系,包括形状关联和尺寸关联。其次研究了基于 UG 的模块化设计实现流程。一方面,基于 UG 软件技术UG WAVE 技术和部件间表达式建模技术实现了模块化建模,并建立工程图快速生成系统。另一方面,研究基于 UG 二次开发的机车车体模块化设计关键技术,以UG/Open 作为开发工具创建车体模块化设计系统的菜单资源文件和用户界面资源文件。最后在 Windows XP 操作系统下,以 VC+6.0 为开发平台,编写机车车
3、体模块化设计系统的主控程序,并以 Access 为后台数据库,建立了机车车体模块化设计实验系统。该系统入机界面良好,操作方便,能有效提高机车车体的设计效率,有一定的实用价值。【英文摘要】Railway is an important infrastructure.

4、 a variety of requirements for locomotives concerning aspects like power and speed, and other requirements also include delivering on scheduled. Even under such circumstances, the locomotive order is still small, and some are ordered no more than ten. Besides, a locomotive can serve more than 35year
5、 in its lifetime, but as new-technology has been developed and applied on new locomotives, the upgrading cycle for a new-locomotive is less than that, therefore, the old manufacture techniques can no longer adequately handle and meet the swiftly-changed market requirements.So, the advanced design te
