1、济南大学毕业设计摘 要起重机是减轻笨重体力劳动、提高作业效率、实现安全生产的起重运输设备。在国民经济各部门的物质生产流通中，起重机作为关键的工艺设备或重要的辅助设备机械，应用十分广泛。因其与实际生产生活结合比较紧密，是机械、仪表、电气、人机工程等多学科的融合，特别适合作为毕业设计课题，用来检验毕业生的知识结构和强化专业基础。本次设计过程严格按照起重机械的设计规范，讲究设计方法和设计顺序，整合大学期间所学过的相关知识，同时积极学习利用新的知识来解决所面对的问题，极大地的提高了设计效率。本次设计成功地完成了毕业设计任务书上所要求的全部内容，同时，根据实际情况对部分要求做了拓展，比如，在资料收集任务
2、中，参阅量远远超过任务要求；再如，运用三维软件Pro/E模拟整机装配，检验了设计成果的合理性。成果的产生正是一个个过程积累的结果，正是一个得鱼更得渔的过程，经过本次设计，切实提高了设计者分析问题、解决问题的能力，深化了对专业知识的理解。结论，此次设计充分考虑了设备模块化设计的优势，将大车车轮组和小车车轮组定为一个模块，将大车架端梁和小车架端梁定为一个模块，简化了设计过程，节约了设计时间。同时，较为详细地介绍了起重机械设计过程中的常用和通用方法，对类似产品的设计起到了一定的指导作用。关键词：多学科、规范、模拟装配、模块化ABSTRACTCranes are one of hoisting and
